A winch is a unit that is used to move or vertically lift heavy structures using a flexible cable, rope or chain. The latter are connected to a drum, which can have several drive options.
The simplest of them is manual: it is more durable than the others, but it is not suitable for daily use and heavy loads: the operator will quickly get tired. Electric winches are reliable, structurally perfect and solve a much wider range of problems than manual ones. The only negative is the dependence on power supply, which is not always available in the field or on rough terrain. The most practical and trouble-free unit is a winch based on an internal combustion engine: it creates high power and works in any conditions, even in places where no one has gone before.
Unfortunately, production models of such equipment cost a lot, and not everyone can afford them. In this case, homemade products come to the rescue - homemade winches driven by a chainsaw or special ready-made adapters that will turn an ordinary household chainsaw into a miniature analogue of a crane - a motorized winch. Let's take a closer look at how you can do this at home.
Winch attachment for a chainsaw - advantages and functions
Making your own towing mechanism from a chainsaw requires the use of certain tools.
However, not everyone has the necessary dexterity when working with a drill and welding machine. In this case, you can buy an attachment that is equipped with a household chainsaw. The winch attachment for a chainsaw is small in size and simple in design. It is easy to install by connecting the elements necessary to transmit torque to the engine. If necessary, the product can be removed. On average, this takes no more than 5 minutes.
Today, towing attachments are produced by many well-known manufacturers. These structures can be used for towing cars weighing up to 2.5 tons, as well as for clearing the local area and roadway from fallen trees or concrete damage.
The “Winch” attachment for a chainsaw is a simplified way to make a traction structure out of a chainsaw
Designing and assembling a winch from a chainsaw with your own hands, although it does not require global technical knowledge, does require a certain skill, which not everyone has. For most, an easier way is to purchase a ready-made set - a “Winch” attachment.
Additional devices - “Winch” attachments for chainsaws are produced for most modern chainsaws and differ in traction force, cable length and dimensions. With their help, you can easily move a fallen tree from the roadway, pull a car out of a ditch, moor it to the shore, or clear debris in case of an emergency.
Types of homemade winches
Any drawing will tell you how to assemble a useful device. A car winch remains a necessity, so don't give it up. First, you should get acquainted with the available options that guarantee ease of assembly. There are the following types of these devices:
Homemade winch - a simple device
In accordance with the schemes used, it will be possible to select the optimal winch. If desired, a person will independently make a suitable model that will meet his needs. This is why it is worth considering each type in detail, giving it a general description.
Manual
A homemade hand winch is an excellent choice that guarantees ease of operation. This is its main advantage, allowing you to freely use the device without facing the problem of a low battery. The only problem is that it requires a lot of effort.
The design of such an accessory becomes complex. Calculations must be made to obtain sufficient power. Otherwise, it will correspond only to the physical strength of a person. He will not be able to pull the SUV out of the ditch, so the installation will not give successful results.
A manual winch from the starter is the most affordable option that you can choose for your own car.
By using it, you will be able to quickly assemble a reliable structure that can cope with the task in any weather.
How to extend the life of a homemade mechanism?
The reliability of a homemade winch directly depends on the quality of its assembly. In addition, there are a number of other factors that affect the duration of the application of the mechanism.
These include:
- well-coordinated clutch operation. To do this, the owner of a chainsaw winch must constantly monitor the condition of the main parts of the unit. If necessary, any worn part must be replaced;
- ideal engine condition - operation of the mechanism is not allowed if the engine is not running well. This will not only lead to increased wear on the internal combustion engine, but will also increase the risk of damage to the object that needs to be pulled out. The engine must operate equally stably, both at idle and at high speeds;
- reliability of fastening of safety elements. During intensive use of a homemade winch, you need to regularly check the condition of the anchor hooks, belts and other parts. If at least one of the spare parts is faulty, this will increase the risk of injury to the operator and loss of the towed object;
- correct operation of the starter. If the trigger mechanism works intermittently, then this will turn the use of the winch into a real test for its owner;
- reliability of the tow rope. Safety when working with the mechanism depends on its serviceability. If one of the cable strands breaks, it will need to be completely replaced;
- proper quality of fuel and oil. In order for the engine to last for a long time, you need to use only high-quality branded oils and gasoline with an octane number not lower than that specified in the instructions to refuel it.
