*Cylinder: The cylinder plays a key role in the lifting of the truck. The lifting of the goods is also realized by it. If the fork cannot be lifted, it is very likely that there is a problem with the cylinder, and the cargo is overweight or there is no cargo. Putting it in the middle position will cause serious damage to the piston rod in the oil cylinder or the oil cylinder.
When not in use, the piston rod is exposed to the outside for a long time, causing rust and making the piston inflexible. Check and judge the situation and replace the cylinder or piston rod.
*Oil pump: This is also a key part of all hydraulic equipment, such as: manual hydraulic pallet truck. As long as the oil pump fails, the entire pallet truck cannot be used. As long as any component of the oil pump is found to be damaged, it must be replaced immediately. For example: sealing ring, steel ball, dustproof ring, etc., if not replaced in time, it may damage the entire oil pump.
*Oil seal: The part that makes the connection between the cylinder tube and the piston rod airtight is the oil seal. This part generally uses imported seals, because it has good sealing performance and wear resistance. It is often seen on the Internet. People ask about the oil leakage of the oil cylinder. The possibility of this cause appearing on the oil seal is very high. It is recommended that if there is an oil leakage problem, you can check the oil seal.
