Wesco stair climbing hand trucks are battery-powered appliance trucks with aluminium bodies. They are used to transport loads up to 850 lb up and down stairs and are powered by a 1/2 HP electric motor with a sealed rechargeable battery that enables the truck to ascend / descend up to 70 stairs under full load. It includes an auto-rewind rachet that helps in securing the load and two 6-inch mold-on rubber wheels. The industrial-grade gearbox transfers steady power and is better than other drive designs. Wesco stair climbing hand trucks have a dual battery model which offers longer life between charges. A wide range of Wesco stair climbing hand trucks is available on Raptor Supplies, an authtorised distributor of Wesco.
