What is a rokhlya: photo, description, dimensions, weight, load capacity

Warehouse facilities are necessary for the coordinated and efficient operation of a company engaged in the production or sale of various goods. One of the main assistants in the warehouse is a hydraulic rocker, which allows you to move voluminous and heavy cargo.

When you need a hoist, not everyone knows how to choose it, especially since today many brands offer to buy lifting equipment.

You can purchase a hydraulic hoe at a reasonable price in the MD-Progress online store. It is only important to take into account some of the operating features of this product, and also to know what characteristics to pay attention to.

What does it mean

Until the sixties of the twentieth century, loaders worked in warehouses, manually carrying and lifting heavy loads onto racks. Labor productivity was very low. It was impossible to quickly unload goods that weighed more than 1 ton. Therefore, at the end of the forties of the twentieth century, foreign companies invented and released the first models of rokhli, which quickly gained popularity all over the world. Today, large warehouses, industrial areas and shops are filled with devices of various modifications and manufacturers from different countries.

The global market presents equipment with a variety of functional features:

• • With low and high load capacity from 2 to 5 tons.
• • With small or large villas.
• • With single or double wheels.
• • Lifting with legs.
• • Electrically driven.

Recently, products with improved designs have been produced with electronic scales and label printers.

Advantages of using pallet trucks

It’s hardly worth talking about how compact warehouses are sometimes made. Rokhlya has a number of important technical advantages that make it simply irreplaceable in use:

• Ease of Management;
• the ability to move cargo of any type (barrels, pallets, pallets, rolls, etc.);
• high degree of reliability (there is simply nothing to break);
• silent movement.

Initially, the cart may have stock wheels installed. But the owner, if he wants to get a silent wheel, must choose wheels that are best suited to the floor covering in the warehouse.

For example, in warehouses where there is a risk of spilling chemically active products, self-leveling floors coated with crumb rubber are often used. To operate the trampoline on such floors, you will need specialized wheels.

Hydraulic rokla or rokhla: what is the correct name?

In the sixties of the twentieth century, the name came from the Finnish company Rocla Oy. Models from this manufacturer began to arrive in the USSR and were sent to warehouses to help auxiliary workers, who found it easier and simpler to pronounce the word “rohlya” than “hydraulic trolley.”

Historical reference

Finnish manufacturers did not have time to produce the required number of fork carts, so the Soviet Union entered into contracts for the supply of equipment with Bulgaria. Until the collapse of the USSR (1991), Bulgarian, Skladova Tekhnika, Yantra, Simetro imported transporters.

In the early 90s of the last century, models from other countries, such as Denmark, England, Italy and Germany, began to arrive in the Russian Federation. But Russia had to abandon their goods due to the high cost.

At the beginning of the 21st century, major changes occurred in the world economy, and European companies had to replace the production of simple hydraulic carts with more high-tech units. And the production of old equipment was established in Asian countries where there is cheap labor. The PRC has also organized its own concerns. Therefore, the price of products varies greatly and depends on the supplier.

Forklift Brands Today

When choosing and purchasing equipment for loading goods, you should pay attention not only to the cost, but also to the country of manufacture. Defective products are often found when counterfeiting well-known European and American brands. But if the equipment passes the quality control department and is controlled by the shareholders of famous companies, then it reaches the market without complaints from buyers.

For example, the Chinese company Noblelift Equipment, together with the Americans, produces the NOBLIFT model, which will be much cheaper in cost than a similar product from the USA.

We will show you the percentage of transporters purchased by different manufacturers:

• • 20% of consumers purchase carts from China and other Asian countries, as they are attracted by the very low price. Grost is the most popular.
• • European models Lema Engineering, Otto-Kurtbach were in first place in demand (70%) due to high quality and low cost.
• • Famous products from world brands Rocla, Jungheinrich, Pfaff Motion, Yale, BT are available only to ten percent of consumers.

The use of a hydraulic trolley in building a house and renovating an apartment.

Many people think that a hydraulic pallet truck is only needed in industrial facilities, warehouses and shops. But that's not true. This tool is also successfully used to facilitate labor on construction sites and repairs. Let's give a few examples.

