Abstract: To provide convenient positioning of a subject in a wheelchair, the apparatus has a wheelchair support bucket with two wheel tubs which are connected by an axle. The wheelchair is pivotable in the bucket about the axle for tilting of the occupant. The axle is mounted to a frame which is elevatable on bearings, and the frame runs horizontally on tracks, and is rotatable. The bucket tubs have semi-cylindrical surfaces which position the wheelchair with the wheelchair brace frontward of the housing. The movement mechanism is thus able to be compactly positioned with respect the wheelchair, for convenient positioning of subjects for hair care, dentistry, or other operations. Tilt locks are provided on each bucket tub to passively prevent the egress of a wheelchair from an elevated or tilted bucket.
