Background

The inclined hanging type lifting platform provides convenient equipment for old, weak, sick and disabled people using wheelchairs by additionally arranging guide rails on the railings or walls on two sides of the step, and is generally installed in places unsuitable for being used as ramps or lifting elevators, such as subway entrances and exits, underground sidewalks, pedestrian overpasses, railway station entrances and exits, and the like. The inclined hanging type lifting platform does not damage the surface of the stairs, can be folded when not used, does not occupy the space of the stairs, can be used for going upstairs and downstairs by sitting on the wheelchair after the switch is pressed down, and is simple and convenient to operate.

The guide rails are arranged along the stairs, and the inclined hanging type lifting platform slides on the guide rails through the sliding block mechanisms arranged on the back surfaces of the side plates of the lifting platform.
