The manual pallet truck is undoubtedly a common handbarrow in modern logistics, which is found in factories of all sizes. It is also widely used in various industries such as postal services, airports, warehouses, workshops and supermarkets. In a modern society, the handling of materials is inseparable from manual pallet trucks. Thus the truck is also called “the king of land”.
In the process of social development and changes, the demand for manual pallet trucks is also undergoing new changes, and the number of companies with personalized needs is gradually increasing. Various types of trucks appear in the market, in order to meet market demand, such as: widened manual trucks, large-tonnage manual trucks, scissor manual trucks, electronic scale trucks, electric trucks, etc.
However, all types of manual pallet trucks are faced with a problem. That is, the after-sales service and maintenance of manual pallet trucks. As the saying goes: there is nothing in the world that is not bad. No matter how good the product is, there are times when it is damaged or eliminated. Therefore, solving the after-sales service maintenance problem is the guarantee for the continuous operation of the manual pallet truck.
Today, Yide Casting will give you an analysis of the 5 key parts that are prone to having problems. And above all, how to solve these problems.
1. Oil pump
The oil pump is a key part of all trucks. Once there is a problem with the oil pump, it means that the truck is declared to stop working. Even though the other parts are good and without any damage. The oil pump consists of a lot of parts. Among them, dust-proof rings, O-rings, steel balls and other parts are prone to having problems. Once problems with these parts are found, the quicker solution is to replace these accessories.
2. Oil cylinder
The oil cylinder plays a vital role in the entire lifting process of the truck. And it is also used to rise and fall the goods. Therefore, if the fork cannot be lowered or raised, the reasons are: 1. The piston rod and the oil cylinder may be damaged due to overload or partial load during the load; 2. The piston rod is exposed for a long time and rusts, thus hinder the smooth movement of the piston; 3. The adjusted nut and hex nut are not in the correct position. At this time, we should replace the piston rod or cylinder, lower the truck to the lowest level when the truck is not used, and readjust the nut.
3. Oil seal
The oil seal is the key component between the piston rod of the oil cylinder and the cylinder barrel. Imported sealing rings are generally used. Mainly because of good sealing performance, wear resistance and long service time. And 70% of the oil leakage of the oil cylinder occurs on the oil seal. If oil leakage is found in the oil cylinder, check it in time. If the sealing ring is aging or damaged, replace it with a high-quality one.
Handling wheels will wear out if they are used for a long time. There are also many kinds of wheels for handling vehicles, such as nylon wheels, PU wheels, polyurethane coated nylon, rubber wheels, bakelite, etc. Most trucks are equipped with nylon wheels because they are common in the market and cheap, but they are less worn and noisy when walking. Please replace the transport wheels in time if they are worn to a certain extent.
5. Lever frame
The lever frame is the key component connecting the oil pump and the push rod. The lifting support of the hydraulic cylinder and the carrying and loading of goods are supported by the lever frame to achieve a balance. Because of the possibility of overloading and unbalanced loading when handling goods, which often lead to deformation or fracture of the lever frame. Once this happens, the truck cannot operate normally. At this time, you contact the manufacturer or purchase a replacement lever frame.