If you are renovating an apartment yourself, then such a cart can help you out with:

• rearranging furniture,
• moving bags of plaster or cement,
• aerated concrete blocks, etc.

And when building a house, a hydraulic trolley will also help move pallets with building materials not only along the “building spot”, but throughout the entire site. To do this, you should get a couple of metal sheets. By shifting them one by one, you don’t have to worry about surface unevenness that interferes with the movement of the cart.

Thus, you can freely move, for example, boulders for a barbecue or an artificial pond on the site.

The simplest hydraulic carts are not expensive (about $200) and weigh little (50-60 kg). This allows almost anyone to purchase them.

Where and how to apply

The transporter with a small carrying capacity has proven itself to be excellent for moving goods in large vehicles.

In the video we will show how rocla is used:

Advantages of warehouse equipment:

• • Use in all weather conditions. Rohlya is intended for work indoors and outdoors at air temperatures down to -50 degrees.
• • Low cost per product allows you to purchase equipment for any organization.
• • With proper use, the cart can last from 8 to 10 years.
• • Maintenance is simple and does not require special technical knowledge.
• • Problems can be corrected right at the workplace (no need for a specialized workshop).
• • The load capacity of the rokla is from 2 to 5 tons.
• • Thanks to its dual wheels, it can be used on uneven floor areas.
• • Small dimensions allow you to work in narrow corridors, small rooms, and vans where large technical equipment cannot reach.
• • With the help of a hydraulic system responsible for loading operations, even a woman will be able to operate the warehouse apparatus without the use of physical force.

What is rokhlya? Why does she even need it? Guide to Pallet Trucks

Let's start with the main question. What is rokhlya? This is a conventional manual hydraulic pallet truck for moving loads on pallets. In fact, “rokhlya” is a slang or “folk” expression, derived from the name of a Finnish manufacturer of warehouse equipment, including hydraulic trolleys, very popular in Russia in Soviet and post-Soviet times.

Let's take a closer look. Pallets or pallets are used everywhere for transporting goods. But heavy cargo on pallets requires special additional means for convenient and easy loading, unloading and moving.

The most common and widespread equipment for such operations is a manual warehouse pallet truck or pallet transporters. While all pallet trucks are essentially designed to achieve the same goal of facilitating freight handling, they can vary significantly in their design, underlying mechanisms, and applications. Let's look at the most basic types of pallet trucks and their purposes.

1. Manual hydraulic pallet truck (rafting).

The hand-held pallet truck, or pallet truck, is perhaps the most widespread and frequently used warehouse equipment in the world. Here, the loader manually lowers the forks of the cart using a built-in jack and pushes them under the pallet with the load to move it from its starting point, lift it and move it to another location. Hand trucks are cheap and easy to operate and can be easily carried into trucks or other vehicles. Cheap nameless carts from Asia are not expensive, but in essence they are almost a one-time solution, until the “first breakdown”. High-quality hand pallet trucks from reputable brands usually have safety valves and adjustable pump covers to ensure their maintainability and, accordingly, a longer service life, as well as high-quality steel and wear-resistant paint coating. Hand pallet trucks are often used and are especially popular in grocery stores and small warehouses - as the last link in the delivery of goods, firstly because of their low cost and availability, and secondly because of their small size and ease of operation. Their flat and durable forks provide good stability for the loads attached to them. Simplicity of management allows any warehouse employee to work on them, without prior training. Hand trucks usually have a lifting capacity of 1 to 3 tons, in rare cases up to 5 tons. They can also differ in the length of the forks (from 0.8 to 2.5 meters) and the height of the fork profile in their lower position.

The electric trolley is a self-propelled pallet transporter.