A winch driven by a chainsaw can last much longer than its full-fledged branded counterparts. However, to do this, you need to regularly check it and replace faulty parts immediately after detecting a breakdown.
Helicopter
This type of homemade product is considered complex and therefore has not been implemented to date. She is in the dreams of enthusiasts, in invented stories. One of them claims that back in the USSR, a prisoner who understood mechanics made a helicopter with a chainsaw engine and was able to escape from the colony.
Making a homemade helicopter requires, unlike a snowmobile, outboard motor, bicycle, grinder and even a snow blower, more complex engineering calculations. They also show that one, even powerful, engine is not capable of lifting such an aircraft into the air. At least 4 motors are required, moreover, forced and working in concert at the highest possible speed. But it is difficult to implement this with chainsaw engines in practice.

Chainsaw winch - design, features, attachment
A winch is a stationary or portable equipment whose main function is to pull or tow large objects.
This device can be made from available materials, for example, from an old chainsaw.
In the future, the finished winch can be installed on a car or tractor in order, if necessary, to remove a stuck vehicle or tow another agricultural implement to the nearest workshop.
What are the advantages of homemade winch assembly?
A homemade chainsaw winch allows the manufacturer to save a significant amount of money.
In addition, assembling the necessary device with your own hands gives the designer several other advantages:
- the ability to manufacture a winch with the dimensions needed for further unhindered installation and operation;
- the ability to use during manufacturing those components that are at hand;
- ease of regular maintenance;
- ease of self-repair.
In addition, a winch driven by a chainsaw does not need to be constantly connected to an electrical power source. It does not need to be connected to a battery, which saves battery life. It is enough to fill the device with a small amount of fuel mixture prepared from high-quality gasoline and branded semi-synthetic motor oil.
DIY chainsaw winch
Having collected everything necessary for work, the manufacturer can begin directly assembling the winch.
To do this you will need:
- Weld a strong frame that is highly resistant to vibration and shock. The base of the frame is a thick steel plate, to the back of which the internal combustion engine from the chainsaw will be attached, and to the middle - a drum with a cable wound around it. The gearbox, control mechanism and other auxiliary elements must be attached to the plate using bolted connections and ties;
- Attach the motor and drum. If there is another chainsaw on the farm, then the power unit from the gas-powered tool used can be welded with a thick continuous seam. This will give the overall structure stability and increased endurance. It is also best to secure the drum by welding;
- Connect the gearbox used to the motor. Mechanisms must be secured using clamps. The connection of the element itself must be done using a shaft - it will play the role of a link connecting the motor and the moving drum with the cable;
- To be able to automatically start the drum, you need to connect the winch control lever to it. The lever must be connected to the shaft using cam clamps. Thus, when moving the lever to one side, the drum will begin to rotate, and when changing the position of the lever, it will stop and lock in the position required for towing;
- To assemble the anchor, you can use pointed corners. With its edges, the element must firmly and motionlessly stick into a stationary object;
- The anchor must be attached to the frame using hinges. A steel holder will be responsible for lifting the element in the winch device.
After assembling the device, it must be tested. The operator should first test the equipment with light weights. If, while dragging, the chainsaw winch does not make any extraneous sounds and confidently copes with the load, then you can proceed to checking the homemade product with a larger load.
Winch attachment for a chainsaw - installation and operation features
Some well-known brands produce ready-made accessories for their chainsaws, technologically manufactured in the form of small portable attachments. These manufacturers include Stihl, Husqvarna, Patriot, Champion and AL-KO.
The winch attachment for a chainsaw is easy to install and remove. To install the equipment, you will need to first dismantle the cutting parts of the chainsaw. In this case, the clutch elements of the tool must remain in place. Next, you need to install the winch on the shaft, first putting the standard gearbox on it, and then all the other elements of the attachment.
