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

October 9, 2022 Equipment and malfunctions admin

In many cases, self-propelled pallet trucks with a lifting mechanism are required because without them many activities would be much more labor-intensive.

Such carts are called electric trolleys and are used in many areas, but if there is a need to purchase them, you should first familiarize yourself with the features of the technology and the nuances of controlling the cart. Electric weeding is offered at a competitive price in Rostov.

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.

Disadvantages of being weak

Ease of use and versatility in rigging work are undoubted advantages. The disadvantages include:

a) — The need for special standardized pallets;

b) - For normal operation, Rokhla needs a smooth, durable and strictly horizontal floor. Even a small ledge, slope and rolling a cart with a heavy load will become difficult, or even impossible.

However, modern technologies make it possible to solve the problem of evenness of floors at low cost, while the unification of pallets is solved at the level of standardization, and a small hero with the funny name “rokhlya” has long become a common attribute of even small warehouses.

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.

Features of the device and scope of application of hydraulic trolleys

This device is a U-shaped trolley, in which the body function is performed by two-pronged forks with wheels. And at the connection of these “teeth” there is a hydraulic lifting mechanism and a handle. The handle plays the role of a lever when lifting and a steering wheel when transporting. The fork design of the device determines its main function - the transportation of goods lying on pallets. Thanks to their safe and simple design, these units can be used by people without special skills and knowledge. In the USSR, such carts appeared in the 60s of the 20th century. The main supplier was the Finnish company Rocla, which gave the unit a convenient name - rokhlya.

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.

Tips for the correct use of weeds

• — Never place products weighing more than the maximum lifting capacity on carts. Otherwise, the hydraulic system will quickly become unusable.
• — To prevent fork deformation, distribute the load evenly between both pallet handlers.
• — Check the roller bearings regularly. Make sure that dust and foreign objects do not get there. This applies equally to street dirt.
• — Pump fluid into the working cylinder with the full range of motion of the raking control handle.
• — To avoid premature wear of the wheels, try not to use the rollers on uneven, heavily soiled or rough floor surfaces.

Important advice. Always buy quality trolleys from leading manufacturers. Inappropriate saving in the present leads to losses in the future. Very cheap trailers break quickly and reduce the safety of cargo transportation. Ultimately, major equipment repairs and product damage due to unexpected falls significantly increase warehouse maintenance costs.

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.

Types of trolleys, rokla (rokla)

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

Classic

General characteristics of standard products
Length(cm)	From 110 to 280
Height(cm)	from 108 to 125
Width(cm)	from 53 to 58

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.

Name	Rotator for barrels	Barrel tipper	Tipper with lift
Model	DT250	HD80A	DA40B
Description	Specialized up to 210 liters;	With tipping function – 210 l.	Lift function to a height of 1.35 meters.
Gr. lifting capacity in kilograms	250	364	400
Size(cm)	57,2	57,2	57,2
Trolley weight (kg)	42	50	190

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

The principle of operation of the rokhli

First, for comparison, how cargo is transported on a regular cart or wheelbarrow:

The load is lifted, carried, and placed on a wheelbarrow. Next, they take it to the right place, lift it, remove it from the wheelbarrow, and lay it down.

The basis of the work of the lifter is that in order to move the load, it does not need to be lifted high, it is enough to be lifted off the floor literally a couple of centimeters.

This happens as follows: Each cargo unit is placed on a special pallet, which provides a gap of several centimeters between the cargo and the floor.

The roach is rolled into this space, and then the hydraulic booster comes into action. It consists of a small and a large cylinder filled with hydraulic fluid and having pistons.

The swing of the lever located in the front of the rotor moves the piston in the small cylinder. The piston compresses the hydraulic fluid, and a special valve prevents the pressure from dropping when the piston moves back. And the hydraulic fluid transmits pressure to the piston in a large cylinder.

In accordance with Pascal's law, a large piston creates a force that exceeds the force on a small piston by the same amount of times as its area is larger.

By applying a load of a couple of kilograms to the lever, we get a force of several tons.

This force lifts the body of the vehicle relative to the wheels. Resting its steel “back” against the pallet with the load, the little one lifts it too.

Now it can be rolled along with the load to a new place. After the load has been transported, the pressure in the liquid is gradually reduced by a special regulator, and the load is carefully lowered to the floor.

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.

Load capacity	T	2,5
Platform length	m	1,15
Width	m	0,55
Platform height	m	0,2
Number of wheels	PC	2/2
Rear wheel diameter	cm	20
Roller diameter	cm	8

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.

Manual hydraulic trolley Rokhlya

The turnover in warehouses has increased to such an extent that an ordinary hand cart, suitable only for transporting goods, no longer satisfies demands. It was replaced by the Rokhlya hydraulic trolley with increased load capacity and capable of moving loads of significantly greater weight. Cargo trolleys that simultaneously have a weight element are becoming increasingly relevant. Easy to operate, in small warehouses, it replaces an expensive forklift, easily handling cargo weighing up to several tons.

Advantages

The Rokhlya manual hydraulic trolley, free of disadvantages, has a number of undeniable advantages that facilitate the process of moving goods with its help.

