The traction cable is a looped structure, part of which is wound around the driving roller of the driving portion, and the driving roller drives the traction cable to circulate and slide on the pulley of the tower, thereby driving the trolley of the transportation portion to realize uphill and downhill operation.

[0004] Such cableway system does not need to excavate a large number of convenient roads, can cross complex terrain such as valleys and steep slopes, reduces the damage to mountain vegetation and ecology, and is especially suitable for line erection in forests or protected areas.

[0005] A single cableway can transport 0.5-5 tons of materials at a time, the transportation speed is stable, and the material falling is avoided through the braking system and the sensor. Compared with the traditional manpower carrying or mule transportation, the efficiency is several times higher, the labor amount is greatly reduced, and the safety risk is greatly reduced.

[0006] Personnel are arranged at both ends of the cableway, the trolley is hung, and then the materials are hung on the trolley; after the trolley reaches the other end, the materials are unloaded, and the empty trolley is transferred from one load-bearing cable to another load-bearing cable. At present, most of the transfer process is carried out manually, and the operation is not very convenient, so it is necessary to improve the cableway system, reduce the difficulty and labor intensity of the empty trolley transfer, and improve the efficiency.
