Abstract
A lifting apparatus for a mobile crane work platform comprising a telescopic mast with a base section, and a plurality of vertically movable sections, the work platform being connected by an articulated arm assembly to the highest deployed movable section of the mast, the telescopic mast being collapsible to a lowered position and extensible to a deployed position. The articulated arm is connected to the highest movable section laterally of the axis of the mast so that the arm is outside of a space between the mast and the work platform when in the lowered position to thereby minimize the horizontal length of the lifting apparatus.
