Crawler transporters are suitable for all kinds of extreme environments and are a versatile driving tool because of their low ground load capacity and the fact that they use tracks as a walking device and do not require roads. At the same time, they provide sufficient traction for off-road performance. These advantages determine the wide range of applications for tracked transporters in real life.

The running gear used in tracked transport vehicles is significantly different from that of wheeled vehicles, which determines the huge differences in steering principles and steering performance. Compared to wheeled vehicles, tracked steering has the following characteristics.

1. Tracked transporters take up less space to steer, with double tracked transporters achieving a zero turning radius.

2. The ground resistance of a tracked vehicle when turning is greater than that of a wheeled vehicle, as the tracks on the ground are subjected to longitudinal ground resistance as well as lateral resistance.

3, The power of the tracked transport vehicle through the transmission system to travel device speed difference to achieve steering, its steering trajectory is less controllable, because the actual speed of the travel device does not depend entirely on the control input, but also with the nature of the ground.

The actual steering process of a tracked transport vehicle involves slipping of the outer tracks and slipping of the inner tracks, if there is no slipping of the tracks then the track traction will also disappear. This is because track traction is generated when the tracks shear the ground, and the necessary condition for the tracks to shear the ground is slippage. Therefore, the actual steering of the vehicle must take into account the effects of track slip.
