(1) Machine room section: Composed of components such as the motor, brake, speed reducer, and traction sheave.

A. Traction machine: A driving machine that relies on the friction between the traction rope and the traction sheave to achieve the movement of the car.

B. Control cabinet: This cabinet contains a PC microcomputer and various relays and contactors. Through various control lines and control cables, it connects to the control devices on the car or landing operation boxes to meet the requirements for predetermined elevator operation, automatic control performance, and safety protection performance.

(2) Car: A metal structural component in the elevator used for loading goods. It is driven by the traction rope along the guide rails to perform vertical lifting movements, completing the task of transporting goods.

(3) Hoistway section: A. Guide rails: Components that provide guidance for the elevator car and counterweight.

B. Buffer: A cushioning device installed at the bottom of the hoistway pit below the car and counterweight. It provides a cushioning effect for the car or counterweight in case of overspeed descent or falling due to overload or rope breakage.

C. Counterweight: A device that uses its weight to balance the weight of the car, improving traction performance. It moves vertically along the counterweight guide rails.

D. Limit switch: A device that prevents the elevator car from exceeding a certain position at the upper or lower ends during operation. If the car overtravels,
