ABSTRACT:
An articulated arm type machine, such as an excavator, has a boom articulated for motion in a generally vertical arc, a stick articulated onto the distal end of the boom, and a tool mounted at the distal end of the stick. The stick is connected to the boom by a quick-disconnect shoe that is rockably mounted at the distal end of the boom and a mating fitting mounted at the proximal end of the stick. A pair of grab hooks on the shoe are used to pick up the stick fitting by hooking onto a grab pin mounted thereon. A set of gear tooth racks on the quick-disconnect shoe intermesh with a corresponding set of gear tooth racks on the stick fitting, and these eliminate play between the stick and boom.
