The model of a carrying rope under in–service loads is developed to analyze dynamic response of the cable during ropeway operation including: start conditions while carriers leave the station, steady ride, an emergency stop of a system. The pendulum model of a moving passenger carrier is formulated to define loads acting on the cable. Equations of motion of the cable loaded by moving pendulums are derived by applying Ritz approximate method and Lagrangian description of motion. Some numerical results are presented to illustrate applicability of proposed method in an investigation of carrying cable vibrations. (© 2008 WILEY‐VCH Verlag GmbH & Co. KGaA, Weinheim)
