Abstract
Load bars are transferred, in loaded condition, to or from the hangers of an overhead conveyor by a load transfer apparatus having a pair of parallel tracks approaching the power-driven conveyor path perpendicularly. The parallel tracks guide manually movable trolleys toward the power-driven conveyor path. The ends of these tracks nearest the power-driven conveyor are pivotable downwardly. To transfer a load from the manual trolleys to the power conveyor, the power conveyor is stopped, suspension chains of the power conveyor trolleys are hooked to the load bar, and the pivoted track sections are lowered until the suspension chains of the power-driven trolleys bear the load. Suspension chains of the manually movable trolleys can then be disconnected from the load bar, and the manual trolleys are removed from the tracks for reuse. The tracks are designed with flanges which prevent removal of the manual trolleys except at specified locations. A control circuit includes a position switch which automatically stops the power conveyor at a position in which transfer can take place. The circuit also includes safety switches to disable the power conveyor when the pivoted tracks are lowered, and also when manual trolleys are at the transfer location.
