[0002] The guide wheel is used to guide the direction of soft linear objects such as soft pipes, steel wires, nylon ropes, etc. during their movement. The guide wheel has a pulley structure, and in some projects or products, the guide wheel can save effort. The guide wheel accessories are important components of the electric shovel travel system, and their performance plays a decisive role in the stability, safety and reliability of the entire electric shovel travel system. The guide wheel plays the role of tensioning the crawler in the travel system, so it is also called a tension wheel or a tensioning wheel. It can effectively adjust the tightness of the crawler and effectively achieve smooth and efficient travel of the electric shovel.
