Technical Field

[0002] An elevator is a permanent transportation device that serves several specific floors in a building and whose car runs on at least two rows of rigid rails that are perpendicular to the horizontal plane or have an inclination angle of less than 15° to the plumb line. It is a fixed lifting device that serves specified floors. A vertical lift elevator has a car that runs between at least two rows of rigid guide rails that are perpendicular or have an inclination angle of less than 15°. The size and structure of the car are convenient for passengers to enter and exit or load and unload goods. It is customary to use elevators as a general term for vertical transportation tools in buildings regardless of their driving mode. Counterweight is a component of the elevator traction system. Its function is to reduce the power of the traction motor and the torque on the traction wheel and worm gear. There is no fixed form for the structure of the counterweight, but no matter what form it is, four guide shoes should be set at the four corners of the counterweight to ensure that the counterweight runs vertically along the counterweight guide rails when the elevator is running. The counterweight device is located in the hoistway and is connected to the car through the traction rope via the traction wheel. During the operation of the elevator, the counterweight device slides on the counterweight guide rails through the counterweight guide shoes to balance the elevator.
