Wheelchair platform lifts are installed both indoors and outdoors. Wheelchair stairway platform lifts are more common these days.
They are easily erectable and do not require much alteration in the building.
They are noiseless and smooth. They do not cause hindrance to the stair users. Normally rails are attached to walls of the stairway or the stairs themselves and a platform is attached to the rails. These platforms are larger than the wheelchairs.
When the wheelchair user mounts the wheelchair in the platform and presses the button the platform raises along the rails and takes the person to the other end. Normal safety features are built in these lifts. The platform can be folded when the lift is not in use to facilitate easy use of the stair way for others.
Wheelchair van lifts
Van lifts are used for transfers into automobiles. These can be dismantled and folded easily after use.
