A lifting device, in particular for lifting and lowering loads, vehicles or similar, having a vertical lifting column, having a support arranged on the lifting column, which is guided by a guide on the lifting column and is able to be driven vertically along the lifting column, having a drive device for lifting and lowering the support and a load receiver arranged on the support, wherein the load receiver is able to be driven over and has a drive-on region, a support region and a drive-off region which are arranged in a row along a mutual axis in the drive-over direction and the load receiver has a holding arm outside of the support region and outside of the drive-over direction of the drive-on region or drive-off region.

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.

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 low-profile trailer jack for preventing damage to a jack includes a jack module that comprises a plurality of nested sections so that the jack module is selectively extensible. A first coupler is coupled to the jack module. A second coupler is coupled to an upper face of a hitch assembly proximate to an orifice that is positioned through the hitch assembly. The second coupler is complementary to the first coupler. The jack module is configured to be inserted into the orifice, positioning the second coupler to couple to the first coupler to fixedly position the jack module within the orifice. A top of the jack module is positioned proximate to the second coupler. An actuator is operationally coupled to the jack module. The actuator is positioned to extend the nested sections so that a bottom of the jack module contacts a surface to elevate the hitch assembly.

A jack has a lifting post, a pair of side legs, adjustable leg extensions, and leg locking mechanisms for locking the leg extensions with respect to the side legs. The lifting post has a bottom element and a top element that slide with respect to each other, and a vehicle engaging hook mounted on the top element. A lifting mechanism lifts the top element with respect to the bottom element, once the side legs have been adjusted.

An adjustable positioning device includes a connection member, a positioning member and an adjusting member threaded onto the connection member and an adjustment structure including two protrusions respectively located on the positioning member and the adjusting member to face toward each other and an abutment surface extending upwardly and circularly from the bottom side of one protrusion toward the other protrusion. Subject to the design of the adjustment structure, the user can conveniently adjust the position of the positioning component set on the connection member to produce a positioning effect, or a positioning and tamper-proof effect.

A wood flooring adjustment and assembly tool includes a stationary flat bar having a distal end provided with a downwardly oriented lip, a guide statically attached to a top surface of the flat bar and located proximally of the downwardly oriented lip, a dynamic bar slidably positioned through the guide and linearly reciprocated along the stationary flat bar wherein the dynamic bar has a plate affixed to a distal end thereof, and a lever having a bottom end pivotally positioned at a proximal end of the stationary flat bar and directly abutted against a proximal end of the dynamic bar. Such a lever is pivotal about a fulcrum axis registered orthogonal to the proximal end of the stationary flat bar. The downwardly oriented lip is registered orthogonal to a longitudinal length of the dynamic bar and parallel to the flat bar.

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 versatile lever-type decking and plank removal tool for more efficiently prying floor-boards from deck foundations and floor-joists to which they are nailed. The decking and plank removal tool uses an adjustable demolition head having an offset inverted hook to tear off any deck board in any configuration in seconds with a minimum of effort, allowing the user to remain completely upright for the entire process. An optional vibratory-assist module is also disclosed.

A lifter includes a support base, a first elevating stand assembly, a first elevating-drive mechanism, a turning-drive mechanism and a bracket mechanism. A lower portion of the first elevating stand assembly is provided with two sets of first fixing racks. The support base is symmetrically mounted on the first fixing racks. One side of the first elevating stand assembly is provided with a first elevating-drive mechanism. A first elevating stand is installed inside the first elevating stand assembly. The first elevating-drive mechanism drives the first elevating stand to move through the transmission mechanism. The turning-drive mechanism is provided with a support base. One end of the support base is hinged to a movable support frame. The other end of the support base is provided with a locking assembly. The turning-drive mechanism is provided with a bracket mechanism.
