Section View Through Tubes and Drive System

Two steel guide tubes which are custom designed for each stairway support the platform. These tubes contain a continuous loop of wire haul rope that is attached to the upper carriage. This carriage is mounted to the back of the platform through a slot in the upper tube. The drive system, consisting of an electric motor and drive cog, moves the wire haul rope and the wheelchair platform up and down the stairway.
