The purpose of this paper is to study the longitudinal vibration of the hoist rope which is coupled with the vertical vibration of the moving elevator cab in a high-rise building. The analytical model is composed of the hoist rope, the compensating rope with time-varying length and the cab attached at the lower end of the hoist rope. Moreover, the nonplanar motions of the ropes and the cab are considered. As the main result, the following matters regarding the mechanism of the vertical vibration of the cab were clarified. The frequencies of the longitudinal vibration of the hoist rope and the vertical vibration of the cab are the same as that of the vertical vibration of the end of the hoist rope which is caused by the lateral vibration of the hoist rope. The expansion of the hoist rope is larger than that of the spring between the lower end of the hoist rope and the cab when the hoist rope is long.
