In one embodiment, a roller jack includes: caster wheel attached to jack lift attached to an angle member having an angle member opening, and a locking mechanism to releasably lock the angle member to a corner block of a container through an elongated opening of the corner block. The locking mechanism includes: a locking mechanism baseplate having a baseplate protrusion, a swivel locking plate to be inserted through the angle member opening and the elongated opening of the corner block to the interior of the corner block, and a locking bolt for moving the swivel locking plate to an engaged position, where the swivel locking plate is prevented from passing through the angle member opening and the elongated opening of the corner block, and for threadingly moving the swivel locking plate toward the locking mechanism baseplate to press the angle member and the external wall of the corner block together.

Automated jackstand systems and methods deploy a jackstand to support a front end of a trailer parked at an automated loading dock. The jackstand prevents collapse of the trailer's landing gear and prevents upending of the trailer during loading and unloading. Advantageously, by deploying the jackstand automatically, presence of personnel in the yard where tractors and trailers are moving is not required.

Disclosed is a lifting device, lifting system and method for lifting a vehicle. The lifting device includes a frame with a moveable carrier that is configured for carrying the vehicle; a drive which acts on the carrier and is configured for raising and/or lowering the carrier relative to the frame; a height sensing system that is configured for directly and/or indirectly measuring the height of the carrier; and a locking mechanism for mechanically locking the carrier at a desired height, including a moveable locking element capable of locking and unlocking the carrier. The locking mechanism includes a lock sensor for measuring the position of the locking element.

A portable wheel lifting system to assist in the replacement of a wheel on a vehicle utilizing a portable outer housing, an inner lifting linkage system to hold a wheel or tire in place, and an electrical motor to vertically raise the lifting linkage system and thus the wheel to the desired location.

A parking robot includes a lifting rail, a wheel clamp, and a lift motor. The wheel clamp is disposed on the lifting rail and is moveable from a first position to a second position along the lifting rail. The lift motor is operatively connected to the lifting rail and moves the wheel clamp from the first position to the second position.

A system for a tire caddy and jack device to help a user easily perform tire changes on various-sized vehicles is disclosed. The Tire Caddy Jack is built using a base box supported by a plurality of casters that permits the entire Tire Caddy Jack to be moved easily around an automobile repair facility or garage. A scissor lift assembly is mounted in the center of the top surface of the base box. A scissor lift crank attaches to the scissor lift assembly that when turned will cause the scissor lift assembly to extend upwards, raising the tire and wheel above the ground. The tire and wheel rest upon rollers that are coupled to a pair of twin half roller arms mounted on top of the scissor lift assembly, permitting the tire and wheel to smoothly be raised and lowered to mount and unmount the tire and wheel onto a vehicle. The Tire Caddy Jack supports the tire and wheel while the mechanic removes or replaces the lug nuts or lug bolts that hold the tire and wheel on the vehicle.

A tire and wheel lift assembly for facilitating the removal and installation of wheel/tire assemblies for vehicles includes a rolling frame member that is generally U-shaped, having a center support member and a pair of parallel side support members. A first roller is disposed on a first side support member, and a second roller is attached to a slidable support member so that the rollers are positioned in parallel relation at the same height. The rollers are used to support a wheel/tire assembly, and the slidable support member may slide along the center support member. An adjustment mechanism controls the slidable support member, which can either raise or lower the height of the wheel/tire assembly by sliding the slidable member toward or away from the first roller.
