Abstract (en)
[origin: ES8307320A1] An excavator can be moved in a step-like manner employing its boom and stepping feet or it can be arranged for conventional driven wheeled movement. The excavator includes a supporting frame with outwardly extending supporting arms on which first wheels and/or stepping feet can be mounted. A superstructure is positioned on the supporting frame and the boom is articulated to the superstructure. A second wheel is supported on the superstructure and can be moved in the vertical direction between an active position resting on the ground on which the excavator is supported and an inactive position spaced upwardly from the ground. With two first wheels on one side of the supporting frame and the second wheel in the active position on the opposite side, conventional three-wheel driven movement can be achieved with the second wheel effecting the steering of the excavator.
