Abstract
An off-road specialized jack having features making it more able to perform its function in off-road environments. Jacks of the inventive subject matter can include a skid plate, large diameter, non-pneumatic wheels, and, in some embodiments, a lift extender to facilitate lifting high-clearance objects or vehicles. The lift extender can be removably coupled with the jack, and its height can be adjusted according to a user's needs.
Claims14
An off-road specialized jack, comprising:
- a frame;
- a first axle and a second axle, both coupled with the frame;
- a lifting mechanism coupled with the frame;
- the lifting mechanism having an upper surface and a coupling feature, the coupling feature comprising at least two inward protrusions positioned above the upper surface;
- a skid plate disposed on an underside of the frame, the skid plate configured to reduce sinking into soft terrain;
- a first set of wheels coupled with the first axle, wherein the first set of wheels are configured to improve their ability to roll over soft terrain;
- and
- a second set of wheels coupled with the second axle, wherein the second set of wheels are configured to improve their ability to roll over soft terrain.

An off-road specialized jack system, comprising:
- a jack comprising:
- a frame;
- a lifting mechanism coupled with the frame;
- the lifting mechanism having an upper surface and a coupling feature, the coupling feature comprising at least two inward protrusions positioned above the upper surface;
