The swing of a ropeway gondola is easily induced by wind and can be reduced by a dynamic absorber. To maxmize the performance of conventional dynamic absorber, their location should be as high as possible. However, absorbers can not be located at high positions due to interference issues with structures such as towers and stations. To solute this problem, a new type dynamic absorber is proposed in this paper. It reduces a swing of gondola, by making use of Coriolis force which moves in the radical direction. This absorber is more effective when it is located at lower position. The damping force of conventional absorber is proportional to the amplitude of the vibration of main mass, however, the Coriolis force is proportional to the cube of amplitude. Therefore, it is more effective when the amplitude of gondola is larger.
