Abstract: A work transfer system conveying a work basket in a programmed sequence to the processing tanks of an assembly thereof placed at various positions on a work bench. The system acts to transfer the basket to a selected tank and to properly orient the basket with respect to this tank before lowering the basket therein for processing during a given dwell period, at the conclusion of which the basket is hoisted from the tank and transferred to another tank where the procedure is repeated. Running along the front of the bench is a rail on which a robot is driven to a position in the proximity of the selected tank, the robot supporting a hoist which can be raised or lowered. Cantilevered from the hoist and extending transversely across the bench is a hollow arm having a trolley therein provided with a turntable whose spindle projects upwardly to join the upper end of a loop which encircles the arm, the loop being provided at its lower end with a hand that engages the work basket.
