ABSTRACT:
A vibration damping arrangement for a gondola of a type having a supporting unit attached to a cable, a hanger suspended from the supporting unit and a carriage suspended from the hanger. A vibration damping device includes an elongated hollow housing. A bottom plate of the housing defines a downwardly arcuate oscillation track which extends in a direction perpendicular to the cable. A vibration damping body is movably located on the oscillation track such that it can naturally oscillate on the oscillation track in the longitudinal direction of the oscillation track upon vibrations of the carriage. The vibration damping device is located under a seat inside the carriage, suspended from a bottom of the carriage, supported by the hanger above a roof of the carriage or mounted on the roof of the carriage in such a manner that it does not extend beyond width and length of the carriage. The vibration damping device does not substantially occupy a passenger room so that comfortableness is not degraded. A cover may be provided to house the vibration damping device thereby not affecting appearance of the gondola if the vibration damping device is located outside the carriage.