A modern version of a manual hydraulic pallet truck is an electric self-propelled pallet transporter (self-propelled electric pallet truck, electric pallet truck). This trolley is a battery-powered version of a manually operated hydraulic trolley. The electric self-propelled pallet truck is controlled by buttons on its handle, and the operator mainly uses the handle of the truck to control the direction of movement. These trolleys are usually equipped with a powerful motor wheel and an electric lift, which helps the user to easily load and unload cargo. This type of pallet truck requires less effort on the part of the loader because he does not have to manually pump and push on the handle to lift and move the load. A powerful electric drive allows you to move loads at a speed unprecedented for a walking loader and roll it up large ramp slopes. The productivity of self-propelled transporters is many times greater than that of hand trucks. Their management does not require much physical strength. More and more companies from small to giants are choosing self-propelled electric carts over a fleet of conventional manual ones. There are professional versions of self-propelled carts, equipped with an operator platform or even a cab. The carrying capacity of self-propelled trolleys ranges from 1 to 3 tons.

Hydraulic scissor trolley

The scissor hand pallet truck is equipped with a mechanism in the form of crossed scissors - hence the name "scissor" - located under the pallet forks. This mechanism helps to effectively lift goods placed on the trolley to a great height of up to 1 meter. High quality scissor lift carts are very reliable and feature a patented safety system on the handle. They are usually designed for loads weighing up to 1000 kg. These carts make work easier, help prevent back injuries and fatigue from heavy lifting, and thus increase overall work productivity. This type of trolley is very versatile, combining the capabilities of a trolley, a stacker and even a lifting table. There are professional versions equipped with an electric drive for lifting the forks of the trolley.

Trolley for transporting pallets equipped with scales

Hydraulic hand and sometimes self-propelled pallet trucks can be equipped with built-in scales, which help factories and warehouses not only transport goods, but also weigh them at the same time. Budget carts usually have a weight sensor that is not built into the fork design. The disadvantages of this solution are obvious - inaccuracy of weighing and dependence of the results on the centering of the load and the surface level. High-quality carts are equipped with built-in sensors, which are more accurate and reliable. The measurement accuracy of such carts can reach = - 100 grams per several tons of weight. Many manufacturers also provide pallet trucks with scales that have a rechargeable battery and a tare function that automatically sets the scale to zero when the truck is at rest. This feature greatly increases the accuracy of the scale. Some professional versions add a mobile printer for instant output and printing of weighing results.

Trolley for roll materials

Roll material cart or hydraulic spool cart is an original type of hydraulic cart that specializes in transporting roll materials, including fabric rolls and heavy paper rolls. Typically, the loader places the roll on a dolly to make it easier to transport. Good roll carts are corrosion resistant and easy to handle due to their light weight and maneuverability. The main feature of such carts is their special cone-shaped forks, which are capable of very securely holding a heavy roll or reel, preventing it from rolling away.

Stainless steel hydraulic trolleys

Stainless steel is always a preferred alternative to other cart materials such as iron, which are susceptible to erosion and rust over time. That's why a stainless steel pallet truck is a great long-term investment for businesses with harsh environments in the equipment area. Their basic design simplifies maintenance and operation. Due to the steel's resistance to extreme temperatures, these pallet trucks are widely used for moving goods in cold storage warehouses. Easy cleaning and the absence of oxidation of the body metal also allows them to be used in industries that are particularly demanding on cleanliness (food, chemical and pharmaceutical industries)

Hydraulic all-terrain trolley (for rough terrain)

There is a separate type of hand trucks - hydraulic all-terrain trolley or off-road trolley. Such carts are simply irreplaceable for working in open areas, construction sites, agricultural enterprises, etc. Such carts are equipped with large pneumatic wheels and specially designed forks.

Pallet transport trolleys are an extremely important and indispensable type of equipment for businesses and warehouses. Since carts are available in various subtypes, shapes and sizes, differing not only in design but also in materials, the best decision before purchasing them would be to carefully study the pros and cons of carts of different price categories and manufacturers. And only after that is a balanced decision to purchase.

In conclusion, we traditionally remind you: the Madlift company offers you a wide selection of high-quality warehouse trolleys, both manual hydraulic and electric self-propelled, for any task and budget. Contact us, if necessary, our managers will help you with your choice, advise and select the best options.

What does the transporter consist of and how does it work?

