The complete hoist is fabricated from heavy gauge steel plate. Lift chains are mounted inside the legs and driven by sprockets welded to the top main shaft and secured to the hoist legs via special heavy duty roller bearings. To ensure adequate static and shock load capacities, uses #120 chain having 34,000 pound tensile strength. This provides the hoist with a 20:1 safety factor. For added safety and simplicity, the gearbox is mounted directly onto the main shaft and is protected by a torque
