ABSTRACT:
A peripheral, radial surface extends outwardly and upwardly from the bottom surface of a circular tub which supports a walking dragline excavator or like machinery. The extension surface reduces bearing pressure on the tub in both stationary and walking positions, and facilitates sliding of the tub relative to underlying terrain as the equipment is moved. The extension surface is angularly disposed relative to the bottom tub surface so as to be substantially parallel to the terrain during walking movement of the dragline. Thus, the dragline load is distributed over a relatively large area, and the bulldozing effect of the tub's trailing edge is minimized.
