Hydraulic jacks can lift heavy objects and have an inseparable connection with cars. The vast majority of car troubleshooting operations rely on jacks to lift the vehicle to a high place in order to proceed smoothly. However, if the jack is not used properly, various unexpected situations such as the jack slipping may occur, posing a threat to personnel safety.

The main reasons for sudden derailment when hydraulic jacks lift vehicles are:

1. Poor quality of the jack or insufficient load-bearing capacity of the jack, which does not match the tonnage of the vehicle, can cause deformation and other conditions when it cannot be supported, leading to the pulley;

2. The support position of the jack is not selected correctly or the anti slip ability of the top cover of the jack is insufficient;

3. The ground is smooth, and the jack may slide even under load-bearing conditions;

4. Although a jack can lift a vehicle, it cannot lift it for a long time and needs to be used in conjunction with a hydraulic support.

There are many cases of casualties caused by the sliding of vehicles when hydraulic jacks are used to support them. Guanhang Machinery customer service reminds everyone to use the jacks correctly and take responsibility for their personal safety.
