Apparatus and methods for lifting loads are described. The load lift includes a support frame and a lift assembly with main cylinder and at least one standby cylinder connecting a rotatable cross beam with a clamp plate. A rotary actuator assembly is connected to the lift beam to move the lift assembly out of the way while not in use by rotating the lift assembly from a lift position to a standby position.

A vehicle jack configured to provide lifting of either the front end or the rear end of the vehicle wherein the vehicle jack is operably coupled to a winch secured to the vehicle. The vehicle jack includes a frame having a vertical support member wherein the vertical support member further includes a base member secured to the first end thereof. The vehicle jack includes a vehicle attachment assembly that is slidably coupled to the vertical support member and is provided in a first embodiment operable to secure to the rear end of a vehicle and a second embodiment that is configured to be secured to the front end of the vehicle. The first embodiment of the vehicle attachment assembly is configured to operably couple with a frame hitch. The second embodiment of the vehicle attachment assembly operably couples to the front bumper.

A universal use jack for a dolly is disclosed herein. The present invention not only allows one person to lift a trailer tongue but also allows the trailer to be maneuvered slightly right, left, forward or back so the trailer tongue can be positioned over the ball without having to reposition the vehicle. This, and other uses, are detailed in the present disclosure.

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 computer-implemented method, computer program product and computing system for: establishing wireless connectivity with a mortuary device; receiving status information from the mortuary device; and presenting the status information to a user.

A crank assembly for displacing a load includes a motor and a displacement arm assembly. The motor includes a rotatable output shaft that defines a rotation axis. The displacement arm assembly includes a swingable crank arm and a support roller bearing. The swingable crank arm is coupled to the output shaft to swing about the rotation axis when the output shaft rotates. The swingable crank arm defines a pivot end adjacent the rotation axis and an opposite displacement end. The support roller bearing is rotatably supported on the swingable crank arm proximate the displacement end. The support roller bearing is configured to engage the load. The support roller bearing defines a bearing axis, which is substantially parallel to and offset from the rotation axis.

The present invention provides a double parallelogram vertical lifting device comprising a linkage mechanism and a pushing device. The linkage mechanism comprises a first shaft seat, a second shaft seat, a third shaft seat, an upper support unit movably coupled to the first shaft seat and the second shaft seat on both ends, and a lower support unit movably coupled to the second shaft seat and the third shaft seat on both ends. The upper support unit is provided with a first gear, and the lower support unit is provided with a second gear that meshes with the first gear. The pushing device has one end set on the upper support unit and the other end set on the lower support unit. The invention utilizes the interaction of the first gear and the second gear to generate a reaction force, which enables the lower support unit to cooperate with the upper support unit to move up and down synchronously, and achieves the effect of simple structure and large load capacity.
