ABSTRACT:
A five-axis production-line handler has a handler shoulder (1) that is suspended rotatively downward from a gantry chassis (2). Two handler columns (4, 5) are spaced apart and suspended vertically downward from the handler shoulder. The handler columns terminate vertically above a production-line floor (6) for allowing horizontally circumferential positioning of the handler columns by rotation of the handler shoulder. The handler columns include hoist carriages (9, 10) that are raised and lowered by a hoist (7) for positioning item-rotation axles (11, 12) and attachment plates (29) to receive and rotate production items on an axis between the handler columns. The gantry chassis is gantry-wheel mobile on a gantry rail system for linear travel along a production line that can be linear or looped for a wide variety of production.