The components are very simple and understandable to the average person:

• • Metal forks that lift and lower weights on pallets.
• • Handle for controlling the movement of equipment.
• • Single, paired wheels made of metal or polypropylene.
• • Foot or hand lever for raising and lowering the product.
• • Hydraulic apparatus consisting of a drive, a chrome-plated piston and an overload valve.
• • Lifting mechanism.
• • Foot or hand brakes.

The operating principle of the lifting device is similar to that of a conventional jack. It is necessary to pump the handle with smooth movements to raise the cart to the required height. Usually 6-7 movements are enough for this purpose. After this, the villas are raised to a maximum value of 0.22 m. This is enough to transport large bales over a short distance. All manipulations are performed using a pen. Also, the rotation of the villas depends on the lifting console located in the movable body of the lever device. It helps to grasp the load located in the transverse direction.

Modern technological processes have helped improve the design of the warehouse wagon. Now, with its help, you can find out the weight of the goods, change the center distance between the grips of the villas and tip over the products.

Hydraulic diagram of the rover

The hydraulic system control device is a pump and a three-position plunger stroke switch built into the handle (up, down, neutral). For heavy-duty hydraulic trolleys, the drive can be foot driven.

The handle is usually rubber-lined, spring-loaded, and self-adjusting to specific operating conditions. The pump body is manufactured using precision casting methods, which minimizes possible leakage of hydraulic fluid. The actuator element of the hydraulic drive - the piston - is made of high-quality structural steel, undergoes hardening heat treatment and has a protective chrome coating. The plunger is protected from contamination of the gaps by a hinged cover, which protects the surface of the plunger rod from condensation if the hydraulic breaker is operated alternately, indoors and outdoors. The hydraulic drive is protected from overload by a safety valve.

The hydraulic circuit of the ram works like this. The forks are inserted into the gap between the surface and the bottom of the pallet. When the handle swings, the piston begins to supply working fluid to the lower part of the cylinder, causing the rod with the plunger to rise upward. During the reverse stroke, the flow of liquid into the cylinder is prevented by a safety valve, which is activated only when the forks are overloaded by the tipping moment. Upon reaching the required height of the pallet with cargo, the hydraulic drive control handle is moved to the neutral position, after which the load can be rolled in the required direction. The pan is lowered by turning off the control valve, which causes the liquid to drain into the tank, or (for three-position switches) by turning the handle in the “down” direction. The forks are lowered and the hydraulic lifting trolley is moved out from under the lower plane of the pallet.

To maintain the hydraulic drive of the rotor in constant operation, the rear and front rollers, as well as the plunger rod, should be periodically lubricated using a grease nipple.

The reliability of the use of weeds is ensured by compliance with certain mandatory rules:

1. The device must not be loaded with more than rated force.
2. The load should be evenly distributed between both grips: this eliminates their possible deformation.
3. Dust, dirt, and small objects should not get into the bearing units of the rollers.
4. The dimensions of the space in which the lifter operates must be correctly correlated with the dimensions of the room where the pallets with cargo are located.
5. Pumping the working fluid into the hydraulic cylinder should be done with the full range of movement of the handle.
6. To prevent wear of the wheels, you should prevent the roller from moving on uneven, dirty and rough floors (especially for plastic rollers).

Types of trolleys, rokla (rokla)

Conventionally, we can distinguish six groups of these products according to technical characteristics and tasks performed:

Classic

The length is designed to work with a standard pallet and is 1.5 meters. For these reasons, the width was designed to be 0.54 m. The height of the handle (1.24 m) is suitable for the average height of a storekeeper and makes it easy to carry out all operations. The width of the fork runners does not exceed 16 centimeters, so they freely fit into the gap of the Euro pallet. Approximate weight – 80-90 kilograms.

Extended

There is a group of products whose linear dimensions required the creation of a transporter with deep forks. In this case, the length increased to two meters. This tool is convenient for gripping, for example, a stack of plywood. The width is kept the same to maintain versatility. Of course, the weight increased to 120 kg.

Shortened

The parameters remain the same, only the fork reach is 80 centimeters. This dramatically increases maneuverability, making them suitable for use in tight warehouse spaces. Accordingly, the weight of the product has decreased by 20 kg.

