Impact wrench “Meat Grinder” with torque boost

Automobiles, especially trucks, buses or special equipment, often use fairly large threaded connections. Almost every driver has encountered a problem when a bolt (or nut) is so “stuck” that unscrewing it is a serious problem, even if you have the appropriate head and a considerable extension. In such cases, a manual meat grinder comes to the rescue, with the help of which unscrewing the fasteners is much easier.

Advantages and disadvantages

Almost all the advantages of this design are associated with the multiplier, which converts and also amplifies torque. It is worth noting the following important features of the impact wrench.

• The design itself is quite simple, but at the same time durable and reliable.
• Using a “meat grinder” wrench, the fasteners can be unscrewed very smoothly. In addition, this can be done with those parts that ordinary wrenches cannot handle.
• This impact wrench is small in size, making it very convenient both in operation and in transportation.
• He is autonomous.

• Working with such a tool is quite convenient, because a person uses very little effort, and the work moves very quickly.
• Repair work can be accelerated, which saves significant time.

Many consider the heavy weight of the impact wrench to be one of the biggest disadvantages. However, this is not entirely correct, given that very strong metals are used in the manufacture of the tool, and therefore the weight increases. Accordingly, its strength will be several times greater. In addition, those people who do not adhere to the rules for using the tool believe that the high power of the unit is also a disadvantage, because you can simply break the thread. Drawing a conclusion from all of the above, it can be noted that if you follow all the recommendations, you will not have to face the disadvantages of the impact wrench.

Be careful: choose wisely and to your advantage.

How to choose a mechanical multiplier impact wrench

The main indicators of any manual impact wrench are: gear ratio, torque, the size of the square for the attachments and the dimensions of the tool itself. The gear ratio of most “meat grinders” is 1:56, which means that for 56 full rotations of the handle, the head of the impact wrench will make 1 revolution. The speed is too low for complete unscrewing, so this tool is used only to loosen the fasteners and then turn it with a regular wrench or manually. There are 2-speed models where you can change the gear ratio to 1:3. In this case, it will be enough to switch the mode after loosening and completely unscrew the nut without removing the impact wrench.

The torque indicator determines how hard the wrench will apply pressure to the nut. This indicator is measured in newton meters (N m). Depending on the type of work, you should select a tool with suitable torque. For example: to loosen the wheels of a passenger car, 200 N m will be enough, while on a truck this figure should be at least 1000.

The size of the fastener that can be used with this tool depends on the size of the connecting square. For example: for fasteners with a size of 10 to 16 mm, a 1/2 inch square is suitable, when with larger nuts (20-50 mm) you can only work with a 1 inch square. Accordingly, a hand wrench for cars can have a square of 1/2 inch, and for trucks this figure should vary from 3/4 to 1.

Hand wrench. Trucker's "meat grinder"

Automobiles, especially trucks, buses or special equipment, often use fairly large threaded connections. Almost every driver has encountered a problem when a bolt (or nut) is so “stuck” that unscrewing it is a serious problem, even if you have the appropriate head and a considerable extension. In such cases, a manual meat grinder comes to the rescue, with the help of which unscrewing the fasteners is much easier.

Advantages and disadvantages of manual impact wrenches

Since the design is based on a multiplier that converts torque and amplifies it, the advantages of the tool are associated with this. The following are the advantages that a mechanical impact wrench has:

• simplicity of design and, accordingly, high reliability;
• smooth but powerful unscrewing of fasteners;
• complete autonomy;
• relatively small dimensions;
• ease of use, saving effort;
• simplifying repairs and saving time.

The rather large weight of a manual impact wrench is sometimes cited as a disadvantage, but it should be understood that the weight is due to the fact that reliable and durable metals (alloys) are used in the production of impact wrenches. It is clear that it is quite difficult to make a tool as reliable as possible, but at the same time lightweight. In principle this is possible, but the price of a manual impact wrench would be too high. In addition, excessive power is sometimes considered a disadvantage, since if used carelessly, the multiplier can easily break fasteners or break threads

This drawback is also very conditional, since caution and thoroughness are necessary when working with any tool, even the simplest

Several types of hand-held impact wrench are produced. The thrust tenon can be made integral with the body or moved along it. If the stop moves, then in certain positions it can be secured using a special mechanism. In addition, there are devices with a bearing or a gearbox, the shafts of which rotate on bushings. The price of a bearing impact wrench for trucks is higher, but it is considered more reliable, convenient and durable. Two-speed multipliers are also available. Gear ratios differ; there are regular or extended impact wrenches.