Despite its relatively small size, the branded winch for a chainsaw stands out for its fairly high traction characteristics. It is capable of short-term towing of vehicles weighing up to 1 ton, as well as gradual removal of a stuck object weighing 1.2–1.5 tons.
Ready-made attachments in the form of winches do not require regular maintenance or frequent repairs. All the operator needs is to monitor the condition and winding of the tow rope, and also check the level of fixation of the standard bolted connections of the equipment.
Starting motor transmission gearbox
The function of the mechanism is to switch on the rotation transmission to the diesel flywheel, as well as automatically turn it off after starting the tractor engine. The starter transmission housing is attached to the rear wall of the diesel engine and is connected to the lower plate of the distributor gearbox, receiving rotation from the intermediate gear. The mechanism is lubricated with diesel oil, filled to the level of the control hole in the gearbox housing. The level is monitored every 240 hours of operation. The oil is changed at intervals of 960 hours of tractor operation.
Starter clutch reducer assembly
The device includes the following mechanisms:
- friction clutch gear
- roller overrunning clutch automatic release
- Bendix is a mechanism that controls a gear that meshes with a diesel flywheel.
- levers and clutch engagement drive,
PD-10 starting motor transmission device
With the help of a driver, a gear sliding along the splines of the shaft engages with the rim of the engine flywheel. The on position is held by latching weights, which are fixed by spring force. When the starting engine is running, the clutch gear does not transmit rotation to the shaft as the driving clutch discs are not connected to the driven ones.
The clutch drive drum is riveted to the gear and rotates together with the drive disks, since the drum leads fit into the grooves of the disks. The driven ones are connected by their protrusions to the overrunning clutch bushing and rotate with it.
The overrunning clutch interacts directly with the shaft and is housed in a separate bushing. The bushing itself is both the driven part of the clutch assembly and the driving race of the overrunning clutch. The operating principle consists of jamming four symmetrically located rollers spring-loaded through pushers into the wedge-shaped recesses of the bushing.
Engaging the starting motor clutch
By smoothly moving the control lever to position II, the movable stop 26, interacting with the engagement drive through the ring gear, rotates and runs into the protrusion of the fixed stop 27. In this case, the pressure plane of the stop shifts along the axis to the right, connecting the clutch disks. The rollers 25 of the overrunning clutch jam, and shaft 24 begins to rotate, moving it onto the Bendix gear in engagement with the diesel flywheel 23.
Control PD 10 tractor MTZ 80
Automatic overrunning clutch disengagement
Having started the diesel engine, with an increase in rotation speed, torque begins to be transmitted from the flywheel, trying to drive the crankshaft of the starter through the transmission shaft with the power of the running diesel engine. In this case, the clutch rollers, due to the higher shaft speed obtained from the diesel engine in relation to the overrunning clutch bushing, compress the springs and exit into the wide part of the grooves. As a result, the coupling sleeve is automatically disconnected from the shaft, and the reverse transmission of rotation to the starting motor stops.
Automatic bendix release
At the same time, the increased centrifugal force spreads the Bendix latch weights, freeing the bushing protrusions from the hooks. The sliding gear disengages from the flywheel under the action of a spring and a pusher. Thus, the automatic disconnection of the starter transmission gear engagement from the tractor engine flywheel ring is triggered.

Light weight and solid power combined with compact dimensions allow this “lumberjack’s dream” to be combined with an ice auger and a bicycle, a sawmill and a winch.
Anyone who can confidently work with a welding machine, an angle grinder, and, if necessary, can even use a lathe, can make interesting homemade products from a chainsaw with their own hands.
In this case, knowledge of the basics of design and drawing will be very useful, since the accuracy of all dimensions and quality of assembly are the main conditions for the normal functioning of a unit driven by a chainsaw.
Without going into technical details, we will consider the most interesting designs using it.