Low profile

There are non-standard clearances under the lifted load, which is necessary to save space in the warehouse. In this case, trolleys with a minimum fork lowering of up to 5.5 centimeters are used. The remaining parameters remain standard. It is worth noting that such equipment is more critical to the quality of the floor surface.

Electrical

Luggage is placed on shelves at a specific storage location. For this purpose, carts with scissor lift are produced, the maximum height of which is up to 80 centimeters. To reduce physical activity, such models are often equipped with an electric drive, which helps to move without the use of force at speeds of up to 6 km per hour.

Specialized

Manufacturers of transporters offer the device with additional options. For example, electronic scales that weigh luggage with an error of up to half a kilogram. Another example is a barrel carrier equipped with a device for gripping and holding standard 200-liter containers.

Recently, companies have begun to equip warehouse equipment with high-tech devices: a barcode scanner and a router. This greatly simplifies indoor logistics.

Characteristics (weight, load capacity, fork length, lifting height)

For different warehouses and different conditions of use, the design of the device should be different. Most of them can be stored and moved by a classic-looking transporter.

The dimensions and weight of the raft, depending on the manufacturer, may differ in terms of load capacity and wheel diameter.

Dimensions

To handle larger luggage, an extended trolley is available. It is distinguished from the first by a fork length of up to 2 meters and an increased weight of up to 3 tons.

Lifting height

The norm is a maximum distance between the floor and the top of the platform of 22 centimeters. This parameter allows you to move standardized pallets smoothly, preventing goods from tipping over. There are models with a minimum lowering of up to 0.055 m. Typically, the clearance under the pallet should be 8 cm. A special type are devices with a scissor lift, which allow you to raise the container by eighty centimeters. This makes it easier to move parts. This type of transporter is often used in production.

Fork length

In tight spaces, if the dimensions allow, it is convenient to use a cart - 0.8 meters. This product has a smaller turning radius and is lightweight. In this case, the maximum liftable load should be no more than 500 kilograms.

Load capacity

This function depends on the power of the jack, on the ability to withstand the loads of the entire mechanical structure (fork rigidity, thickness and strength of rod parts, correctly selected rollers).

Weight

Modern products compare favorably with their predecessors. Due to the use of high-quality steels and the correct fit of all components of the mechanisms, the weight has been significantly reduced. This reduced the workload on employees, and performance was not affected.

Features of hydraulic trolley

Depending on the tasks performed, it is often necessary to equip the tool with consumables - wheels. During merciless operation in production areas with uneven floor surfaces (cracks and potholes in asphalt, concrete), roller bearings and wheel tires often fail. After just a year, they have to be repaired or completely replaced.

The material used to cover the wheel rim is made from:

• • Made of rubber. Carts with such rollers move well and silently over lumpy floors, without slipping on the tiles. They are not afraid of liquid spilled on the surface, such as water, methyl alcohol, denatured alcohol. Withstands negative temperatures. Rubber tires cover rims made of steel or aluminum.
• • Made of nylon. Wheels made of this material hold large loads well. The downside is poor cross-country ability on uneven roads. Hydraulic conveyors with such rollers are supplied to food and pharmaceutical industries, as they are not afraid of aggressive chemical compounds (alkaline and acid solutions, various solvents, oils, salt and ammonia).
• • Made of polyurethane. These wheels are famous for their durability; they last four times longer than the ones listed above. Do not be afraid of the aggressive effects of chemicals.

Replacing worn rollers and wheels is no problem. After this procedure, your baby will last for a long time. You can find the entire range of necessary products on the website of the trading and production company MPlast.

The equipment is equipped with:

• • Brake systems. Operation showed the need to immobilize the wheels. This is important if the surface of the warehouse has a slope. Many modern models are equipped with a rolling stop device. The control handle can be located either on the handle or below, next to the rotary wheels.
• • Product weight meters. A very useful option that allows you to significantly reduce the time a storekeeper spends on accounting.
• • Retractable forks. In some cases, it is necessary to lift weights not from the floor, but from a certain height. A simple device greatly facilitates the work of loaders and installers.
• • Lifts. Engineers have developed lifters capable of not only moving, but also lifting containers with products to a height of up to 80 centimeters.

