Abstract

An article manipulator system which is suitable for fixed and translative mounting at work sites including on scaffold assemblies, providing for alignment compensation for scaffold non-alignment, providing for limited movement about two vertical axes, providing movement along a trolley track in a generally horizontal direction, and a gripper for grasping heavy work objects such as masonry construction units. A control handle provides for signals for raising and lowering a lift cable and signals for locking and unlocking brakes on said pivot arms and upon said trolley track.