Options for homemade chainsaws
The first thing that comes to mind when you think about what can be done with a chainsaw is its use as a sawmill. Many developers had to split logs onto beams with this tool.
In this case, the log lies motionless and is neatly sawn along its entire length without wobbling or oblique seams. If you equip such a mobile carriage with four lifting screws, you can accurately set the thickness of the sawn timber.
A lightweight homemade snowmobile made from a chainsaw is more complex in design than a sawmill, since here you need to move the gas and clutch to the steering wheel, and also take care of the shock-absorbing suspension of the supporting frame.
To increase traction, a “traction” gear is placed on the caterpillar drive shaft, the diameter of which is larger than the size of the chainsaw drive sprocket.
There are usually no problems with the steering mechanism, since it is taken from a regular bicycle or scooter and modified so that the central axis moves the rods that turn the skis. The snowmobile engine power must be at least 5 horsepower, so it is better to use a Ural chainsaw for this purpose.
The winter line of homemade vehicles will be complemented by snowmobiles
from chainsaws, which are structurally simpler than a snowmobile. The driving force is provided by a large diameter screw, which directly rotates the gasoline engine.
Those home inventors who would like to make a backpack-type helicopter from a chainsaw should know the same thing. Such a machine will require not one, but at least two engines operating in a coordinated mode.
This vehicle is most often made for the sake of principle rather than practical use. The main driving force of its creator is the desire to test his strength as a mechanic and prove to others the original use of this cutting tool.
The basis for the design is usually my grandfather’s old Druzhba chainsaw and an equally ancient bicycle, with which you can carry out any experiments on converting the frame for mounting the drive.
Power is transmitted here through a gear pair using a bicycle chain, and the start of such a homemade product is reminiscent of preparing for cutting firewood.
Less common are more advanced models, the basis for which is a mountain bike equipped with reliable brakes and shock absorbers. This chainsaw moped is equipped with a gearbox with a gear ratio of 18:1 and a CVT transmission, which allows you to comfortably move on it at the speed of a regular bicycle.
This option for using a chainsaw is quite simple, since the task here is to transfer torque from the saw motor to the propeller. A homemade outboard motor does not need to install a transmission. For it you will need to make a reliable adapter on a lathe from the saw drive gear to the propeller shaft. The propeller can be used from a standard outboard motor.
It is difficult to make a full-fledged walk-behind tractor from a chainsaw due to lack of power and traction. But many home craftsmen were able to build a lightweight motorized cultivator based on it.
The design of such a machine is very simple: the motor rotates a pair of gears and transmits increased traction force to one drive wheel.
The chainsaw motor is no different from rotating the cutting chain or the auger mechanism of a snow blower. Here everything depends only on the design abilities of the creator and his ingenuity.
Using a Stihl chainsaw with a power of about 3 kW, you can easily build a good device for clearing an area of loose snow. To simplify the design, some craftsmen refuse to install wheels and use conventional sled runners.
The chainsaw asks for the sky
The most daring inventors have long been eyeing the possibility of using a chainsaw as an engine for an aircraft. However, this instrument is not strong enough to master airspace. Therefore, no one has yet succeeded in making a backpack helicopter out of one chainsaw.
This device is useful not only when building a fence or foundation from screw piles, but also during winter fishing, when you have to drill dozens of holes in thick ice.
A motor winch is a very useful device, because with its help you can not only easily pull out a stuck car, but also lift a heavy load to a height, pull a boat onto land or move a cut tree.
The camping power station is assembled on the basis of Ural or Druzhba chainsaws. It consists of a frame, an engine with a gear reducer, a control panel, a generator and connecting electrical cables.
Beavers are serious competitors of chainsaws in the wild.

How to make a winch from a chainsaw
For plowing, a chainsaw-driven winch has a number of advantages. The main advantage over a motorcycle engine is the speed of installation of the chainsaw. There is no need to design engine cooling, install a fuel tank, air filter, electrical equipment (switch), or wiring. Make a homemade exhaust system. Secure the muffler.
