Three models of battery-powered stackers generate propulsion and lift, eliminating manual lifting and transporting of heavy loads. The stackers' steerable, power drive controls forward and reverse movement at variable speeds. For precision steering in confined areas, the stackers integrate 180-degree hinged construction. A platform model lifts to 80 inches, and a counterbalanced model handles up to 1,000 pounds. A 2,000-pound capacity model lifts to 86 inches. Other features include a spring-loaded mechanism to compensate for uneven floors, automatic emergency safety switch and two sealed batteries.
