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.

Cableways have been widely used in industrial areas, cities, and scenic spots due to their advantages, such as being a convenient mode of transportation, time-saving, labor-saving, and low cost, as well as offering environmental protection. To ensure the safe operation of a cableway, based on the characteristic that the velocity of the cableway bracket is approximately zero in a static deformation monitoring environment, a deformation monitoring method called zero velocity update (ZUPT)-based GNSS/IMU tightly coupled algorithm with the constraint of the Earth’s rotation angular velocity was proposed. The proposed method can effectively solve the problem of a single GNSS being unable to output attitude, which is directly related to the status of wire ropes and cable cars. Meanwhile, ZUPT is used to restrain the Kalman filter’s divergence when IMU is stationary. However, the improvements of ZUPT on attitude are not obvious, so the constraint of the Earth’s rotation angular velocity was applied. The performance of the proposed method was evaluated through monitoring the cableway bracket of the Yimeng Mountain Tourism area in Shandong. Compared with the ZUPT-based GNSS/IMU tightly coupled algorithm (ZUPT-TC), the proposed method can further constrain the error accumulation of IMU while stationary and, therefore, it can provide reliable position and attitude information on cableway brackets.

Aerial ropeway is an effective alternative to the conventional modes of land public transport in metropolitan areas and cities. Construction of passenger aerial ropeways in urban environment is a very costly enterprise in terms of engineering and economics, and requires significant financial resources. This article is aimed at the development of the design method of the passenger aerial ropeway, ensuring the reduction in its construction cost. For this purpose, the individual components of the construction cost are considered, and the approximate calculation dependencies are proposed. It is shown that the cost of the aerial ropeway is mainly influenced by the installation step, height of intermediate towers and carrying rope tension. The task of the conditional nonlinear optimization of the given parameters is formulated and solved in the research. This task ensures the minimum cost of the aerial ropeway. The optimization task is done by taking into account possible limitations on the ropeway laying in the severely urbanized environment (the terrain, urban infrastructure arrangement, altitude performance of the urban development, technical characteristics of the carrying rope, etc.). Implementing the solution findings of the given optimization task makes it possible to significantly reduce the construction cost of aerial ropeways in urban environment.
