The operation of jacks is a commonplace issue, and now everyone has a clear understanding of safe and correct operation. However, Shanghai Industrial and Commercial Crane still needs to emphasize the issue of jack bearing for everyone again, which is a problem that everyone has already recognized but will still overlook.

　　When using hydraulic jacks, we always multiply by a coefficient to ensure safe lifting or extend the service life of the hydraulic jack. Of course, using hydraulic jacks at full load is also possible. However, when using hydraulic jacks, we must remember that the weight and tonnage of the lifted object cannot exceed the range of the hydraulic jack's load, which will affect the service life of the separated jack, In severe cases, it can directly damage the separated jack, causing danger such as bottom breakage, cylinder bulging, and oil leakage of the jack; Another issue is that using a separate jack with partial load during use can cause the piston rod in the cylinder to pull and damage the cylinder body, leading to oil leakage and increasing the risk of operation. The correct use of hydraulic jacks not only helps to better use the product and improve work efficiency, but Shanghai Yiying hopes that users should remember not to use hydraulic jacks excessively when using them. This incorrect use not only fails to improve work efficiency, but also brings harm to hydraulic jacks.

　　Lifting operations, be cautious!! I hope everyone remembers
