The function of the roller is to transfer the weight of the locomotive group to the ground and roll it on the track. To prevent derailment, the roller should also be able to prevent the track from moving laterally relative to it. Rollers often work in mud and sand, and withstand strong impacts, the working conditions are extremely harsh, and the rim is easy to wear. The requirements for the roller are: the rim is wear-resistant, the bearing seal is reliable, and the rolling resistance is small.
Our products are according to the standard of OEM to manufacture.
The four wheels refer to: rollers, drive wheels, idlers, and carrier pulleys. One belt refers to the tracks. As the name suggests, the rollers act as support and are located between the lower surface of the left/right beam of the chassis frame and the track. According to the tonnage of the excavator, there are usually 5-10 on one side. The driving wheel plays the role of driving the track, which is fixed on the travel motor, and the drive of the travel motor is transmitted to the track through the gear structure, usually one on each travel motor. The idlers act as guides the tracks, located at the opposite end of the drive wheels, usually two per excavator. The carrier roller plays the role of holding up the track, and according to the tonnage of the excavator, there are usually 1-2 carrier rollers on one side.
