The present invention is a folding jack stand that can be rotated and lifted and is capable of raising heaving machinery from a single point and then locked into a place at the point where it is lifted thus able to raise and hold pressure at the same point.

Embodiments in the present description are provided for a lever adapter device for use in lifting a vehicle or other heavy objects. The lever adapter device includes stabilizing feet and one or more support legs. Each one of the stabilizing feet is attached to an end of each support leg. The lever adapter device further includes a hinge disposed at an end of each support leg. Each support leg is extendable and retractable towards or away from the other support leg. The lever adapter device further includes a jack attachment piece and one or more hinges, which are also connected to the one or more support legs. The jack attachment piece is configured to be removably connected to a jack, such as a HI-LIFT jack, or to other lifting devices to assist in lifting the vehicle or the other heavy objects.

A step chock for stabilizing a vehicle or other object against undesirable movement, such as, during a rescue operation. Embodiments for a step chock includes having two leg portions, one of which angularly rotates with respect to the second with a lever to lock the two leg portions at a specific angle. The step chock is usable in three positions including where the stair-stepped top surfaces of the two leg portions are forced under the vehicle, where the top surfaces of the two leg portions are against the ground and the bottom surfaces are forced under the vehicle, and where the rear surfaces of the two leg portions against the ground and the front surfaces of the two leg portions are forced under the vehicle. Further, the step chock is usable as a fulcrum for a lever and a lever adaptor to lift a vehicle.

A lifting system includes a base and an upright extending from the base. An articulating arm assembly is coupled to the upright. The articulating arm assembly has a platform coupled thereto. The lifting system further includes a prime mover. The prime mover engages the articulating arm assembly to elevate the platform to a desired height.

A method and system for supporting and/or stabilizing a recreational vehicle is disclosed. A cargo stabilization bar, load lock bar, cargo bar, or jack bar is oriented vertically and placed so that the bottom end of the cargo stabilization bar is supported by the ground or other stable base. The cargo stabilization bar is extended so that is the top end of the cargo stabilization bar is at a height so that it can support the recreational vehicle through contact with a support point on the recreational vehicle.

Apparatus for unrolling rolls of building insulation in vertical strips from the roof eave down, and adapted to be carried by an aerial work platform that in turn is carried by an elevator, has a pair of spars as well as an arbor and a tensioning control mechanism. The spars are spaced apart and are mounted to as well as project away from the aerial work platform. The arbor is carried between the spaced spars for inserting through the core of a role of insulation and allowing the insulation to be unrolled from the roll in the form of strips to be hung on the building. The tensioning control mechanism is provided for controlling the unrolling of the roll.
