THREE ADVANTAGES
Greener
Old residential buildings are dense, and odor and pollution are not easy to discharge; Yongri elevator site does not need welding, painting, pollution-free, odor-free, and more environmentally friendly;
Safer
The firefighting facilities in old residential areas are not perfect, and on-site welding is prone to fire risks; Yongri Elevator is standardized in production, and the elevator steel shaft is welded by robots in the factory, which is safer without welding on site.
Fast construction
The old elevator has a narrow space, and the slow installation progress will bring a lot of inconvenience; Yongri elevator standard parts are assembled, and the on-site construction is fast, which has no impact on the owner's life.
