There is no doubt that manual truck is the most common handling tool in modern logistics, which can be seen in large and small factories. It is also widely used in post, airport, warehouse, workshop, supermarket, logistics and other industries. In modern society, material handling has been inseparable from the manual truck, which is also known as the "king of land".
In the process of social development and change, the demand for manual carriers is also changing, and enterprises with personalized needs are gradually increasing. In order to meet the market demand, various types of carriers have emerged in the market, such as extended manual carriers, widened manual carriers, large tonnage manual carriers, scissor type manual carriers, electronic scale carriers, electric carriers and so on, Continuously meet market demand.
However, all kinds of manual carriers are faced with such a problem, that is, the after-sales service of manual carriers is not suitable for maintenance. "Nothing in the world is not bad.". No matter how good the product is, it will be damaged or eliminated. Therefore, solving the problem of after-sales service and maintenance is the guarantee for the continuous operation of the manual carrier. Next, Niu Li Xiaobian will give you an analysis of the parts that are most prone to problems in manual handling and how to solve these problems. No more nonsense
1. Oil pump: the oil pump is the key part of all transporters. Once there is a problem with the oil pump, that is, announce that the transporter stops working. No matter how good other parts are without any damage, they cannot work. The oil pump is composed of many parts, among which the most prone to problems are dust rings, O-rings, steel balls and other accessories. Once these accessories are found to have problems or are worn and damaged in the process of use, the easiest 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 through it to realize the lifting and lowering of goods. Therefore, if the fork cannot be lowered or raised, the reasons are as follows: first, the piston rod and oil cylinder may be damaged due to overload or eccentric load when the goods are loaded; 2、 The piston rod is exposed for a long time and rusted, which hinders the smooth movement of the piston; 3、 The adjusting nut and hexagon nut are not in the correct position; At this time, according to the judgment, replace the piston rod or oil cylinder. When the truck is not used, lower the truck to the lowest level and readjust the nut.
3. Oil seal: oil seal is the key component between the piston rod and cylinder barrel of the sealing oil cylinder. Generally, it is equipped with imported sealing ring. It mainly has good sealing, wear resistance and long service time. 70% of the oil leakage of the oil cylinder occurs on the oil seal. If the oil leakage of the oil cylinder is found, check it in time. If the sealing ring is aging and damaged, select high-quality sealing ring for replacement.
4. Wheel: the wheel of the truck is a kind of worn-out goods, which will be worn out after long-term use. The wheels of the truck are also divided into many kinds, such as nylon wheel, PU wheel, polyurethane coated nylon, rubber wheel, electric Mullen, etc. Most carriers are equipped with nylon wheels because the market is common and the price is cheap, but the wear is poor and the walking noise is also large. The wheels of the truck are worn to a certain extent. Please replace them in time. The expensive and cheap ones are at the customer's choice.
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 handling and bearing of goods are supported and balanced by the lever frame. Overload, eccentric load and other phenomena may occur during the handling of goods, which often leads to the deformation or fracture of the lever frame. This phenomenon must occur, and the truck can not operate normally, so contact the manufacturer or purchase and replace the lever frame in the market.
