ABSTRACT:
A lifting device includes a jack having a first portion and a second portion movable relative to the first portion. A coupling is fixedly attached to the second portion for movement relative to the first portion, the coupling extending away from the second portion and having a configuration for selective attachment to a receiver hitch. The second portion may be moved relative to the first portion with a handle. The lifting device includes a sleeve coupled to the coupling for movement with the sleeve. Support tubing may extend through the sleeve for contact with the ground. This tubing may be locked into place relative to the sleeve. With the tubing, sleeve, and coupling locked into place, a vehicle will be upheld if the jack portions fail. The lifting device may also include a bumper attachment for raising a vehicle that does not have a receiver hitch.
