An adapter assembly for lifting a vehicle includes an adapter defining a first pin aperture, a second pin aperture, and an adapter aperture, a first pin, a second pin, and a cross member removably received by the adapter aperture. The first pin is configured to be removably received by the first pin aperture and a first aperture defined by a frame of the vehicle to selectively couple the adapter to the frame. The second pin is configured to be removably received by the second pin aperture and a second aperture defined by the frame of the vehicle to selectively couple the adapter to the frame.

A boom lift includes a base having a first end and an opposing second end, a turntable coupled to the base, a boom coupled to the turntable, an assembly pivotably coupled to the first end of the base, and a first actuator coupled to the first end of the base and the assembly. The assembly includes a tractive element. The assembly extends from the base such that the tractive element is longitudinally offset from and spaced forward of the first end and the opposing second end of the base.

The wheel lift for changing tire on a vehicle (hereinafter wheel lift) is a mechanical structure. The wheel lift forms a jack used to elevate a vehicle such that the wheel of the vehicle can be removed and replaced. The wheel lift is a portable structure. The wheel lift is a rolling structure. The wheel lift is a non-Euclidean structure such that the wheel targeted for replacement can roll onto the wheel lift. The wheel lift comprises a pedestal, a jack structure, and a wheel rack. The jack structure attaches the wheel rack to the pedestal. The span of the length of the jack structure in the vertical direction adjusts such that the jack structure controls the elevation of the wheel rack above the supporting surface. The wheel rack receives and supports the wheel targeted for replacement.