Design differences

Depending on the design features, all impact wrenches are divided into several types. Thus, the thrust lever can be movable or stationary. In the latter case, it will move along the body, but at the same time it can be fixed in the desired position using a special mechanism.

Based on the design of the multiplier, a load wrench can be differentiated with a bearing or with a bushing. Tools equipped with the first elements have the index “P” in their names. The price of these devices is higher, but at the same time they are characterized by a high level of reliability, durability and comfort during operation.

Models with bushings are simpler in design and do not have the same durability as a “meat grinder” equipped with a bearing. The price is also low. You can purchase a tool from 2500 rubles. Models also differ in the number of speeds. Devices with a ratio of 1:56 or 1:58 have one or two speeds. A reduced gear ratio of 1:3 is available.

Features of service. Prices

Like other types of tools, a manual meat grinder requires careful handling for long and successful operation. In addition, the use of any mechanical device must meet certain safety requirements. There should be no sharp edges, chips or cracks on the body and elements of the multiplier (handle, heads). Excessive work loads are also unacceptable. The socket head and handle must be fitted tightly and have no play. Heads that are worn out or have a broken hexagon cannot be used. Before use, make sure that the head is fully seated on the fastener until it stops.

To extend the service life and keep the tool in working condition, timely maintenance and repairs are necessary. In addition, even if the manual impact wrench is fully operational, the conditions for its storage must be observed. It is necessary to ensure that water and dirt do not get on the impact wrench, and if they do, the tool is cleaned as soon as possible. The device requires periodic lubrication. The price of negligence is failure at the most inopportune moment.

Prices for manual torque boosters can vary greatly. If we consider impact wrenches for trucks, their price ranges from 2 to 10 thousand rubles. There are multipliers used for industrial or construction purposes; their cost can range from 80 to 200 thousand rubles.

A standard mechanical meat grinder, familiar to truck drivers, does not take up much space in a truck or auto repair shop. It is relatively inexpensive, reliable and works for many years.

Types and types of devices

A truck impact wrench is a tool for a narrow application. However, the amount of work that can be done with it is quite impressive. There are several types of this equipment. So, according to the principle of action they distinguish:

• pneumatic;
• hydraulic;
• electrical;
• mechanical devices.

Pneumatic equipment has the most compact dimensions, as well as an average level of speed and accuracy.

These models are indispensable in workshops and service stations.

Hydraulic tools have the highest efficiency, do not vibrate during operation, have a huge service life and high wear resistance. This is rather stationary equipment, which is to some extent their disadvantage. The huge size makes this device a purely professional tool.

Electric models are high-speed, highly accurate, and vibration-free. There are mains devices and battery-powered ones. All this equipment is very effective, but if you need to change a tire on the road on a huge truck, then, alas, mobile electric models cannot do it.

The best electric impact wrenches

Electric models of impact wrenches have found application in service stations, furniture production and other industries. Designed for work with metric fasteners. The operating principle of the tool is based on converting electricity into the rotational movement of the working body and imparting additional shock impulses to it.

Manual impact wrench “meat grinder” for trucks

In a truck driver's toolkit, a torque wrench or “meat grinder” is very popular. Such a tool can greatly facilitate the unscrewing of wheels, stepladders, springs and other bolted connections, even those that are “stuck” and under heavy load. Far from civilization, a compact impact wrench can be of enormous benefit, saving the driver time and effort.

Motorists who have not encountered a hand wrench often ask the question “How to unscrew a nut on a wheel.” This process is extremely simple, but has certain features that must be taken into account when using the tool. The first thing to remember is that a manual mechanical impact wrench turns in the opposite direction (if you turn the handle clockwise, the bit and nut will go in the opposite direction). It is also necessary to monitor the location of the stop (to unscrew/tighten the left and right wheels, its position changes). The exact information is given in the table below.

