Rokhlya with a lifting mechanism DIY repair

Do-it-yourself rohly repair is a quick and inexpensive way to bring useful warehouse equipment into working order. Many breakdowns can be repaired without the help of specialists, but you should not be overconfident. Sometimes it is better to take the device to a service.

The hydraulic shovel is a handy transporter. It moves loads mainly on pallets. A special feature is the presence of a hydraulic jack that raises and lowers the forks. Such carts are used in warehouses, in large stores. They greatly facilitate the work of storekeepers and auxiliary staff of retail outlets. That is why do-it-yourself repair of hydraulic carts is an interesting and useful topic.

Rohly's design is simple. Metal forks mounted on wheels securely hold the load. They are raised and lowered using a hydraulic handle. The height of the forks can be adjusted. The lifting capacity of some models reaches 2.5–5 tons.

Rice. 1. Do-it-yourself rohly repair

Dismantling rokhly is a simple undertaking if you study the design features of the equipment. For example, there are trolleys with built-in brakes, rolling casters, single or twin wheels. How to disassemble a rokhlya without damaging it? First, familiarize yourself with the main types of malfunctions and their causes.

1. Malfunctions and repairs of the waterworks

The hydraulic unit is the most important element of the trolley. Repairing it may involve replacing valves or seals, grease, or the entire body. It is better to entrust the solution to the problem to specialists. It is easy to find hydraulic faults: a squeak is heard, loads are being lifted or lowered heavily.

2. Repair or replacement of the valve

Unstable lifting, slow lowering of the cylinder, the appearance of a leak in the pumping part of the hydraulics is a reason to make sure that the valve is working properly.

Damage to the hydraulic lever handle is the most common. They appear due to the careless handling of technology. Sometimes, for repairs, it is enough to change the stepper lever or spring, in some cases, the entire handle. Also, experts can resort to welding.

Frequent use of the fork will abrade, deform and break the forks. To repair them, reinforcement, adjustment of the length of the rods, welding and straightening are used.

5. Malfunctions of the chassis

The undercarriage consists of several elements, each of which can fail. These can be wheels and bearings. Fasteners often break down: axles, carriages, brackets and other components, which are easy to replace on your own, without contacting the masters.

Rollers and steering wheels allow the cart to move, transporting the load in the desired direction. Exceeding the permissible load or careless operation will lead to breakage of these elements. Repair involves replacing old parts with new ones. You need to choose wheels instead of faulty ones, based on the characteristics of the trolley, cargo and the specifics of the floors in the warehouse. For example, you can supply wheels made of polyamide, metal-polyurethane or metal-rubber.

7. Oil change, or Do-it-yourself rohly repair, if the load does not rise

Do-it-yourself repair of the rocket (the load does not rise) can be done quite easily if the reason lies in the lack of oil. For this, hydraulic or simple spindle oil is introduced into the hydraulic unit through the filler bolt. It is impossible to fill in a simple motor, it does not have the required viscosity. Grease may have leaked out through the seal. In this case, it should be replaced.

It seems that the health of the internal contents of the rohly is more important than its appearance. This is not entirely true.Painting individual elements or the entire trolley is not only about aesthetics, but also protection. The paint protects the equipment from corrosion and excess dirt. On clean surfaces, hydraulic leaks are detected more quickly.

As already mentioned, wheels and casters often fail. You can replace them yourself.

The roller axles fix the pins, they should be knocked out. This is done using a punch with a diameter of 4–5 mm and a hammer. When the pins on both sides are removed, knock out the axes of the fork rollers. To do this, use the same hammer and drift, but with a larger diameter. If there is corrosion on the axles, concentrated acetic acid will help facilitate the removal process (a few drops above the bearing - and after 15 minutes the roller can be released).

Since the hoisting trolley is an important helper in warehouses of different types, questions of how to repair the loader arise quite often. Here are some tips:

1. if the load does not rise, check the oil level;
2. if a leak is found from under the spring under the handle, replace the plunger cuff;
3. if a leak appears near the valve lever - the seals are worn out, put new ones;
4. if the oil is at the correct level and the cart does not lift the load, check the valves;
5. if the cart is hard to move with the load, lubricate or replace the roller bearings.

