One type: The fracture of pneumatic hoist components is one of the main forms of component failure, and fracture 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.

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

Three types: deformation of pneumatic hoist parts. 

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

Four types: corrosion of pneumatic hoist parts. 

Under the action of surrounding media, the wear mainly caused by chemical or electrochemical reactions on the surface of pneumatic hoist parts is called corrosion wear. 

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