Apparatuses, systems, and methods are disclosed for providing a zero-G condition to a part to assist in allowing an operator to weightlessly move a part and assist an operator in the installation of a part into an assembly. Present methods, systems, and apparatuses further provide a zero-G lift able to alter the lift velocity of a part, from first predetermined velocity to a second predetermined velocity.

An all-terrain vehicle jack for lifting and all-terrain vehicle wheel off the ground to service it in the field with portable equipment includes an inner tube coupled to a base positionable on a support surface with an outer tube telescopically coupled to the inner tube. A rod is rotationally coupled to the outer tube about a fixed point on the rod and is operationally coupled to the inner tube via a threaded coupling such that rotation of the rod translates the outer tube telescopically relative to the inner tube. A socket adapter is coupled to the rod to facilitate rotation of the rod by an impact driver. An arm configured to abut a lower surface of an all-terrain vehicle control arm is removably couplable at various positions to the outer tube.

A telescopic column includes at least two telescopic elements movable with respect to one another between two end positions and at least one damper that is configured such that, prior to reaching at least one of the end positions, a force slowing the relative movement of the telescopic elements is exerted on at least one of the telescopic elements.

A system and method for supporting vertical members is disclosed. The invention is comprised of an adjustable jack post with angled flanges on each end that allow it to support leaning vertical members, such as but not limited to bent trees and swollen retaining walls etc. The adjustable jack post can be expanded or retracted under load manually by means of a hand crank that engages a bevel and worm gear system located proximally on the post. An object of the invention is to support and/or correct the angle of vertical members. For example, a user wishing to correct a leaning tree after a storm can anchor one end of the post in the ground, brace the other end against the tree and expand the post slowly over time using the hand crank allowing it to grow upright once again.

A portable lifting jack has a drivable mechanism operating a jack shaft formed of telescoping lifting screws. A microprocessor controls power to selectively turn electric motor to drive the operating mechanism. An in-line current draw sensor senses electric load of the motor and communicates this to the microprocessor. One detected electrical load is an electric load spike indicative that the jack shaft has contacted a mechanical load. A potentiometer connected to the operating mechanism senses extended position of the telescoping lifting screws and communicates this position to the microprocessor, which is programmed to derive when snug contact is achieved with an encountered mechanical load and to pause operation of the electric motor. In a synchronized array of jacks, all are paused to await further operator input, which may be coordinated through a remote control.

A telescopic pipe includes a base pipe having a base inner pipe rotated by external force, and a base outer pipe arranged to receive the base inner pipe; a connecting pipe having a connecting inner pipe coupled to the base inner pipe to be extendable to transfer rotational force, and a connecting outer pipe screw-coupled to the inner circumferential surface of the base outer pipe to be extendable; and a finishing pipe including a finishing inner pipe coupled to the connecting inner pipe to be extendable and to be rotated, and a finishing outer pipe that is interlocked by means of rotation of the finishing inner pipe and is screw-coupled to the inner circumferential surface of the connecting outer-pipe to be extendable, wherein the connecting outer pipe is interlocked by the rotational force of the extended finishing outer pipe and thus is extended and retracted along the base outer pipe.
