An ATV jack may include an adjustable jack leg and an engagement member configured to engage a bracket disposed on an ATV to non-pneumatically lift the ATV to enable changing of a tire.

A jack for installing a mine stopping panel includes an extendible post and a press for extending the extendible post. The press can have a lever movable between an actuated position and a non-actuated position and operative to extend the post as it moves toward the actuated position and retract the post as it moves toward the non-actuated position. A yieldable biaser yields when the post is extended to extend the mine stopping panel and the mine stopping panel engages a mine surface with sufficient force to crush a stopping seal and anchor the stopping panel. The press can comprise an over-center toggle linkage.

An apiary system includes a platform having a top surface on which one or more beehives are secured, the platform having a floatation device incorporated into the platform; one or more anchoring poles inserted into the ground, the one or more anchoring poles engage with the platform such that the platform can rise and lower along an axis of the one or more anchoring poles; the platform rises above rising water via the one or more anchoring poles.

A diving board lifter and diving board assemblies for lifting a board to a raised position and lowering the board to a dive position. The lifter can mount between a fulcrum assembly and a rear anchor and along an alignment rod of a diving board stand. The lifter can include redundant primary and secondary mechanical safeties for locking the board in a raised position. The lifter can employ a lead screw that moves a linkage including a carriage, a pivot arm, and a pivot shaft to raise and lower the board. An extension shaft can be retracted when the lift is lowered so that a board support member of the lift is spaced below the board. The diving board assembly can include a fulcrum roller and traction material on the board for roller engagement. The lift can press the board support member against the traction material to lift the board.

A hand lift system for positioning a wheel and tire to be placed on a vehicle hub, the system being made up of two primary components. A first paddle component provides a shovel shaped lever to be placed under the tire to be lifted up to the vehicle hub, with a handle grip to operate the lever arm. A second component provides a solid wedge chock on which the paddle component is placed to act as a fulcrum to the paddle component lever, or to act as a support once the tire is lifted to the appropriate height. The paddle component doubles as a tool for shifting the spare tire or flat tire into place. The chock component doubles as a wheel block for either a tire still on the vehicle or a spare tire that has been rolled to the side of the vehicle for use.

An ATV jack may include a clamping engagement member and a leg which pivots which respect to the clamping engagement member a limited amount to enable the jack to lift and hold an ATV. The leg may telescope to allow the jack to be used at variable heights.

The invention relates to an axle lifting device comprising a load bearing support body; a base portion proximate a lower end of the support body, wherein an upwardly curved portion extends from the base portion, the upwardly curved portion including a plurality stepped formations for frictionally engaging the ground; and an axle seat proximate an upper end of the support body, to support or accommodate the axle of the vehicle or trailer, wherein the axle lifting device can rotate on the curved portion between a lowered position and a lifted position, wherein the axle seat extends substantially upright with respect to the ground with the base portion engaging the ground, for lifting the axle off the ground, with the stepped formations functionally and sequentially engaging the ground as the axle lifting device moves between the lowered and lifted positions
