Description

Technical Field

[0002] Currently, many colleges and universities use actual objects or scaled-down models to demonstrate their learning to students, in order to improve their practical skills and consolidate the theoretical knowledge learned in class. Many colleges and universities use elevator models that are 1:1 scale replicas of real elevators. In an elevator, the traction system's primary function is to output and transmit power, thereby enabling the elevator to operate. The traction system primarily consists of a traction machine, traction ropes, a guide structure, and a return pulley. The guide structure restricts the freedom of movement of the car and counterweight, forcing them to move up and down along the guide rails. The guide structure consists of guide rails, guide shoes, and a guide rail frame.
