It is a mechanism that allows vehicles to move using tracks. They increase the contact surface of the vehicle with the ground – reduce the unit pressure and improve the road passability. The caterpillars are of course used in excavators, but also in tanks, bulldozers and armored personnel carriers. In general, tracks are used on machines that maneuver over unrestrained surfaces. The basic track system consists of an endless track belt which surrounds the load wheels. Most designs include a track drive wheel and a guide wheel separately. Additionally, support rollers as well as a tension wheel can be used.Caterpillar Track Roller 302.5C 234-6206, 266-8793  386-0791 Caterpillar 302.7D Bottom Roller
