  • Patent number: 9067770
    Abstract: A portable compressed gas powered lift, said lift possessing an inner and outer frame of a scissor design. The frame possesses rollers, allowing said frame to roll on a surface. Compressed flexible gas bags are mounted to upper and lower gas bag mounting plates, which are correspondingly mounted to the scissor frame. A lifting bar with adjustable lifting arms is mounted to the top of the scissor frame. As a compressed gas is introduced into the flexible gas bags the flexible gas bags expand causing the scissor frame to expand and lift vertically. The compressed gas is controlled by a flexible line, from the flexible gas bags, to a compressed gas control valve, said valve being mounted to a Tee handle.
