By means of describing the characters of manifold different ropeway man car in coal mine,this paper introduced the way to developing a new type long distance and high transporting capacity superterranean ropeway with suspending-chair device which can be hung and carried down in the narrow section and undulate tunnel underground coal mine.

A dynamic model of overhead cable for ropeway is developed, i.

A dynamic model of overhead cable for ropeway is developed together with differential equations of its vibration and initial and boundary conditions.

The analysis of shaking reason for the pedestrian bridge in chongqing and comparison of the reinforcement method;

Based on the similarity of flexibility and bending moment,the exact method for allinclusive flexibility diagram of cableway under multiple load is studiedCompared with the results of exact method,the error of two approximate methods are discussedThe influence of load upon error and the number of load are discussed also

Catenary algorithm is regarded as a theory which is much close to the truth in cableway design.