In addition to manual models, electric impact or impact wrenches can be used to change tires on the road. They are quite powerful, but less reliable, since they have a more complex mechanism and are dependent on battery charge. Typically, such impact wrenches are used for passenger cars, but many models can also handle large-sized equipment.

Methods of use

Working with impact wrenches is simple - everything is very intuitive and understandable even to those who are encountering this for the first time.

But there is one small subtlety here that you will have to get used to. The handle rotates in one direction and the head in the other. If you turn the handle clockwise, the head will rotate counterclockwise - this must be taken into account during operation.

To get started you need four simple steps:

1. Assembling equipment.
2. The head is put on the nut.
3. The thrust lever is installed closer to the nut.
4. They rotate the handle, and when the nut has been removed, you can reconfigure the mechanism to a lower gear ratio.

There is nothing innovative about this tool, but it can greatly facilitate changing a wheel on the road, saving time, without stripping the threads or damaging part of the hub.

So we found out what a manual truck impact wrench is and how it is used.

Kinds

Not everyone needs a manual impact wrench for trucks, but it makes the job much easier for owners of large vehicles and service station workers. There are several types and types of such tools. They are divided into shock and non-impact, electric and battery-powered. And also for tools with and without gearbox. To decide for yourself which impact wrench you should choose, you need to find out basic information about all its varieties.

Electric

Such models are more suitable for domestic use. They work from the network, weigh little and at the same time do their job well. Most often they are purchased for small service stations, tire service, and also for personal servicing of passenger cars. However, more expensive and powerful tools may even be suitable for trucks. True, a powerful and good model will cost many times more.

Rechargeable

These tools are widely used and are popular with many drivers. Cordless impact wrenches come with different parameters, so you should choose them based on the work you have to handle.

The battery in such designs is powerful enough, which makes it possible to change an entire set of wheels at once, even on a truck.

However, when choosing, you need to pay attention to how long the charge can last.

This is especially important for truck drivers, since a weak battery may die on the road

Pneumatic

A fairly durable impact wrench with excellent torque ratings. However, the disadvantage of such models is the need to constantly connect them to the compressor. Most often they are used for work in large car dealerships, as well as in production.

Mechanical

One of the most reliable options among all is considered to be a geared manual impact wrench “meat grinder”. He can tighten any necessary part without outside help. That is, he will not need a battery, compressed air, or electrics. Such a tool is often called a wheeled tool, as it is used in tire fitting for trucks. Among his “colleagues” he is the most popular among truck drivers due to his reliability.

Hydraulic

These impact wrenches have great accuracy and also have high torque. Most often they are used to work with very large fasteners precisely because of this. Such tools practically do not vibrate, in addition, they are quite durable. However, they are not suitable for work in tire fitting. Perhaps as an additional tool, which is used in the most difficult cases.

Hydraulic impact wrenches can be divided into two subgroups: snap-on and cassette. The first ones are used in the most difficult cases: when the nut is too tight or the fastener is covered with rust. In this case, it is a powerful hydraulic impact wrench that helps solve the problem.

Hydraulic cassette impact wrenches can also “save” you in a difficult moment. They allow you to treat hard-to-reach places. This is facilitated by their small diameter and flat shape.

Test results

The cheapest impact wrench (Bort BSR‑12) did not survive to the end of the tests - the plastic gear turned. The most expensive one, Makita TW140DWAE, turned out to be very weak: its efforts were not even enough to unscrew the wheel fasteners. “Zubr” delivered a torque about half of what was promised: for most cars this should be enough. The same can be said about Bort BSR‑12X.

When choosing a non-professional impact wrench, we recommend focusing on the torque it develops. Even if the impact wrench produces only half of the declared 350 Nm, in practice this will be enough to repair any passenger car. If you bought an externally powered impact wrench, we strongly recommend connecting it not to a standard 12-volt outlet, but through an adapter directly to the battery terminals. Otherwise, you will go broke replacing fuses.

Scope of application of a manual impact wrench

Most often, a manual impact wrench with a gearbox is used in the industrial sector when working with large-sized structures. This tool is popular in auto repair shops, construction sites, shipbuilding and the railway industry. Widely used in plumbing and other work where you have to deal with massive or loaded threaded connections.