1 – chainsaw; 2 – gearbox; 3 – drum; 4 — drum control lever; 5 – frame; 6 – anchor.
Chainsaw attachment winch
The attachment or attachment is a reduction gear. If you remove the cover and look inside, you will see a whole series of different gears, small and large. With the help of which the number of drum revolutions changes depending on the number of revolutions of the engine crankshaft. In this regard, the load on the power unit is reduced. That's what we need in hard work.
The connection between the attachment and the chainsaw is made using a clamp and a stand. Due to this, the winch is compact and lightweight, easy to use during assembly and repair.
3 – drum; 4 — drum control lever; 5 – frame.
The torque, from the crankshaft, passing through the reduction gearbox, is transmitted to the shaft on which the drum with the cable is located. The drum has the ability to be connected and disconnected from the shaft. It occurs using a lever and special cams located both on the shaft and on the drum. We move it, use the lever towards the chainsaw to connect it, reverse it, and turn it off.
We selected material for the supporting frame of the entire homemade product. Old used water pipes and an unwanted metal bed. For ease of use, the frame is made in the form of a sleigh. During plowing, you do not need to lift the winch, you just need to move it.
It takes a lot of effort to cultivate the soil. Our homemade product turned out to be light, so it needs to be firmly secured to the soil to prevent spontaneous movement towards the plow. For this we installed a special anchor. Attached to the frame using a hinge. By pressing the anchor from above, special knives easily sink into the soil. Hold the homemade product firmly in one place. You can and should press with your foot, and pull it out with your hand using a special bracket.
8 — hinge; 9 — bracket; 10 - knives.
The control of a homemade winch is very simple. We only have two levers, one on the chainsaw and the other on the attachment. Plus anchoring and dragging towards an unplowed area. Even a woman can easily figure this out. BUT for all this to work you need:
- perfect clutch operation;
- trouble-free easy starting of the power unit;
- stable engine operation at idle speed;
- precise operation of the chainsaw starter.
Cons: Long-term operation of the power unit often becomes unstable. High fuel consumption compared to engines from light motorcycles Minsk or Voskhod.
How to make your own launcher for the T-40
A homemade launcher on the T-40 is certainly an attractive savings for agricultural workers or those people who work on tractors on their own plots.
Thus, to construct the mechanism, old chainsaws “Druzhba” or “Ural” are often used, which are now practically not used, but many people still keep them in their dachas.
So, in order to install a homemade starter, you must first cut the starter installed on the tractor almost in half, its shaft on which the winding is located. The “Star” attachment from the “Druzhba” or “Ural” chainsaw is welded to the sawn starter. In this case, you need to be careful and keep your distance.
The role of the starter bendix in this case is performed by a spring that holds the mechanism. So, when engaging the flywheel, this spring is compressed, and when the engagement stops, the part is released
It is important to remember that before starting the starter you must turn on the tractor compressor
Chains from mopeds are also used to construct a homemade launcher. At the same time, the fuel supply to the launcher remains the same as in the PD-8: diesel enters the launcher by gravity.
Making an angle grinder
An angle grinder is a multifunctional tool necessary for a number of jobs. Despite its availability and prevalence, craftsmen made an angle grinder from a chainsaw (a sample is shown in the photo below).
Assembling an angle grinder using a special device for a chainsaw goes like this:
- remove the chain and bar from the gasoline saw;
- install a pulley on the gearbox shaft;
- instead of a tire, they mount a special attachment, also with a pulley, after putting a belt on it;
- tension the belt drive like a chain;
- attach the protective casing;
- install the disc.
The entire process is shown in detail in the video below.
A self-assembled grinder-petrol cutter will help in performing many practical tasks. Its power is sufficient for productive work on concrete.
Generator
A chainsaw with a 2-stroke engine with a power of 2-3 liters is suitable for production. With. Electric motors from old washing machines are often used as electric generators. The combination of these devices makes it possible to obtain an output voltage of 220 V. The power of such a gas generator is sufficient for lighting, powering electrical appliances and tools, and household appliances.
