The requirements for the load capacity of the elevator are also increasing, and the demand for the supporting capacity of the elevator is also increasing. More and more large-scale equipment, logistics or goods need to be transported in the vertical direction. In the current large-tonnage freight elevator, the drag The traction system mainly adopts the 2:1 or 4:1 traction ratio winding method, which has higher requirements on the bearing capacity of the host, safety gear, and guide rails, and also brings unnecessary mechanical loss and power consumption. Therefore, elevators with traditional traction ratio structures are only suitable for elevators with not too large loads. When large-tonnage elevators are required, the existing elevators with traction ratio structures such as 2:1 or 4:1 are also used. , wire rope, etc. can not meet the requirements of use, there is a greater safety risk.
