Each type of lifting machinery component has its own service life, so do you know the manifestations of its failure?

Next, I will tell you several manifestations of the failure of pneumatic hoist components:

1： The fracture of pneumatic hoist components is one of the main forms of component failure, and often causes serious consequences.

Moreover, with the high parameterization of cranes, such as increasing power, large capacity, ultra-high speed, ultra-low temperature, ultra-high temperature, etc., 

the probability of fracture failure has increased.

2： There are many main types of wear on pneumatic hoist parts, such as friction wear, abrasive wear, adhesive wear, fatigue wear, micro motion wear, and corrosion wear. 

The common one is still mechanical friction and wear, which is caused by micro unevenness of the surface, peak valley meshing and scraping, or peak plastic deformation and rolling. 

Manifested as changes in size, shape, and volume.

3： The deformation of pneumatic hoist parts is a common phenomenon under working or natural stress, but excessive deformation will cause failure of the parts, such as inability to withstand the specified load, unable to perform the specified function, and interference with the operation of other parts.

4： Corrosion of pneumatic hoist parts refers to the wear and tear caused by chemical or electrochemical reactions on the surface of pneumatic hoist parts under the action of surrounding media. 

It occurs, interacts, and expands with other forms of wear, and can have serious consequences, especially in high temperature and humid environments.
