A jack, comprising: a top plate having at least one adapter block mounted thereon and adapted to contact a load; an intermediate plate; a base plate; a first pair of actuators coupled between the base and intermediate plates; and, a second pair of actuators coupled between respective lowered portions of the intermediate plate and the top plate; wherein one of the first pair of actuators is positioned on the base plate on either side of the respective lowered portions; wherein the actuators are operable to move the top and intermediate plates between respective lowered and raised positions to thereby lower and raise the load; and, wherein a top adapter plate of the at least one adapter block is operable to slide between first and second positions across the top plate as the load is raised and lowered to maintain alignment of the top, intermediate, and base plates below the load.

A vehicle lift includes a lift platform which can be selectively moved in a range between one or more raised positions which are level from the front to the rear and a lowered position where the lift platform is tilted for loading and unloading. A vehicle may be supported on the lift platform. The vehicle lift may be arranged in a trailer.

A parking apparatus has left and right vertical stanchions and a parking platform between the stanchions for supporting a parked vehicle. Carriages are mounted to opposite sides of the parking platform and have wheels that engage in channels formed in the stanchions so that the parking platform can be raised and lowered. The channels are configured to widen or tilt toward the bottom ends of the stanchions. These shapes of the channels near the bottom ends of the stanchions are configured relative to the carriages so that the parking platform tilts slightly forward when the parking platform is near the lowest position so that a vehicle can be driven on and off the parking platform. However, the engagement of the carriages and the stanchions cause the parking platform to tilt slightly rearward as the parking platform moves up to prevent the vehicle from rolling off the parking platform.

A lift structure with adjustment assistance optimized based on ergonomics includes a top, a base, an X-shaped cross arm and a gas spring, wherein the X-shaped cross arm includes a first directional arm and a second directional arm; wherein one end of the gas spring rotates around a second rotating shaft fixed relative to the first directional arm, and the other end rotates around a third rotating shaft fixed relative to the second directional arm, and the first, second and third rotating axes being parallel with each other; and wherein at the reference height, in a plane where an axis of the gas spring is located and is perpendicular to the respective rotating axes, the axis of the gas spring is tangent to a circumference centered on the first rotating shaft and having a set radius, with a tangent point being located on the second rotating shaft.

A vehicle lift comprising a column, a carriage slidingly movable along said column, a lift arm hinged to the carriage. The lift arm has a base body, a distal body rotatably mounted to the base body, and a lock with an insert movable between a release position, where the insert allows relative rotation between the base body and the distal body, and a gripping position, where the insert prevents relative rotation between said bodies. The insert is slidingly movable relative to the base body and/or the distal body along a trajectory parallel to at least one of a section of the extension path of the base body and a section of the extension path of the distal body.
