WHEEL ADAPTER FOR A MOBILE LIFT DEVICE

摘要

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.

1. A lift device, comprising:
a chassis including a frame; a lift boom rotatably coupled to the frame; a wheel assembly coupled to the frame and selectively reconfigurable between a first configuration and a second configuration, the wheel assembly comprising:
a rim having an inner barrel, an outer barrel, and a lip defining a first surface and an opposing second surface; anda tire mounted to the rim; an axle having a first end coupled to the frame and a second end including a hub; and an adapter plate comprising:
a barrel portion defining a first face and an opposing second face;a hub portion directly coupled to the hub; anda transition portion extending between the barrel portion and the hub portion; wherein the first face of the barrel portion of the adapter plate engages the opposing second surface of the lip when the wheel assembly is in the first configuration and the opposing second face of the barrel portion of the adapter plate engages the opposing second surface of the lip when the wheel assembly is in the second configuration thereby reducing a track width of the lift device.
