Of course, the operation of any device leads to the fact that it gradually fails. Some parts break, grease dries out, etc. All this also applies to pallet trucks, the repair of which is quite simple, but you need to know how and when to do it.

General information

Hydraulic trolley, rokla, rokhlya, fork trolley - these are all names of the same storage device. Despite the fact that this device is very simple, it still breaks down, especially if it is used improperly. As practice shows, subject to careful handling, the service life of the deadwood is about 5-8 years. After this period, it is imperative to start repairing the hydraulic trolley. Of course, the warranty from the manufacturer will be much less than 5-8 years. Most often, this period is 1-2 years, depending on the confidence of the manufacturer in his product. However, even this period of time, the device may not last if handled carelessly.

Rules for working with a cart

In order to delay as far as possible the moment when it is necessary to carry out repairs on the hydraulic trolley, it is necessary to know the rules for its operation.

1. First and obvious enough is the careful handling of equipment.
2. An important detail that many underestimate is the instruction. It is necessary to familiarize yourself with it immediately after buying a rokhli. Outwardly, they are all almost the same, but there is a difference in the details, failure to comply with which can lead not only to damage to the equipment, but also to injury.
3. Despite the fact that the cart is designed to carry goods, it must be loaded wisely. You can’t overload such a device at all, but you need to download it as follows. For example, if according to the passport data the unit is designed for a maximum weight of 1.5 tons, then it is better not to load more than 1-1.2 tons.
4. A very important point will be the distribution of cargo over the area of the forks. In order to delay the repair of the pallet truck as much as possible, it is important to ensure that the maximum pressure from the load is approximately in the middle of the device. If the fork ends are overloaded too much, effects such as bends, cracks, etc. can quickly occur.

Trolley Service

Maintenance of this equipment is quite simple as the construction itself is not too complicated. But it is worth noting that this is a very important part in terms of caring for the cart.

• Checkperformance. This is possible and should be checked every day before starting work, as well as after completion. It is necessary to inspect the device for the performance of all its mechanical components, for the absence of cracks and other defects, for the absence of debris in the wheel part, etc.
• Blurring. In order to avoid frequent repairs of the hydraulic trolley, the deadbolt must be lubricated. This operation must be carried out once a month. Most often, the nodes that need to be processed are bearings, pistons. If there are any additional nodes, they will be indicated in the technical documentation.

Design and malfunctions

It is important to understand that the design of this equipment is very simple, and therefore the chance of breakage is small if used carefully. The main components are: a base frame, support wheels and rollers, a pair of forks, a hydraulic unit and its lever-handle. Because of its simplicity, it is considered quite reliable.

Here I would like to note that the number of companies that provide repair services for hydraulic carts in Moscow, for example, is quite large. And this suggests that many neglect the rules for handling equipment.

Almost all malfunctions of such equipment are associated with one node - forklifts. By the scale of the malfunction, the problem is most often divided into three groups. Repair and its costwill depend on which particular group the breakdown of a certain piece of junk will belong to.

First category

The first group includes the simplest repair of hydraulic carts, the device of which was not too badly damaged. It is called cosmetic. Most often, this type of work is understood as the simplest maintenance service, which includes the correction of the smallest flaws in the work, as well as the replacement of those parts that have become unusable due to natural wear and tear during operation. These small parts include, for example, rollers and steering wheels with integrated bearings.

In itself, the process of replacing them is considered the simplest. The only thing you need to know for sure is exactly what material they must be made of in order to be suitable for the normal operation of the cart. Do-it-yourself repair of a hydraulic trolley is quite realistic, if the breakdown belongs to this category, you just need to know which wheels to put on.

Change wheels

When changing wheels, consider the flooring in the storage area. If it is even and clean, then the installation of nylon wheels and rollers is allowed. The advantage of these elements will be a quiet and smooth running. Otherwise, if the floor is rather rough and uneven, then it is best to purchase wheels made of polyurethane or rubberized metal. A big plus of these parts will be a high rate of endurance. However, even when installing such wheelsets or rollers, it is best to followensure that the warehouse is maintained at least as clean as possible and that the most damaged areas of the floor are repaired. This one-time operation can be much cheaper than constantly changing the wheelset.

Besides this operation, the first category includes such operations as cleaning, lubricating, touching up scratches, changing the oil in the hydraulic unit. Repair of a deadlift (hydraulic trolley) at this stage is quite cheap, but very important, since its timely implementation can greatly extend the life of the equipment and delay the occurrence of more serious breakdowns.

Second group

The second group includes a complete repair of the cart. The provision of services to correct defects from this category is the most in demand. Malfunctions related to this group are breakdowns of the hydraulic handle-lever. This element most often fails due to careless handling. Most often, as a repair, it is necessary to replace the entire handle, its spring or stepper arm. The second most common failure is the failure of the hydraulic system itself. As a repair, in this case, it is necessary to change the seals and valves, or the entire body assembly. It is important to note here that do-it-yourself repairs of this complexity are no longer considered reasonable. For this reason, if the equipment squeaks, is difficult to raise or lower, or shows any other signs of breakdown, you should immediately contact the service center.

To avoidbreakdowns in the hydraulic system, it is necessary that the operator fully lowers and fully raises the cart. In this position, the load pressure on the system will be minimal.

Faults and repairs of hydraulic carts of the third group

This category already belongs to the overhaul. Naturally, it is considered the most complex and expensive. In this case, it would be advisable to first calculate the repair costs, then take into account the date of assembly and think that if the equipment is old, and the repair cost is more than 50-60% of the initial price, then it is better to just buy new equipment.

If repair is needed, then it can be of two types. The first type is a complex work, the essence of which is to replace almost all the nodes of the cart. The second type is directed repair. In this case, the greatest attention is paid to the elimination of mechanical faults. Such breakdowns include severe cracks, kinks, bent parts, etc. It is also important to consider here that after a major mechanical or complex repair, not a single service center will guarantee that the cart will be as durable as after it left the factory. You will have to observe many restrictions during the operation of the device.
