AI Technical Summary

Technical Problem

It is difficult to install elevators in existing old residential buildings. Traditional shaft structures occupy space and affect lighting and ventilation. Traction elevators are limited in the application of shaftless designs. Furthermore, direct-pull elevators consume a lot of energy and have high maintenance costs.

Method used

Design a modular elevator retrofit structure, which adopts wall-mounted guide rails, counterweight modules, car, traction machine and wall-mounted platform, combined with traction steel wire rope, to realize the modular installation and operation of the elevator, avoid the traditional shaft, adopt traction energy-saving technology, and equip with anti-fall components to ensure safety.

Benefits of technology

It enables convenient installation and maintenance of elevators, saves space, does not affect building lighting and ventilation, operates stably and saves energy, reduces maintenance costs, adapts to different floors and load requirements, and ensures passenger safety.
