Extreme Closeup - Walking dragli ...

This video was taken standing underneath the rear of a Bucyrus 2570W walking d...ragline as it took a step backwards. Each step is about 8' and takes nearly a minute. The machine lifts itself up using the shoes mounted on either side and scoots itself backwards dragging the front edge of its tub along the ground as it goes. The tub is the large circular plate the machine sits on. It is 80' in diameter and distributes the 6,450-ton operating weight of the machine over a large area of the ground.
