The manual pallet truck is undoubtedly the most common transportation tool in modern logistics, and it can be seen in large and small factories. It is also widely used in various industries such as post, airport, warehouse, workshop, supermarket, logistics and so on. In the modern society, the handling of materials is inseparable from the product of manual pallet truck, which is also called "king of land".
In the process of social development and change, the demand for manual trucks has also produced new changes, and the number of enterprises with personalized demands has gradually increased. In order to meet the market demand, manual trucks have also appeared in the market, such as: extended manual Various types of pallet trucks, such as pallet trucks, widened manual pallet trucks, large-tonnage manual pallet trucks, scissor-type manual pallet trucks, electronic scale pallet trucks, and electric pallet trucks, continue to meet market demands.
However, all types of manual trucks are faced with such a problem, that is, after-sales service and maintenance of manual trucks. "There is nothing bad in the world." No matter how good the product is, it may be damaged or eliminated, so solving the after-sales service maintenance problem is to ensure the continuous operation of the manual truck. The following Niu Li editor will explain to friends all the parts that are most prone to problems when manually moving and how to solve these problems. Not much nonsense
1. Oil pump: The oil pump is a key part of all trucks. Once the oil pump has a problem, it means that the truck is stopped and other components are in good condition without any damage. The oil pump is composed of a lot of parts. Among them, the most prone to problems are dust rings, O-rings, steel balls and other accessories. The easiest and fastest solution is to replace and 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 achieve the rise and fall of goods. Therefore, if the fork frame cannot be lowered or cannot be raised, the reasons are as follows: First, the piston rod and cylinder may be damaged due to overload or partial load when the load is loaded; Second, the piston rod is exposed to rust for a long time, hindering The smooth movement of the piston; 3. The adjusted nut and hex nut are not in the correct position; at this time, the piston rod or cylinder should be replaced according to the judgment. When the truck is not in use, the car should be adjusted to the lowest level and the nut should be adjusted again.
3. Oil seal: The oil seal is the key component between the piston rod and the cylinder of the sealing oil cylinder. Generally, the imported seal ring is used. It mainly has good sealing, wear resistance and long service time. And 70% of the oil leakage of the cylinder occurs on the oil seal. If the oil leakage of the cylinder is found, check it in time. If the seal ring is aging and damaged, select a high-quality seal ring to replace.
4. Wheels: Carrying wheels is a kind of wear and tear, and the goods will wear out when used for a long time, and the wheels of the truck are also divided into many types: nylon wheels, PU wheels, polyurethane-coated nylon, rubber wheels, bakelite Lun et al. Most trucks are equipped with nylon wheels because the market is common and the price is cheap, but the wear is poor and the noise is also loud when walking. Please replace the wheels with a certain degree of wear and tear in a timely manner. Expensive and cheap ones are optional.
5. Lever frame: The lever frame is the key component connecting the oil pump and the push rod. The lifting support of the hydraulic oil cylinder and the carrying load of the goods are all supported and balanced by the lever frame. Phenomenon such as overload and partial load often lead to deformation or breakage of the lever frame. This phenomenon must occur and the truck cannot work normally, so contact the manufacturer or purchase a replacement lever bracket in the market.
