Hand pallet trucks are undoubtedly the most common handling tool in modern logistics, and they can be found in large and small factories. The application is also very wide, used in various industries such as postal service, airport, warehouse, workshop, supermarket, logistics and so on. In a modern society, material handling has been inseparable from the manual pallet truck, which is also called the 'king of the 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 that have individual needs has gradually increased. In order to meet market demand, manual pallet truck manufacturing has also appeared in the market such as: extended manual Various types of trucks such as trucks, widened manual trucks, large-tonnage manual trucks, scissor manual trucks, electronic scale trucks, electric trucks, etc., continue to meet market demand. However, all types of manual pallet trucks are faced with such a problem, that is, the problem of after-sales service and maintenance of manual pallet trucks. '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, so solving the after-sales service maintenance problem is the guarantee for the continuous operation of the manual pallet truck. Next, the editor of Niu Li will give you an analysis of the most problematic parts of manual handling and how to solve these problems. No more nonsense 1. 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, and no matter how good other parts are in time, it will not be possible to work without any damage. The oil pump is composed of a lot of parts. Among them, dust-proof rings, O-rings, steel balls and other accessories are the most prone to problems. Once problems with these accessories are found or they are worn or damaged during use, the most The easy and fastest solution is to replace and replace these accessories. 2. Oil cylinder The oil cylinder plays a vital role in the whole lifting process of the truck, and it is also used to realize the rising and falling of the goods. Therefore, if the fork cannot be lowered, or cannot be raised, the reasons: 1. The piston rod and the oil cylinder may be damaged due to overload or partial load when the goods are being carried; 2. The piston rod is exposed for a long time and rusts and hinders To ensure the smooth movement of the piston; 3. The adjusted nut and hex nut are not in the correct position; at this time, according to the judgment, replace the piston rod or cylinder, reduce the truck to the lowest level when the truck is not used, and re-adjust 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 of the oil cylinder is found, check it in time. If the sealing ring is aging or damaged, replace it with a high-quality sealing ring. 4. Wheels The wheels are a kind of wear and tear, and they will wear out after long-term use. The wheels of the trucks are also divided into many types, such as nylon wheels, PU wheels, polyurethane coated nylon, rubber wheels, bakelite wheels. Wait. 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 truck wheels in time if they are worn to a certain degree. The expensive or cheap ones are available for customers to choose. 5. Lever frame The lever frame is a 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 all supported by the lever frame to achieve a balance. This may occur when the goods are being transported. Phenomena such as overload and unbalanced load often lead to deformation or fracture of the lever frame. It must happen that the truck cannot work normally, so contact the manufacturer or purchase and replace the lever frame in the market.