- A bracket is made and the electric motor is attached to it. Install the resulting structure on the outer end of the chainsaw bar. At the same time they provide:
- perpendicularity of the electric motor axis to the plane of the tire;
- the location of the pulleys of both devices in the same plane.
- The output shafts of the engines are equipped with pulleys of suitable diameter.
- Put a belt drive on the pulleys.
- A device is made to regulate the speed of a chainsaw motor. A bolt is used, which is attached to the handle of the latter using a clamp. Tightening it leads to an increase in the number of revolutions, unscrewing it leads to a decrease.
- The external starting winding of the electric motor is supplied with 2 capacitors, which are designed for a voltage of 400-450 V and have a total capacity of 10 μF. Their connection is parallel.
Are old chainsaws still needed today?
Probably, many people have old chainsaws of the “Friendship” type lying in their sheds and storage rooms. For a long time it was a pity to throw away the saw, but it came in handy for making a drill
This saw has a fairly powerful and, importantly, low-speed engine. There should be no difficulties with mounting such an engine.
We install the fuel supply control handle on the upper (smaller) frame. The soil is very uneven in its structure - layers of varying density and viscosity, stones, roots, etc. The drill can jump off, suddenly increase speed, or move to the side, so we strongly recommend placing an emergency engine shutdown system next to the fuel supply control mechanism.
old chainsaw "Friendship"
Some old Soviet saws are quite large, which requires an increase in the size of the gas drill. Before starting work, consider whether it will be convenient to operate such a structure. Otherwise, the Druzhba, Ural and similar chainsaws are quite suitable for our task.
Moped with motor
All chainsaw crafts are distinguished by their practicality, but where would we be without it if the power unit is a real engine.

Happy chainsaw crafts to everyone and don’t get bored.
Auger machine
Do-it-yourself snow removal equipment for the home is a useful homemade product. To make a snow blower, you first need to study the mechanisms. The snow removal unit will consist of an auger, which is located inside a metal housing. This is a kind of rod or shaft along which a spiral surface is located. The shaft rotates due to the bearings and drives the spiral profile. A homemade snow blower, properly made with your own hands, will become an indispensable assistant in winter.
Single stage model
According to the operating principle, snow removal devices can be divided into two-stage and single-stage. The operation scheme of a single-stage apparatus is to “absorb” and dump snow. This is achieved by rotating the screw.
The working edge on the device can be smooth or serrated. The smooth one is usually used to remove loose snow, and the serrated one is suitable for a hard crust that has frozen over overnight.
Judging by weight, auger units are much lighter than rotary augers. Their disadvantage is that they are not self-propelled, so a person will always need to stand at the helm. Such a machine is a large shovel on wheels, which must be constantly pushed forward. Then she will rake up the snow and throw it in the designated direction.
The auger is driven by a gasoline or electric motor, which can be four-stroke or two-stroke. Such cars have become very popular due to their easy operation. Another positive aspect is their compactness.
Two-stage unit
The unit is designed slightly differently than the previous model. The first stage of the design ensures snow raking with an auger. The second stage will throw out snow through a chute. This is achieved using a snow rotor, which acts as a discharge impeller.
Such models are designed on the principle of a screw shaft with a serrated or smooth edge. Augers are made:
- in metal or rubber version;
- made of reinforced steel;
- made of rubber plastic.
The choice will depend on the purpose of the self-propelled vehicle.
The impeller of a two-stage model can have 3 or 6 blades. They are made from a variety of materials, depending on the severity of the work to be performed using the unit. The more complex the work, the stronger the material should be chosen.

Chainsaw attachment winch
Attachment or nozzle. This is a reduction gearbox. What can be made from a motor, how does this work, make a winch from a chainsaw. If you remove the cover and look inside, we will see a whole series of different gears, small and huge. home » household appliances » how to make a circular saw, a miter saw, a hand power saw with your own hands from an angle grinder, how to make a miter saw. With the help of which the number of drum revolutions changes, depending on the number of revolutions of the engine crankshaft. In this regard, the load on the unit is miniaturized. That's what we need in hard work.
