Patent number: 4531647Abstract: A device for stopping the swinging movement of a load hung by a crane. The crane includes a trolley mounted on an overhead girder of the crane with the trolley being capable of traveling back and forth on the overhead girder. A beam is pivotally supported by the trolley with two sets of sheaves mounted on the beam for displacement relative to each other. Ropes are trained over the two sets of sheaves. A suspension member is provided for suspending the load to be moved by the crane with the suspension member being connected to the lower ends of the ropes. Dampers are mounted between the trolley and the beam. The energy of the swinging movement of the load is converted, through the sheaves to the energy of the oscillating movement of the beam which is transmitted to the dampers, so that the energy causing the load to move in swinging motion can be absorbed by the dampers with a high degree of efficiency and the swinging movement of the load can be quickly stopped.Type: GrantFiled: December 30, 1976Date of Patent: July 30, 1985Assignee: Hitachi, Ltd.Inventors: Masao Higuchi, Shuzo Uno, Yasuhisa Ishii, Kazuhiro Makino, Kenichi Okasaka
