<p>A mobile aerial lift platform vehicle of the type having an upstanding pedestal (26) and an elevating assembly (22) mounted on the pedestal (26) to raise and lower the work platform (24) while maintaining the center of gravity of the platform (24) within the base area defined by the wheels (14) of the vehicle. The improvement is that the pedestal is pivotally mounted to the chassis (11) of the vehicle for pivotable movement about a first axis extending fore and aft of the chassis (11) and about a second axis extending from side to side of the chassis. Two hydraulic rams (62, 63) are provided, each of which will pivot the pedestal (26) about one only of the axes, so that the pedestal (26) may be leveled even though the vehicle is on unlevel ground.</p> |
