Abstract
An apparatus for moving a chamber door between open and closed positions relative to the opening in a sterilizer or an autoclave chamber. The apparatus is adapted to be used with a door system wherein the door is slidably attached to the chamber by support brackets that are affixed to the end of the chamber. A first set of pulleys are attached to the lower corners of the door and a second set of pulleys, arranged perpendicular to and directly above the first pulleys, are attached to the chamber. A cable, having one end thereof attached to a motorized take-up drum that is attached to the chamber, is received on the first and second pulleys so that the door is suspended on two sides by the cable. The pulley and cable arrangement supports and controls the vertical movement of the door without interfering with the support brackets that are affixed to the chamber. The other end of the cable is attached to a weight for creating tension in the cable.