In everyday life, a manual mechanical impact wrench “meat grinder” is used much less frequently and has a less wide range of applications compared to production. Typically, truck drivers purchase this tool to be able to quickly change a tire while traveling. Also, this device may be needed if you have started a construction project in which there are many large nuts and bolts. A mechanical impact wrench is not an essential tool for the home, and in most cases can be replaced with a regular wrench or wheel wrench.

Purpose of the mechanical device

Any truck driver knows that the process of unscrewing the wheel nuts that secure the wheel to the hub is much more difficult and difficult than tightening it. The wheel can be installed very quickly and easily. A simple wheel wrench will be enough for this. If you need to remove it, then to unscrew the wheel nuts, you need to use a long piece of pipe and the weight of the driver, since the nut often sticks almost tightly to the stud.

The reason for this lies in corrosion processes and the design features of the connection, or more precisely, in the thread profile. A small groove is formed between the nut and bolt, into which moisture freely penetrates.

Often, attempts to remove the disc and unscrew stubborn wheel nuts only lead to broken studs and the need for more serious repairs than planned. Trucks especially suffer from this.

The fasteners turn sour much faster, and there are much more of these nuts on the wheels. And to facilitate the process of removing and installing disks on trucks, it is worth using a mechanical impact wrench.

This tool has long been appreciated in the engineering industry, on the railway, and various construction works, but only recently began to be used for car repairs. In a very short time, this device was able to gain great popularity among drivers. And since it can be purchased at an affordable price, it is used by many drivers who drive on the roads of the country.

Characteristics

The “meat grinder” impact wrench is a very simple design. It is based on a cylinder-shaped body. It brings all the parts together and also ensures their full interaction. Most often, such a housing is made of polymers or metal (steel). However, in some cases it can be made from combined materials.

Inside it is a planetary gearbox. On its main part there is also a drive shaft, at the end of which there is a square handle. The other part houses the output shaft. It is on this shaft that all heads are installed so that you can work with fasteners. The impact wrench also has a lever with which you can stop the rotation during operation.

One of the main characteristics of such a tool is the gear ratio of the planetary gearbox or, in other words, the multiplier. It serves to convert torque. It is driven by a handle, which is why it is called a “meat grinder”.

Most often you can find impact wrenches on sale with a multiplier ratio of 1 to 56 or 1 to 58. The torque should be from 2700 N*m to 3400 N*m. In addition, the wrench comes with two heads that can unscrew or tighten nuts from 27 to 58 millimeters.

Operating principle of a meat grinder

The design of this tool is quite simple and is a planetary gearbox assembled in a metal case. Active rotation of the handle is transmitted to the output shaft, while the tool head rotates much more slowly than the handle rotates, but the force transmitted to the bolt or nut increases many times. By increasing the torque, a manual meat grinder can cope with fasteners that are almost impossible to unscrew by hand. For trucks, buses, tractors, and other large equipment, having such a device can be very useful.

Externally, a manual impact wrench looks like a metal cylinder with a stop leg (thrust spike) extending from it at an angle; all the mechanics are assembled inside. There are two square end switches left on the outside - the handle is put on one, and the head that directly rotates the fastener is on the other. The tool is completely mechanical and does not require access to electricity, compressed air or anything like that. Accordingly, you can use it in the field, on the road. Truck drivers who regularly go on long, long trips have come to appreciate the impact wrench, many of them carrying it in their car all the time.

The manual meat grinder is very easy to use. The head should sit tightly on the square and nut, the handle on its shank. The thrust spike is pressed tightly against the surface of the wheel rim and rests against the adjacent nut. It should be remembered that the rotation of the handle and the nut are usually directed in different directions. After the fasteners have been broken off and have begun to rotate more easily, it makes sense to remove the impact wrench, install the extension and finish unscrewing by hand. When tightening nuts or bolts using this tool, you must be very careful and careful. Due to the fact that the handle force increases many times, there are frequent cases of threads turning and pins breaking.

What is a manual impact wrench

A hand-held impact wrench is a powerful tool for specific tasks, but despite its narrow focus, it can facilitate many types of work. Essentially, this is an advanced analogue of a wrench, working on the principle of amplifying torque. From assembling furniture to unscrewing car wheels, a wrench will help almost anywhere there are threaded connections. Despite its compact size, it can easily tighten or loosen even the most impressive connections.

