Common positions of drag sprockets for construction machinery

In construction machinery, the drag sprocket (also known as the idler wheel) is one of the core components of the "four wheels and one belt" track system. Its main function is to support the tracks and maintain tension, ensuring the smooth operation of the equipment. Common locations are based on the structural design of typical equipment such as excavators

Located on the inclined platform of the chassis X frame ‌ : the drag sprocket is fixed in the sloping area of the X frame (track frame) to prevent the track from sagging or derailing and to reduce the accumulation of soil that may affect the rotational performance.

Coordinated distribution with other track components ‌ : usually arranged at intervals with the idler wheels, guide wheels and drive wheels along the track trajectory to form continuous support points, especially at the key connection points between the mobile and fixed ends of the equipment.

During daily operation, it is necessary to keep this area clean to prevent the accumulation of soil or ice and snow from causing the wheel body to get stuck or the seal to be damaged.
