How does the excavator aluminum belt turn in place?
When the mechanical steering, separate driving force on the side of the track of unilateral, separation power can not overcome the ground friction due to the relative motion in a static state; and the other side of the track with power in motion, its trajectory is a circle, this is equivalent to us so we use your compasses to draw a circle; see mechanical steering.
Because of the difficult turning of the track, the excavator's track turn in situ makes the excavator turn.
This is how it works1. Support the front half of the track with the bucket, so that half or more of the track is out of the ground2, turn the operating lever in the opposite direction of the desired turn, and then turn the track
