A lift device includes a chassis, a boom pivotally coupled to the chassis, a first leveling assembly pivotally coupled to a first end of the chassis, a second leveling assembly pivotally coupled to an opposing second end of the chassis, and a control system. The first leveling assembly includes a first pair of actuators positioned to facilitate a first pitch adjustment and a first roll adjustment of the first end of the chassis. The second leveling assembly includes a second pair of actuators positioned to facilitate a second pitch adjustment and a second roll adjustment of the opposing second end of the chassis. The control system is configured to (i) actively control the first pair of actuators and the second pair of actuators during a first mode of operation, and (ii) actively control the first pair of actuators and facilitate passive control of the second pair of actuators during a second mode of operation.

A lift arm of a floor jack is composed of a number of components made from metal bar stock. The lift arm is adapted to transfer power and motion from a power unit to a saddle, which is adapted to be placed at a lift point of the vehicle, thereby applying pressure to the lift point and raising the vehicle.

A jack stand apparatus for use with commonly available jacks, particularly for vehicles with insufficient surface area for both jacks and jack stands to be used on the specified lifting points. In one embodiment, the jack stand comprises an axle assembly, a lift pad assembly, a plurality of height adjustable leg assemblies where the leg assemblies may be rotated with respect to the axle assembly, and a leg locking mechanism. In one embodiment, the foldable device is collapsed into a planar orientation, and positioned on top of a jack's lifting plate; passed under the vehicle, including low profile and limited clearance vehicles. Once the apparatus and vehicle are lifted with the jack, the legs of the apparatus are locked into position to support the lifted vehicle, and the jack is safely removed.

A levelling group of an aerial work platform includes: a support base for supporting a containing cage of an aerial work platform, a support frame hinged to the support base so as to be able to oscillate with respect to an oscillation axis, at least a pair of ground rest elements hinged independently to the support frame, with respect to respective articulation axes parallel to one another and substantially perpendicular to the oscillation axis, such as to be able to independently vary a height thereof with respect to the support base.

A stabilized jack assembly is a device utilized to elevate and stabilize a vehicle. The device eliminates the need for the user to venture beneath the vehicle before the vehicle is stabilized. The device includes a planar base that provides stability for the device on a flat surface. A scissor lift assembly is utilized to elevate and lower a mounting head that is placed into contact with the vehicle. A threaded spindle is axially engaged through the scissor lift assembly and is rotated in order to elevate and lower the mounting head. A plurality of support struts is utilized to stabilize the device once the vehicle is elevated. The plurality of support struts is removably engaged into a plurality of strut braces on the planar base. The plurality of support struts is able to automatically engage the plurality of strut braces when the vehicle has been sufficiently elevated.
