The rider faces down the stairs when riding up or down. The seat swivels 180 degrees to allow the user to get on and off at top and bottom landings. The lift has a powder coat finish. Safety features include sensors in the footrest, a locking mechanism in the seat belt, a motor with instant reversing capability, automatic limits at each end of the aluminum track, mechanical and electrical slack cable safety devices, a fail-safe mechanism that prevents operation until the seat is in the correct position, and call stations for top and bottom landings. Call stations can be mounted to the wall or to the floor. POWER: Uses a 110 volt alternating current grounded outlet. DIMENSIONS: Seat is 24 x 18 inches.
