According to the invention there is provided a double-hinged wheel hanger for hanging a wheel on a hoist arm. The wheel hanger includes a clevis with parallel top plate and bottom plate connected by a perpendicular base plate. In one preferred embodiment the distance between the top plate and the bottom plate is substantially the same as the height dimension of the hoist arm so that the hoist arm can be received between the top plate and the bottom plate, thereby allowing the wheel hanger to be attached to the hoist arm. The wheel hanger has an elongate support arm with a proximal and a distal end. The proximal end of the support arm is rotatably received by a recess in the distal end of an arm-connector by means of a horizontal hinge. The proximal end of the arm-connector is rotatably received between the top plate and the bottom plate of the clevis by means of a vertical hinge. Consequently, the distal end of the support arm is rotatable both in the horizontal plane and the vertical plane. In operation, a wheel taken from a vehicle that has been raised on a hoist is easily placed on the support rod without a service person ever having to bend at the waist to lower the wheel to the floor or, more importantly, to pick the wheel up and lift it back to the level of the hoist. The rim of the wheel is protected from damage by a protective sleeve about the support arm. An adjustment means is provided for making fine adjustments in the position of the support rod