People who are well versed in mechanisms and who have been using equipment of this type for a long time will be able to independently adjust the rocket. If the experience is not enough or the cause of the breakdown cannot be determined, it is better to entrust the repair to specialists.

Everyone knows that the proper operation of warehouse equipment used for loading and unloading operations in warehouses is an integral part of an uninterrupted cycle of movement of goods within the warehouse, and downtime is fraught with damage to both warehouse owners and tenants.

To ensure the smooth and reliable operation of hydraulic hand carts, it is necessary to carry out their maintenance and repair. It is better to entrust this to professionals, which include our company Sklad.ru. We repair not only hand pallet trucks, but also loaders, reach trucks, stackers. But if your specialists responsible for the operation of warehouse equipment have the appropriate experience, skills, the necessary tools and spare parts, they can make repairs on their own. You can and should try to make a hydraulic carriage yourself, but before proceeding with the repair, it is necessary to take into account the qualifications of the performers, its labor input and cost.

Before proceeding with the repair of a hydraulic carriage, it is worth knowing that regardless of the brand and manufacturer, all hydraulic carts have the same design and principle of operation, and since almost all carts operated in Russia are made by numerous Chinese manufacturers, using the same components in the production. of the same manufacturers, then their units are in most cases interchangeable, therefore, the spare parts of your hydraulic trolley necessary for repair can be replaced with spare parts of trolleys of another brand. We draw your attention to the fact that low-price trolleys, in the production of which low-quality components are used, fail much faster than medium and high-price trolleys, be prepared for high operating costs due to more frequent repairs.

This type of damage occurs most often, since they can appear not only during the movement of goods, but also through extraneous influences, for example, a fall of a load from a height, or a collision of a vehicle or a forklift, as a result of recent influences it is quite difficult to repair a hydraulic cart, but it is possible ...

When the forks are deformed, you cannot do without an autogen, a welding machine and a sledgehammer, since the forks will have to be leveled, given their original geometry, and the gaps in the metal will have to be welded.

If the handle is damaged or torn off, and this can happen in the case of pushing a pallet with a load on the handle, dropping the trolley from the car body or dropping a load on it, it must be leveled, welded, and if it is impossible to replace it with a new one, and installed in place with bolts or pin.

The deformation of the rods is a consequence of overloading, it is eliminated by giving them their original geometry using autogenous heating and leveling with a sledgehammer, and, if necessary, they can be further strengthened by welding a metal plate.

In most cases, breakage of rollers and wheels occurs during the operation of the pallet truck on uneven surfaces. The repair of these units is the least laborious and costly due to the low cost of spare parts and a short repair time.

During operation, nylon rollers and support wheels are chipped, and polyurethane and rubber ones are worn out, in addition, erasure also occurs along the axis, which can also deform. In this case, the repair involves replacing the rollers and supporting wheels with new ones, and depending on the state of the axle, it can be leveled by holding the axle in a vice and using special equipment or a simple thick-walled metal pipe, or replaced with a new one.

This type of breakdown is extremely rare and occurs when the cart is overloaded. It is difficult and labor-intensive to carry out repairs, since the disassembly of the hydraulic unit is necessary to carry out the repair, and this requires not only experience and knowledge of hydraulics, but also the availability of the necessary tools. When deciding on the repair of a hydraulic unit, it is necessary to take into account that the cost of repairing it at a price can be comparable to the purchase of a new hydraulic carriage. But the decision is up to you, and we will only give some recommendations.

At first glance, the device of the hydraulic unit seems rather complicated, but in the event of a breakdown, it is quite possible to repair it yourself. According to the principle of operation, the hydraulic unit of the bogie is the same manual hydraulic single-plunger jack. With intensive use, the main reason for the failure of the unit is either overload or failure of hydraulics.

