Description

Rail type manned lifting mechanism

Technical field:

The invention relates to an electric passenger lifting device.

Background technique:

The current electric manned lifting devices mainly include vertical elevators, rolling elevators and the like. Because the cost of these two elevators is high and the space taken up during installation is large, they can only be suitable for large-scale public places and high-grade residential buildings. Due to the cost of construction and operation, there are very few occasions where vertical elevators and rolling elevators can be applied, and in more occasions, many elderly people and disabled people need some electric walking aids to help them navigate in certain buildings. Going upstairs, climbing in the park, etc. Therefore, in the real society, there is a great need for an electric manned lifting device with low cost and low operating cost, which can be used in vertical elevators, rolling elevators and other places that cannot be used due to economic cost occasions, but there is no such device at present.
