Gantry crane traveling wheel rail diameter 200 300 400 crane accessory LD traveling wheel

Running wheel is a classification of forgings, mainly used in door crane-port crane-bridge crane-mining machinery According to the use characteristics of driving, the wheel tread is required to have a high hardness, and a certain depth of hardening layer and transition layer (depth> 10mm, hardness HRC40 to 48), in order to improve the bearing capacity, wear resistance and resistance to contact fatigue performance. At the same time, it is required that the matrix organization should have good comprehensive mechanical properties and good tissue state, and the hardness should reach HBS187~229, so that it has high toughness, improve the impact resistance and anti-cracking performance.
