The transport of people and goods over aerial cableways has been in use over the last hundred years for many different applications but published works are still only a few years old. Either by transporting uphill, between a long valley or canyon. Since it is a complex mechanical system with many bodies and subject to environment perturbation, nonlinearity features may appear such as excitation of sub and super harmonics of the cable and cause vibration to the traction mechanism, which can damage the machinery and endanger the operation. For this work, we analyze the effect of those vibrations according to the speed of operation.
