An improved protected scissor jack comprises a screw coupled with a screw actuator, that is coupled with a first upper arm and a first lower arm. It also includes a screw tensioner coupled with a screw tensioner end piece, which is coupled with a second upper arm and a second lower arm. The screw is housed within a screw sheath and is coupled to the screw tensioner via threading. The first upper arm and the second upper arm are coupled to a lifting component by pivot joints and interact with each other through synchronizing gears. Similarly, the first lower arm and the second lower arm are coupled to a base by pivot joints and interact with each other through synchronizing gears.

A dual action jack having a hydraulic assembly. Hydraulic assemblies of the inventive subject matter are configured to allow a jack to raise a lifting surface on both the upstroke and down stroke of a jacking lever. Hydraulic assemblies have two pistons that can be compressed to move hydraulic fluid from a reservoir to a ram hydraulic fluid chamber to extend a ram. Each piston has a corresponding checkvalve assembly that allows hydraulic fluid to flow only along a desired pathway. Additionally, a release valve is provided to release hydraulic fluid from the ram assembly, enabling the ram to return to a resting position.
