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.

A jack stand includes a base having a jacking surface which receives a jack thereon, in which the jack has a main body and a lifting head which can be jacked up. Two support columns extend perpendicularly upward from the base parallel to and spaced apart from one another by a fixed lateral spacing to receive the jack therebetween. A jack body is slidably supported along the two columns and includes a jacking surface on a bottom side thereof so as to be arranged to operatively receive the jack between the two jacking surfaces of the jack body and the base respectively such that operation of the jack displaces the jack body relative to the base. A jack post, upon which an object to be jacked is supported, is slidably supported on the jack body to be adjustable in height independently of a height of the jack body.

A manual vehicle ramp jack with an auxiliary hydraulic jack including a pair of parallel tire ramps and a lifter base disposed on the front end of each tire ramp, which has a riser plate movably disposed within a central aperture thereof from a lowered, recessed condition to an alternate raised condition. Each riser plate is provided to receive a tire therein. A manually operated mechanical foot jack is in operational communication and a mechanical hydraulic toe jack is in alternate operational communication with the riser plate of each lifter base. A foot-depressible crossbeam operationally connects the foot jacks together which permits the foot jacks to be operated simultaneously.

A lift device includes a chassis, a primary platform defining a first support surface configured to support an operator, a lift assembly coupling the primary platform to the chassis and configured to raise the primary platform relative to the chassis, and a secondary platform defining a second support surface and removably coupled to the primary platform.

The present disclosure provides a hydraulic jack, including a base as a carrier for mounting other components; an inner cylinder barrel vertically fixed to the base, a sliding cavity being formed in the inner cylinder barrel; an outer cylinder barrel vertically and slidably fitted outside the inner cylinder barrel; a valve plug assembly slidably fitted in the sliding cavity, and the valve plug assembly being rigidly connected to the outer cylinder barrel via a valve plug rod and being able to slide synchronously with the outer cylinder barrel; a valve plug driving assembly mounted on the outer cylinder barrel; and a supporting component mounted on the side wall of the outer cylinder barrel in an up-down adjustable mode. The hydraulic jack of the present disclosure is compact in structure, high in strength, high in load capacity, long in stroke, and safe and reliable in use.

A lift for relocating a toolbox includes a base plate attached to a truck bed having a lifting mechanism mounted thereon. The lifting mechanism is attached to a rectangular support frame that is dimensioned and configured to cradle and grip the bottom wall of a given toolbox. When actuated, the lifting mechanism rotates within a ninety-degree range to move the toolbox from a lowered position, adjacent and parallel to the truck cab, to a raised position, adjacent and parallel to the bed sidewall.

A support assembly comprises a bracket, a blocking member, and a spring. The blocking member is adapted to slidingly move within a through opening of a support member. The blocking member is adapted to be selectively moved from a supporting position to a non-supporting position. The spring is adapted to bias the blocking member towards the non-supporting position. In certain embodiments, the bracket is adapted to retain the blocking member at least partially within the through opening when the bracket is mounted to a hoist. In certain embodiments, the blocking member comprises a handle comprising a pin axially aligned within a compression spring and the bracket comprises a notch adapted to receive the handle.

The present invention relates generally to a DEF tank hydraulic jack adapter plate. The adapter can be fixedly or removably attached to the top surface of an existing hydraulic jack such that the jack can be used to remove or replace a DEF tank from a diesel vehicle. Accordingly, the adapter secures a tank to the plate body of the adapter via a plurality of frame arms which attach to the vertical plates of the plate body. The adapter ensures the tank is retained upon the adapter and subsequently on the jack.

The hoist comprises a base, first and second lower arms, first and second upper arms, and one or more blocking members. The first and second lower arms are pivotally coupled to the base. The first lower arm is pivotally coupled to the first upper arm. The second lower arm is pivotally coupled to the second upper arm. The lower arms and upper arms are adapted to move between an unraised condition to a raised condition. Each of the blocking members is adapted to move between a supporting position and a non-supporting position. Each blocking member, when in the supporting position, prevents the lower arms and upper arms from moving from the raised condition to the unraised condition.
