A jack support apparatus has an outer tube having an outer tube body with an outwardly-extending outer tube jack cradle and an opposite outer tube opening, an inner tube having an inner tube body with a plurality of spaced-apart inner tube holes and an outwardly-extending inner tube jack cradle, the inner tube body slidably received within the outer tube body through the outer tube opening, the outer and inner tube jack cradles configured to each selectively engage one of the wheel axle and the cup axle of the jack, a tube spring operable between the outer tube body and the inner tube body to bias the outer tube and the inner tube apart, and a pin operable through an outer tube hole for selectively engaging any of the plurality of inner tube holes, the pin being biased inwardly toward the inner tube by a pin spring.

The present invention relates broadly to a floor jack and a multi-component trunnion assembly that transfers motion of a power unit to the lifting arm of the jack. The end block may include one or more trunnions that are coupled to the block. The trunnions may engage and be coupled to one or more connection plates coupled to the lifting arm of the jack. A hydraulic power unit, including at least one piston may be coupled to the trunnion block for lifting the lifting arm of the jack.

A tire lifting assembly used to remove and replace a wheel and a tire on a vehicle is disclosed. The tire lifting assembly is configured to take the weight of the wheel and the tire when the service technician removes or replaces it thereby eliminating the need for manual efforts from a service technician. The assembly is rolled under the mounted wheel and tire and quickly adjusted to secure the wheel and tire by using a roller platform. A scissor jack mechanism is used to adjust the height of the roller platform which allows the rotation of the tire during the mounting procedure.

A floor jack and a frame therefor including a pair of arched side plates, hubs, axles, and spreader bars are provided. A first pair and a second pair of hubs are positioned at front ends and rear ends of the arched side plates respectively. A first axle and a second axle connect the arched side plates to the first pair and the second pair of hubs at the front ends and the rear ends of the arched side plates, respectively, using pairs of adjustable collars that pivot between lower and upper positions. The spreader bars separate the arched side plates along their length. The frame is configured for use in a conventional jack or in a mega jack to provide increased elevation by fixing the axles to the lower or upper positions of the adjustable collars. A frame is also provided for a fixed height floor jack including non-adjustable collars.
