This is a battery powered, motor driven hand truck with a stated rating of over 800 pounds lift capacity. It handles boxes or other items up or down stairs with ease. The battery lasts for hours between charging. It is like new (really!) and is easy to use. I used it to bring moving boxes out of my basement. The battery lasted all day. The switch on the handle operates the motor driven levers to move the hand truck up or down the stairs. Delivery available.