When overloaded, the stem can deform (receive a bend) and wedge in the assembly. In this case, there is only one way out, replacing the stem, due to the fact that it is made of special steel, it is not possible to align it.

• Leakage of working fluid (hydraulic oil) during storage and transportation of the hydraulic trolley, the hydraulic unit must always be in a vertical position, otherwise oil will leak out and air replaces its place, which leads to a slowdown and termination of the unit operation.
• Internal corrosion leads to a deceleration of the stem and leads to increased wear on the lip and seals.
• In the bleed valve, the seals can be worn or the valve clogged, obstructing the flow of oil in the assembly and also causing oil to bypass.
• Intensive operation, the ingress of abrasive particles on the stem, or mechanical damage to the stem, wear of the seals and O-rings, which leads to leakage of hydraulic oil along the stem.

Hydraulic oil is the part of the hydraulic unit that drives the hydraulic mechanism and requires replacement for reliable operation. During the operation of the hydraulic cart, it is necessary to change the hydraulic oil periodically, every 6 months. To do this, you need new hydraulic oil and flushing fluid.

• The plug is unscrewed and the used hydraulic oil is drained;
• The mechanism is flushed with flushing liquid, sometimes for better cleaning it is necessary to repeat flushing;
• Fill the hydraulic unit with oil to the maximum mark, close the plug, and bleed the system (during the pumping process, it is necessary to add oil to the system). You need to pump it several times, raising and lowering the stem until it stops moving out without jerking, then add oil to the maximum level. The cart is ready for use.

In this article, we will consider the topic: hydraulic repair cart. Namely, it will be repaired under fork lift unit with roller replacement... The reasons for the repair are usually different, we will analyze one of the standard breakdowns of hydraulic trolleys, the bearing under the fork roller collapsed, in total, the trolley scrapes and grinds down, the result is wear, below are step-by-step photos DIY repair rohly... And so let's get started, first we remove the old rollers, the technology is simple: we knock out the stopper, then the finger (shaft) of the rollers from the fork bracket, then if the hinge shaft is not very sharpened, we turn it 180 degrees in the same way.

The mechanisms are ready for repair, we put the repaired unit in a convenient position, prepare patches, weld with arc welding at a reduced load with a 2 mm electrode, or with a semiautomatic device.

Further, using the cleaning technology, we remove all unnecessary growths and irregularities, followed by priming and installation under the fork rollers, we collect everything in the reverse order. The repair of the cart is finished. Good luck with everything. be healthy.

Thank you. interested in electric rokhl - there is not enough pressure in the hydraulic system. where is the pressure valve?

dd what model? there is not enough pressure in the hydraulic system - how does it manifest?

Powerhouse Pikabulishnaya. Help.

Maybe someone has come across such a problem that rokla does not want to lift even heavy boxes? Or maybe someone just knows where to pour oil in this thing?

Well, a syringe or a pear to help

Does the empty cart lift? If so, it is worth replacing the o-rings in the hydraulic system. Perhaps there is little, but it is poisonous. Google repair kit for this cart and change 🙂

she raises, but literally a couple of cm.

Kick-ass, dial on the ad.

no, they took me by acquaintance

litter. in your tags the repair was registered, this league was not issued.

As usual, I saw the repair tag with one eye and added it. I apologize again

No warehouse facility is complete without pallet trucks and stackers. Modern models are reliable and productive equipment, equipped with many additional features and functions, including the presence of electrical circuits in electric and self-propelled trolleys. Such mechanisms provide obvious advantages, provide convenience, comfort and speed of movement of products within and behind warehouses.

Manufacturing companies regularly modify and update product lines due to the high demand for them and the interest in multifunctionality. Mechanisms become more complex and reliable, but over time, even the highest quality equipment malfunctions.

