The public's cognition of escalators and elevators mainly comes from the different usage scenarios. Escalators are mainly used in large shopping malls and public rail transit. Ordinary elevators are mainly used in houses, sightseeing, hospitals, transporting goods, etc.

From the operating principle. The two ends of the elevator traction rope are respectively connected with the car and the counterweight, and wound on the traction wheel and the guide wheel. After the reducer changes speed, the traction motor drives the traction wheel to rotate. The traction generated by the friction between the traction rope and the traction wheel realizes the lifting movement of the car and the counterweight, and achieves the purpose of transportation.

Escalator: the stairs move horizontally at the passenger entrance (convenient for passengers to climb stairs), and then gradually form stairs; The stairs gradually disappeared near the exit and moved horizontally again. These movements are realized by the cascade main wheel and auxiliary wheel moving along different cascade guide rails respectively. At present, in the escalator field, the heavy-duty escalator independently developed by Dongguan Kuaiyi Elevator has been commercialized, and the escalator was successfully installed for Xiaogan Garden Railway Station in 2020.
