In order to better ensure the safe operation of crane wheel group, the quality must be strictly checked!
A blocks of wheels used to support a crane and a load, and to make the crane move back and forth on a track.
The main forms of wheel damage are wear, hardened layer crushing and pitting.
The wheels are usually made of zg430-640 cast steel.
In order to improve the wear resistance strength and life of the wheel surface, the tread should be subjected to surface heat treatment. The surface hardness is required to be hb300-350 and the quenching depth should not be less than 20mm.
