DIY electric stacker 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 that 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 spoiler 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.

• oil leak from the pump wear of the cuff, damage to the pump piston
• when pumping up the pump, unstable raising or slow lowering of the working cylinder - repair of valves or wear of the cuff, damage to the working cylinder
