ABSTRACT:
An article handling/supporting apparatus having a frame, a resolvable base attached to the frame, a turntable assembly mounted to the base, a main boom pivotally connected to the turntable assembly and a main article supporting arm pivotally connected to the main boom. Upon the release of a plurality of locking mechanisms, the turntable assembly is free to rotate while the main boom and the article support arm are free to move up and down. Once an operator has positioned the article handling/supporting apparatus in the desired location, the operator, by the release of a single button, can lock all of the movable components of the apparatus. In addition, fine adjustment of the components can be made from a single location by an operator even after the components have been locked in place.
