To enhance transport safety and reliability of ropeway systems, it is essential to reduce the swing of the carriers that results from wind, etc. As a means to lessen the swing of the carriers, we will propose damping equipment that uses two balls as the movable mass. We will also discuss the method for adjusting the design parameters for this equipment. Based on a simulation, we will determine the effect of this equipment. In addition, we will refer to the results of a model test to verify the effect of this damping equipment.
