The guide wheel is used to guide the track to properly rotate to prevent it from deviating and derailing. Most excavators also function as track rollers. This can increase the contact area of the track to the ground and reduce the ground pressure.
The guide wheel is used to guide the track to run correctly, which can prevent its deviation and derailment. Most of the guide wheels also serve as supporting wheels. This can increase the contact area of the track to the ground and reduce the specific pressure. Most of the wheels are made of smooth, with a shoulder ring in the middle for guidance, and the two sides of the ring can support the track chain to serve as supporting wheels. The inclination of the sides should be small. The smaller the distance of the wheels, the better the performance of the guide wheels.
