There are methods to effectively avoid the breakage of the lifting chain of the stage electric hoist
Improper operation and substandard quality are the main causes of lifting chain breakage. The effective methods to avoid chain breakage are as follows:
1. Improper user operation is mainly reflected in situations such as overloading, diagonal pulling, single load-bearing, and eccentric loading.
It can be applied to the lifting work of heavy objects. Some heavy objects have a relatively large tonnage, and in some working environments, the chain may break during use, which affects the efficiency and safety of operation.
2. The quality does not meet the standard.
For this situation, everyone must identify whether it meets national standards before purchasing and try to choose high-quality and excellent products.
Before use, it is necessary to pay attention to the safety of the inspection. During use, avoid incorrect use, do not overload, and strictly follow the operating procedures to better avoid deformation and fracture of the lifting chain.
Correctly identifying the root cause of the broken lifting chain of the stage electric hoist
The two situations where lifting chains are most prone to breakage are:
1. Brittle fracture. Occurred at the welding interface or weld heat affected zone;
2. Plastic deformation fracture. It occurs at the junction of the straight section of the chain link and the circular ring, where it bears significant shear stress.
The root cause of the fracture is as follows:
Due to substandard manufacturing quality and materials, single chain links may experience brittle fracture or plastic deformation fracture accidents during use.
2. Manufacturing using damaged raw materials is mainly due to issues with materials and heat treatment.
3. Poor welding and heat treatment manufacturing quality.
The brittle material, weak welding, and severe wear of the lifting chain can all lead to insufficient strength and low tensile strength, resulting in the chain being prone to deformation or even fracture.
