1. Equipment overview

The door system installation tr--ning platform is a tr--ning platform suitable for various elevator door system installation based on the elevator installation process and m--ntenance requirements, combined with the current elevator market's door system structure. Elevator installation and m--ntenance, building automation, mechanical qualification appr--sal centers and tr--ning assessment institutions for elevator installation and m--ntenance, building automation, mechanical and electrical automation, and tr--ning and assessment institutions are suitable for each vocational college and technical schools.

The entire device is composed of a fixed frame, a movement frame, a door system, and a sedan door system. The unique design enables the layer door and the sedan door to be separated separately, and the frame can be merged to achieve the link between the sedan door and the layer door. Allow students to intuitively understand the structure of the elevator door system, and more effectively help students master their working principles, and make it more convenient to carry out actual installation and m--ntenance.
