WHEEL MANIPULATOR

摘要

A wheel manipulator (1) has a wheeled, U-shaped frame (5) with thereon a vertical guide (7) along which a support (13) can be pushed. There is a ring-shaped disc (19) supported on bearings on the support (13), which can be turned manually. Three shafts (21) are supported on bearings on the disc, on which chain wheels (23) and arms (25) are fastened. A chain (27) is wrapped around the chain wheels (23). Securing elements (33) are fastened on the free extremities (25b) of the arms to secure the wheel (3). The chain (27) with the chain wheels (23) and the hydraulic cylinder (29) form devices for the synchronous turning of the arms (25). There is a large circular opening (41) in the centre of the support (13). The middle of the wheel (3) is freely accessible through this opening (41), so that the wheel nuts and bolts can be easily undone or fastened.
