Abstract
A self-propelled rotatable hydraulic lift having a body with an extensible boom pivotally attached to the upper rear portion of a counterweight and terminating in a self-leveling workman's platform. Remote lift controls are provided at the platform by means of control lines contained in flexible conduits within the boom. The center of gravity of the counterweight is located between the pivotal connection of the boom and the axis of rotation of the boom to provide both improved stability with respect to back tipping when the boom is extended vertically and a smaller rotational diameter for the lift body.