In appearance, a manual impact wrench resembles a meat grinder, which is why it received this nickname among truck drivers. Without going into details, a mechanical impact wrench consists of a lever, a multiplier, a stop and a chuck for bits. Inside the housing there is a planetary gearbox, which can increase the rotation force up to 80 times. To withstand heavy loads, the device mechanism is often made of durable alloy steel.

Main advantages

If you have personal experience with similar tools for loosening bolts and nuts, be sure to leave reviews. Comments are open and we are always ready for dialogue.

When choosing any tool or equipment for a machine, such as a hydraulic jack, the commonly used torque wrench or our manual mechanical impact wrench, consumers are interested in the question of its benefits.

Mechanical meat grinders have the following advantages:

• Smooth operation. Mostly bolts, nuts and studs break because the user distributes the load and force unevenly. The design of the meat grinder eliminates this problem;
• Physical fatigue. The principle of operation of the amplifier is aimed at minimizing the applied force, but at the same time ensuring the unscrewing of the heaviest fasteners;
• Time for repairs. This tool helps save a lot of time. This has been proven in practice;
• Price. The cost of manual tools with a gearbox is noticeably lower compared to electric, pneumatic and other impact wrenches;
• Versatility. The device can be used not only for car maintenance, but also in everyday life;
• Compactness. The dimensions are really small, which means there is no need to free up space in the garage. The meat grinder will easily fit on any shelf or drawer.

As for the disadvantages, the main disadvantage can be considered weight. But this is a fairly minor disadvantage that is worth sacrificing for the sake of other advantages.

Whether to choose such a tool or not is up to each individual.

Tips for selection and operation

In order to be able to unscrew the nuts even on the road, it is best to use a wrench with a mechanical device. When choosing, you must carefully study its characteristics so that they fully meet the necessary requirements.

• In order for the impact wrench to last much longer, it is necessary to test it, be sure to lubricate it with oil specially purchased for this purpose, and also check every detail of the tool.
• After this, you need to completely assemble the impact wrench. To do this, you need to put the head on the nut, and install the thrust lever as close as possible to the nut itself.

Next, you can begin to rotate the handle and do this until you manage to tear the nut out of place. After this, you need to rebuild the tool itself at a lower speed. After testing, you can begin any work that is feasible for the impact wrench.

• Do not forget that the impact wrench needs to be looked after, like any tool.
• It is also necessary to remember about safety precautions. You should definitely make sure that there are no cracks, sharp corners, or even sharp edges on the body itself, as well as on all elements of the multiplier.
• Do not allow high loads when working with the tool. If you need to work for a long time, you can stop temporarily and let the tool rest.
• It is necessary to ensure that the handle itself sits very tightly.
• If the hexagon is broken, under no circumstances should you use such a tool.

To extend the life of the impact wrench, it is necessary to carry out timely inspections and repairs. It is better to do this in specialized salons, so as not to damage the instrument yourself. All rules for storing the product must be followed. That is, make sure that neither water nor dirt gets into it. But if this happens, you must immediately remove all dirt or wipe it dry with water.

In addition, immediately lubricate all parts so that they do not become rusty. When choosing a suitable tool, you should also pay attention to such a parameter as torque. After all, if you choose the wrong model, the nuts will be tightened tighter than necessary.

Considering different types of tools, we can conclude that a “meat grinder” impact wrench is best suited for trucks. It is not only easy to use, but also quite powerful. In addition, the tool will help you cope with any situation that happens on the road. It can also be purchased for tire fitting work.

As for the brand. If you have read the material about jacks, you should know that the basis for selection is not the name or status of the manufacturer, but the technical characteristics that meet your requirements.

At the same time, I in no way support the purchase of cheap Chinese instruments and all kinds of counterfeits. Their main danger is that the stated characteristics may not actually correspond. Working with such meat grinders is potentially dangerous.

Therefore, first decide on the required parameters. And only then look for which of the leading or well-established manufacturers produces a manual impact wrench that satisfies all your requirements. This is the perfect recipe for finding the right tool.
