Abstract

The handling mechanism picks up and lifts parallelpiped objects from overhead. It is used for non-magnetisable objects with rough surfaces and may be used in warehouses. The unit uses a series of similar vertically acting piston-cylinder mechanism mounted together a regular intervals in one or both directions on a horizontal plane. As the unit descends and engages the objct, the pistons making contact retract. The pistons beyond the plan area of the object remain extended and move laterally to grip the sides of the object. Some of the piston mechanisms may be equipped with secondary transversely acting piston mechanisms.