The connection between the attachment and the chainsaw is made using a clamp and a stand. Because of this, the winch is small-sized and lightweight, comfortable to use during assembly and repair.

If you understand the brand of gearbox and its manufacturer, write in the comments. The gearbox is cylindrical.
Winch attachment for a chainsaw - installation procedure
If the owner of a chainsaw does not want to assemble the device himself, or he does not have the necessary skills for this, then he can buy a special device. It is a unit that includes a drum with a cable, a drive and a gearbox. The working mechanisms of the winch are placed in a shock-resistant housing that protects them from accidental falls.
The winch attachment for a chainsaw is easy to install and remove yourself. To install the device, a pipe is provided in its device, inside which a shaft is placed, which plays the role of a drive. To install the device, it is enough to remove the standard saw set of the chainsaw. After this, the shaft is connected to the motor. The winch body is secured by bolting.
When operating a chainsaw with an attachment, the motor creates torque and transmits it through a reduction gearbox to the drive shaft. He, in turn, begins to spin the drum with a metal cable. To stop the reel, the operator must turn the ignition switch to the "Off" position and turn off the engine of the garden tool being used.
The main advantage of the winch attachment is its small dimensions. At the same time, it is equipped with a fairly reliable cable that can withstand high tensile loads. Thanks to this, the device makes it possible to pull objects weighing up to 1–1.5 tons out of ravines or holes.
In addition, the nozzle has a fairly simple design. This makes it easier to independently maintain and repair.

Gas winch made from a chainsaw and gearbox
Hello everyone, in this instruction we will look at how to assemble a chainsaw-based winch with your own hands. Such a useful device can be used for various purposes, because it is mobile and runs on gasoline. The author uses it to drag logs from the ravine. This is very convenient and useful when preparing firewood, building materials and other things. Also, such a winch can easily be used as a lift, which will be convenient during construction work. For example, you need to lift several buckets of cement, this winch will easily cope with the task.
The author used a chainsaw as a motor. You will also need to obtain high torque for the winch. For these purposes, an old worm-type reduction gearbox from some equipment was used. All other materials are easy to find or make. So, let's look in more detail at how to make such a winch.
List of materials:
- chainsaw; — reduction gearbox; - bicycle spare parts; - Sheet steel; - corner; - steel pipe; - screws, nuts, etc.; — cable for control; - cable for winch.
List of tools:
- lathe; - drill; - Bulgarian; — welding; - screwdrivers, wrenches, hammer and so on.
The process of making a homemade winch:
Step one. Disassembling the chainsaw
Let's start by preparing the chainsaw. First of all, we need to remove the clutch and sprocket. To unscrew it, the engine needs to be fixed; for these purposes we need to remove the top cover and unscrew the spark plug. Insert a cord, a piece of leather or something similar into the spark plug hole. Now the engine will rest against the skin with the piston and will no longer turn. Using a special wrench, unscrew the clutch and remove the sprocket. An angle grinder wrench will do if the clutch is not tightened too tightly.
Step two. Drive sprocket installation
As a result, after installing the structure on the saw, we have a drive sprocket equipped with a clutch, which is very convenient.
Step three. Drive sprocket installation
The author fastens the pulley itself with three screws, two of them secure the pulley from turning in a circle, and another one is screwed in so that the pulley does not come off the gearbox shaft.
Step four.
Install the chainsaw on the gearbox Step five.
Protective shields Step six. Making a winch pulley
The winch pulley is needed so that the cable can be wound around it and the desired work can be done. To make it, we first take a piece of steel pipe of a suitable diameter so that it can be put on the gearbox shaft. Next, drill holes and cut threads for the screws. Using screws we will secure the pipe to the shaft; there is a groove there. The ends of the screws will need to be ground to the diameter of the groove.
Step seven. The basis
Also attach a cable to the winch, with which you can tie it to a tree, car, and so on. At the end of the cable, install a hook for quick attachment.
