Common faults and solutions of spiral jacks inventory

Spiral jacks are widely used in industries such as automotive maintenance. However, due to improper operation and other factors, they are inevitably prone to some malfunctions. The following introduces the common causes and solutions of screw jacks:

1. The handle shakes, but the heavy object is not lifted or lowered: This fault is usually caused by the failure of the ratchet assembly at the handle, which prevents the pawl from pushing normally. In this situation, it is necessary to remove the handle mechanism and reinstall the pawl before use.

2. Abnormal noise generated during the process of lifting heavy objects: This is most likely caused by damage to the supporting bearings of the bevel gear. The solution is to disassemble the screw jack and replace it with a new bearing.

3. There is a sense of impact when the handle swings: This phenomenon may be caused by the teeth of the bevel gear breaking. At this point, it is necessary to replace the bevel gear with a new one.

Spiral jacks play an important role in various work scenarios. Understanding and mastering the causes and solutions of common faults can help us promptly troubleshoot problems during use, ensure their normal operation, extend their service life, and ensure the safety and efficiency of work.
