Aiming at the transport requirements and structural characteristics of double-bearing cable freight ropeway, a pulley type continuous-double-cable freight ropeway is proposed on the basis of the common double load-bearing cable freight ropeway. One wire rope forms two load-bearing cables through the automatic balance device of cable tension. The length of load-bearing cables can be adjusted according to the tension difference of cables during operation process of ropeway. In addition, the roller-type saddle for double-cable freight ropeway is designed to improve the adjustment ability of load-bearing cable. It ensures consistent sag between the load-bearing cables during transportation and avoids overturning of the running car. The calculation of ropeway structure is done according to the actual topography condition, and the loads of the main load-bearing components of the continuous double-cable freight ropeway, such as the automatic balance device of the cable tension, the roller-type saddle and the support leg ropeway, are obtained. The finite element analysis also is carried out on the basis of the loads of ropeway structure. The results show that the components of ropeway meet the structural strength requirement. The continuous-double-cable ropeway can maintain the tension equilibrium of the load-bearing cables, effectively reduce the difficulty of sag adjustment, and improve security in construction.
