High Abrasion Resistance Running wheel
A wheel is a device used to support a crane and load and to reciprocate a crane on a track. The main form of wheel damage is wear, hardened crushing and pitting. The material of the wheel is generally made of ZG430-640 steel. In order to improve the wear resistance of the wheel surface strength and life, tread should be surface heat treatment, requiring surface hardness of HB300-350, quenching depth of not less than 20mm.
