Role of bulldozer roller |China Excavator Track Roller
The roller is mainly used to support the mass of the machinery under the wheel frame and distribute the mass on the track. At the same time, it also relies on its roller flange to clamp the chain rail to prevent lateral sliding (derailment) of the track, so as to ensure that the machine moves along the track direction with "low rolling resistance" and the service time when working in muddy water.
The roller is used to support the weight of the machine and rolls on the track link or the track guide plate. Therefore, it is used to clamp the track to prevent the track from sliding laterally and derailing. The drive track slides laterally on the ground during steering. The road roller sometimes works in muddy water and bears large impact load.China Excavator Track Roller
Therefore, it is required that the rim has reliable sealing, low wear resistance and rolling resistance. Therefore, in view of the fact that the drum must not only bear considerable weight, but also withstand the test of various harsh environments, the quality of the drum is required to be quite high.
