HGH-3.8. The hoist has flexible power by either CO2 or compressed air and provides approximately 80 to 90 lifts from a single tank of CO2. The "one size fits all" bottle mounting bracket accepts any common CO2 bottle size. A 20 lb. CO2 tank is also available as an accessory, see Related Items below. The hose stetches 16 ft. for added mobility and stores around brackets underneath the platform when not in use. Up and down functions, including the dump valve, can be activated from the patented pistol-grip control handle. The control handle clips to a storage button on the side of the cylinder when not in use. FOB Shipping Point.