Step eight. Handle for control
Finally, paint the metal parts of the structure. When working in the forest, moisture will quickly cause the metal to rust.
Step nine. Tests
You can start testing the winch! We tie it to a tree, car or other reliable support. We tie one end of the cable to a log that needs to be pulled out of the ravine. Well, we wind the other end onto the winch and turn on the machine! Slowly adding speed, we ensure that the log begins to crawl towards you from the ravine. The author has made quite a few columns this way. In any case, it will be much easier than carrying them by hand, after which you get very tired and your muscles hurt. And to prevent a forester from catching you doing this, it would be useful to install a muffler on the chainsaw.

Advantages of a homemade launcher
Despite the fact that tractors are equipped with batteries, which, like in conventional cars, are capable of setting the car in motion, many users opt for installing a starter on the tractor. This is explained primarily by the fact that the launcher will not fail during frosts.
The battery may freeze and not provide the required number of revolutions to warm up the engine, and subsequently discharge very quickly. The starter can work uninterruptedly even in the most severe frosts, since it functions in a completely different way: the more the tractor driver turns the starter, the faster it heats up.
Another advantage of the launcher is its durability. Such equipment can serve the user for more than 20 years, even if it is not a store-bought unit, but a homemade one. But the battery may have to be changed more than once during the same period.
Finding out how to make a homemade launcher is quite simple. Since those who made the device with their own hands are happy to share their work on the global network with other users.
What determines the durability of homemade motorized winches?
The main factor that influences this is the build quality
Therefore, please pay attention to the following:
- reliability of the clutch of motorcycle tools;
- no problems with starting the motor part of the saw - slipping, unexplained shutdowns: the saw should run smoothly and hold idle and high speeds equally well;
- trouble-free starter - otherwise a minute’s work will turn into many hours of agony;
- the presence of safety systems, hooks, belts, which should help bring the structure to perfection.
Diagnose gasoline saws for malfunctions, and only then adapt them for homemade projects: this way you will ensure your safety and save time.
What is needed to make a winch?
Despite the simplicity of the initial design and ease of self-assembly, the winch designer will still need to prepare a certain list of parts and mechanisms. Their installation in the overall structure of the device will allow you to assemble equipment that will work as stably as possible and will not let the owner down at the most inopportune moment.
To assemble a winch based on a household chainsaw, the manufacturer will need:
- a fully serviceable and ready-to-use gasoline saw - domestic models Druzhba and Ural, as well as high-quality brand saws Stihl, Husqvarna, Patriot and Al-Ko, are very popular among assemblers. The main requirement for the engine is that its power must be at least 3 liters. With.;
- gearbox - this mechanism will connect to the power unit of the chainsaw and reduce the initial torque created by the internal combustion engine;
- metal pipes, couplers, brackets, steel sheets - needed to assemble the support frame and winch body;
- drum and reinforced metal cable;
- steel hook;
- cam metal clamps;
- fastening clamps;
- lever for controlling the winch.
It is best to pre-coat metal and steel components with a primer and several layers of paint. It will protect parts from the formation of pockets of corrosion and rotting caused by regular use of the device under conditions of constant exposure to moisture.
Preparing for self-assembly
Immediately before making a homemade device, you will need to study the drawings. The diagrams must indicate the mounting capabilities of all parts used, as well as their dimensions.
To work you also need to first prepare:
- engine from a household chainsaw complete with fuel tank, carburetor and drive. The required petrol engine power is from 3 liters. With. and higher;
- gearbox - this mechanism is necessary to reduce the generated torque that the engine generates;
- drum - you can find it at the old equipment market. An element from an old winch or a homemade device made from sheets of forged steel will do;
- cam clamps - required to fix the drum in a stationary state;
- lever - needed to turn the engine on and off;
- clamps - with their help the gearbox is connected to the internal combustion engine of the chain saw.
A winch driven by a chainsaw must be equipped with a reliable metal cable that can withstand significant tensile strength and abrasion.