The reasons for the failure of hydraulics on carts and other annoying breakdowns can be very different, but, as a rule, these are:

• natural wear and tear, development of the resource of mechanisms and systems;
• violation of operating rules;
• excess loads, too intensive operation, which is especially typical for large warehouses;
• transportation of goods on a hydraulic cart, the mass of which exceeds the permissible carrying capacity of the warehouse equipment (indicated in the passport), which leads to the failure of the hydroelectric complex;
• gripping the load to a partial length of the forks;
• ingress of foreign objects between the rollers of the running gear and the carriage, which leads to jamming and failure of structural elements;
• premature erasure of the forks, their deformation and floor due to incorrect movement to the pallets;
• mechanical damage;
• constant excess of the pumping cycles of the hydroelectric complex;
• erasure of rollers due to unevenness of floor coverings;
• lack of lubrication of rubbing mechanisms.

If all the rules of use and safety precautions are observed during the operation of the hydraulic carts, the equipment will serve for many years, in accordance with the service life declared by the manufacturer.

The most common defects requiring immediate repair in order to prevent a complete exit from standing equipment include:

• failure of hydraulics, its incorrect operation, requiring adjustment;
• failure of an electrical circuit, battery, charger;
• failure of the trigger in the control lever, rolling and rolling rollers, their carriages;
• chassis defects, etc.

This is just a minimal list of breakdowns and defects faced by warehouse workers. In order to ensure that improper handling of special equipment does not lead to downtime and financial losses, it is recommended to carefully study the rules for working with hydraulic carts before starting operation.

This is especially true for the latest generation models, oversaturated with additional systems.On them, often, even the oil, the set of O-rings can only be changed in specialized workshops.

If there is a need to repair the hydrosystem or other structural elements, it is recommended to contact a reliable service center. The intervention of amateurs can result in a complete failure of the mechanism or failure of systems.

We watch in the video about how the hydraulic cart - rohlya - lema works:

The emergence of a new warehouse equipment, called rokhlya, was caused by an increase in the turnover and loading of warehouses. What was needed was a simple and maneuverable trolley with a lifting mechanism capable of working in a confined space, and for the first time such a device for lifting and movement of goods on the Russian market was presented by the Finnish company Rocla. This name, which sounds like a booze in Russian, has extended to similar devices and other manufacturers that can be bought on the warehouse machinery market.

Rokhlya is a simple and reliable storage mechanism based on the principle of a jack: the pressure of the hydraulic fluid from the discharge plunger is transmitted through the hydraulic fluid to the rod of the working cylinder, which raises the forks with a load to a height.

The pressure in the working area of ​​the plunger is created by the muscular force of the operator by tilting the trolley handle downward. 5-7 strokes are enough to raise the load to the maximum height.

Rokhlya is easily and safely controlled by one person when moving with a load on the weight, it is also easy to lower the load and place it in stacks.

The control of the rocket does not require special training, and the design of the device is so reliable that it does not require periodic maintenance and works without failures for a long time, and the number of models on the market that you can buy is impressive.

According to their design features, rohly can be divided into the following types:

• standard;
• small-sized;
• long;
• low profile;
• with scissor lift;
• with hydraulic scales;
• with increased maneuverability;
• electrical.

Standard pallet trucks are reliable handling equipmentdesigned to facilitate logistics work in warehouses and large shopping centers.

Rokhli of this design have the following features:

• the length of the pitchfork is 1150 mm;
• carrying capacity - from 2500 to 5000 kg;
• lifting height - up to 200 mm.

The single or tandem steering wheel is made of nylon or rubber, which allows the trolley to move in any direction and on any floor.

Rokhli have a convenient control handle, which simultaneously performs the function of raising and lowering the load.

Compactness, mobility, high carrying capacity and low price make them indispensable for mechanizing the processes of moving loading and unloading inside warehouses.

Due to the high reliability, the mechanisms will not lose their reliability and functionality despite a significant price reduction.

Hydraulic small carts - This is a type of lifting device with the following main characteristics:

• pitchfork length - 800 - 1000 mm;
• carrying capacity - 2500 kg;
• lifting height - 1224 mm;

The small dimensions of the carts make them convenient for working in small-sized warehouses, and the low price allows you to save on the maintenance of the staff of loaders. Narrow corridors and aisles between shelves are not an obstacle for them when transporting goods from the warehouse to the store shelves.
