Abstract
A lift device includes a wheel assembly coupled to a frame. The wheel assembly includes a rim having an inner barrel, an outer barrel, and a lip defining a first surface and a second surface. The lift device also includes an adapter plate and an axle having a first end coupled to the frame and a second end including a hub. The adapter plate includes a barrel portion defining a first face and a second face, a hub portion directly coupled to the hub, and a transition portion extending between the barrel portion and the hub portion. The second surface of the lip engages the first face of the barrel portion when the wheel assembly is in a first configuration and the second face of the barrel portion when the wheel assembly is in a second configuration thereby reducing a track width of the lift device.
