In ropeway transport systems, the swing of carriers caused by a lateral wind is an important vibration problem because of transportation safety and ride comfort. This paper deals with a vibrational characteristics of ropeway carrier models which is suspended from two parallel hauling ropes. The bicable ropeway systems are described by a linear system with two degrees of freedom excited by lateral wind. These dynamical models which both with conventional rigid hangers and with new rotative hangers are analyzed theoretically. The semi-active control method is applied to the rotative hangers model, and carried out computer simulation. These results show that the carrier system using rotative hangers with the semi-active control damper are proved to be effective for reducing vibration.
