Abstract
A washing device (10) includes a chamber (12) with a front door (24). The door is pivotable between a vertical closed position and a horizontal open position. An article carrying assembly (34) is moveable from inside the washing device to an upper surface (26) of the open door. A lifting system (72) moves the front door between lower and upper positions (74, 76). The lifting system includes a follower (154) to which the front door is pivotally mounted. A motor (80) transmits power to a pair of chains (110, 116), which drive the follower along a guide (156) to move the door up and down. Alternatively, the lifting system includes a cable (182) coupled to a fluid cylinder (180). When the door is in the upper position, an operator can move the rack to a transfer cart or load and unload the article carrying assembly, all while in a substantially erect position.