• Multifunctional handle with which the trolley is controlled - moving forward and backward, turning left and right and lowering and raising;
• The versatility of the design allows it to be used in warehouses, shops and other premises where there is a need to transport a variety of goods: barrels, pallets, rolled materials;
• The reliability of the Rokhlya cargo trolley is determined by a minimum of parts, including only a reinforced chassis, handle and hydraulic pump;
• Increased load capacity (up to 3.5 tons) exceeds the parameters of any simple hand truck;
• The ability to replace support and moving wheels depending on the floor covering used in the room, which significantly reduces noise characteristics and reduces wear.

Varieties and sizes

General dimensions of the Rokhlya hydraulic trolley, related to all of the above modifications: total lifting height of the fork platform 195 mm; height above the surface with hydraulics lowered 85 mm; standard lifting platform width is 550 mm. The front (steering) wheel has a size of 180x50 mm. The temperature range at which normal operation is possible is from -20°C to +40°C. The hydraulic cylinder uses L-VH 46 hydraulic oil.

Based on the needs of the customer, it is produced in several versions, differing in load capacity, the size of the lifting fork-shaped platform and the rear loading wheels of the roller type.

• The Rokhlya hydraulic trolley with scales is equipped with a lifting platform of 1150 mm. The total length of the trolley is 1580 mm. The size of the two rear roller wheels is 80x70 mm. Total weight 120 kg;
• Hydraulic trolley with an extended platform length up to 1800 mm. Weighs around 150 kg;
• The trolley with electronic scales is equipped with a 1150 mm lifting platform. The total length of the trolley is 1580 mm. The size of the two rear roller wheels is 80x70 mm. Total weight 120 kg;
• Trolley with a standard fork-shaped platform, 1150 mm long and 550 mm wide. The polyurethane rollers used for Rokhli have a size of 80x70 mm. Weight, varying depending on the load capacity of the trolley, 76-80 kg;
• A hydraulic trolley with a shortened platform length of 800 mm with rear loading rollers measuring 80 by 70 mm and weighing 73 kg;
• The pallet conveyor is equipped with a lifting platform with a standard length of 1150 mm, but slightly narrower in width - 530 mm and rear rollers 80x60 mm. Weight 70-85 kg.

Peculiarities

Rokhli hydraulic trolleys are produced with a lifting mechanism designed to lift weights up to 3.5 tons. The body contains special high-strength steel with low carbon content. It is manufactured by cold pressure on a stamping press followed by welding of elements on a robotic line.

The front drive wheel and rear steel rollers are coated with shockproof polyurethane. The handle that controls the hydraulic platform is coated with a polymer material that is resistant to low temperatures.

Operating modes

The Rokhlya hydraulic trolley is controlled using a handle with a control lever located on it, which is designed to control the operating modes of the trolley. The lever has three positions:

1. Upper – “Lift” mode designed for lifting the fork platform. Maximum up to 195 mm;
2. Lower – “Descent” mode, which lowers the fork platform. The distance to the floor with the platform lowered is 85 mm;
3. Medium – “Motion” mode.

Weight platform

The Rokhlya hydraulic lift with scales requires the fulfillment of certain operating conditions and the acquisition of certain skills for productive work with a high-precision liquid crystal display. It is worth considering that its performance is guaranteed at temperatures from -5 to +40°C.

Power is supplied from a 6-volt battery. The battery is charged through an adapter that provides a constant voltage of 6 volts with a current of 4 amperes. The charging time should not exceed 6 hours. Load capacity is 2 tons or more.

Compliance with operating conditions when working with scales comes down to the following points:

1. Do not use the scale in the rain or wash it with running water. If water gets in, immediately remove it from the surface of the scale;
2. Do not allow direct sun exposure to the surface or overheating from another heat source;
3. It is necessary to ensure that the weight of the cargo to be weighed does not exceed 3 tons;
4. When putting the scales into operation after storage or long periods of inactivity, you must make sure that the battery is fully charged. If the battery is discharged, the weight readings will be incorrect.

Safety precautions

Working with heavy loads is always associated with a certain danger to the life and health of people. The Rokla hydraulic trolley is also a source of increased danger and when operating it, safety precautions must be observed.

• During a break in work or at the end of it, it is necessary to ensure that the lifting mechanism and protruding traumatic parts of the forks are lowered as far as possible, and the mode switching lever located on the handle is in the middle position;
• Movement on an inclined surface is permitted only on a concrete ramp specially equipped for Rokhli. It is prohibited to turn or move diagonally on the ramp;
• The weight of the transported cargo must not exceed the permissible load capacity of the trolley. Broken or defective pallets must not be used to transport cargo;
• When moving, you must constantly monitor the distance between the cart and other objects so as not to damage the warehouse equipment or harm people;
• An operator who has been instructed and passed the exam for the right to operate a hydraulic trolley is allowed to work.

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:

What is an electric weed

Such equipment was once developed on the basis of the most ordinary hydraulic trolley. Of course, it is more convenient, therefore it is better controlled due to the use of electrics.

The product is intended for the rapid transportation of various cargoes, and the latter must be loaded on pallets, called pallets. Pallet dimensions must be standard.

Electrical equipment is placed in a special block, immediately behind which there is a control handle. On the other side there are long runners designed for work. The carrying capacity of an average trolley, suitable for effective work in various fields, is from one and a half to two tons.
