The AmeriGlide AC Cargo Lift is a great addition to any storage room, warehouse, manufacturing plant, or other commercial building. This strong and sturdy cargo lift is designed to be installed on an existing staircase and is rated for transporting 350 pound loads. You can customize the track length to fit your staircase and enjoy the security of limit switches that will automatically stop the lift when it reaches the top or bottom of the stairs. (If the track length is 16 feet or longer, the weight capacity is reduced to 250 pounds.) This model runs off of a 115 VAC household current, so all you have to do is plug it into an existing electrical outlet. No major renovations required. When not in use, the space saving platform folds up and out of the way.