What to look for when choosing a trolley

Which roach to choose is a question often asked not only by beginners, but also by experienced businessmen. After all, such units are today produced by different manufacturing plants from Europe and China.

Manual hydraulic shovels are valued for their simple design, ergonomics, maneuverability, and the ability to transport even large loads on pallets indoors or outdoors. In this case, there is no need to buy fuel or connect electricity, since the raft is equipped with a hydraulic mechanism powered by human physical strength.

When choosing a baby, you need to pay attention to its type:

• Standard. In this case, the lifter consists of a fork block and a lifting mechanism with a hydraulic pump, handle and piston. Such devices lift the load to a distance of 20 cm from the floor, and lower it to 85 mm from the floor (some models - up to 35 mm).
• With built-in scales. They allow you to control the shipped goods. Some models are equipped with functions of summing, counting the number of packages, and printing receipts.
• For use in aggressive environments. Most often, such models are needed in production where there is a humid, alkaline or acidic environment. The elements of the device are resistant to such influences and do not rust.
• For cylindrical loads. Such devices allow you to transport coils, rolls (paper, cardboard, foil or woven materials).
• For working on uneven surfaces. These trucks are designed for off-road use: they can be used on the street because they have wide and powerful wheels.
• With scissor lift. The X-shaped lever mechanism allows you to lift the load to a height of up to 80 cm from the floor.

Premium class

Such bastards are considered the best. But at the same time they are much more expensive than their analogues. The trolleys are manufactured in Europe and the European Union. This segment includes products from the brands Rocla, BT, etc.

Middle class

The units are manufactured in Asian countries. Their quality is almost as good as premium products, but they are not as expensive. These are products from brands such as Tisel, Otto kurtvach, Lema, etc.

Budget (economy) class

Most often, such carts are made in China. They are inexpensive because they do not use the highest quality components and materials. However, cheap devices also cope with their functions. This price segment includes products from the brands Tor, Smart, Eurolifter, Niuli, etc.

In addition, in the MD-Progress online store you can buy used rams of excellent quality that are in working condition. As a rule, these are units that the previous owner practically did not use, or models that were repaired before resale, and parts that had worn out during operation were completely replaced.

When buying a used trolley, you need to pay attention to whether the hydraulic unit and the roller block on the forks work well. It is these elements that allow you to move the load smoothly and reliably.

How to choose a hydraulic pallet truck

To make a decision on choosing a product, you need to decide on the tasks that need to be performed. You need to understand under what conditions and how intensively it will be used, what maximum weight needs to be moved. Should you spend money on improved models with additional options, such as electronic scales and a barcode scanner?

Rules of care and operation

According to the technical data sheet, the service life of warehouse equipment is from three to five years. But if you care for it properly, it will work much longer.

Our recommendations:

• • Do not overload the cart. The weight of the product must correspond to the stated data in the document.
• • Distribute the mass evenly on the forks (do not lift goods at the tips of the platform).
• • Inspect the undercarriage daily. Remove objects that fall on the wheels (wire, threads, leaves, tree branches).
• • To maintain the working condition during movement, it is necessary to lift the forks by pressing the lever, which is required according to the technical specifications.
• • There is a rule: you should pull the rokla along with you. Pushing yourself in front of you is prohibited.
• • Inflation should occur as written in the instructions, from the starting point to the stop. Otherwise the node will fail.
• • Before purchasing equipment, pay attention to the condition of your floor. If the surface is deformed, the wheels of the standard model will quickly break.
• • Watch the oil level in the hydraulic unit. Avoid leakage. Change the lubricant in a timely manner.
• • If air has entered the hydraulic system, it must be removed by pressing the handle without loaded trays.

Price

First of all, the price of the equipment depends on the load-carrying capacity of the product and the length of the platform. Often the cost is inflated by the manufacturers themselves and the product does not justify the functional characteristics of the product. Therefore, it is worth paying attention to the price-quality ratio.

In our article, we clearly showed in photographs what a trolley or hydraulic trolley means, and told how much it weighs and how to care for it. To better understand how the equipment works, watch the video:
