By setting up the machine room, traction motor and deceleration device on the top floor of the building, the wire rope is driven to pull the car and the counterweight on the track in the hoistway. run. This driving method makes it possible to run only one car in a single well, and the elevator in the single-car operation mode can still meet the use requirements in low-rise buildings and floors with small passenger flow. With the rapid development of modern cities, high-rise buildings and super high-rise buildings with large population density have sprung up, and the shortcomings of single-car operation mode elevators, such as long waiting time and low transportation efficiency, have been continuously magnified. The operation mode of the car elevator has been difficult to meet the needs of the rapid development of modern urban buildings.

In order to improve the utilization rate of building space and the efficiency of elevator transportation, and reduce the cost of construction and elevators, with the continuous development of engineering technology, a multi-car parallel elevator is being developed and applied.
