ABSTRACT:
An excavator-hoist construction vehicle includes an undercarriage with a superstructure supported on it for rotation about a vertical axis. A boom is hinged to the superstructure and supports a tool for digging, lifting or the like. Two pair of supporting legs are attached to the undercarriage, one pair extending forwardly and the other rearwardly. The supporting legs are adjustably movable in the vertical and horizontal directions. Each of the ends of the supporting legs spaced outwardly from the undercarriage are arranged to support a wheel. The wheels on one pair of the supporting legs can be steered and at least one wheel on the supporting legs can be driven.
