Device crane, especially camera crane
The invention relates to a camera crane which comprises a crane jib ( 2 ) at the end of which a camera receiving platform ( 30 ) is pivotably mounted with dampening elements ( 34 ) interposed between. In this manner, the oscillations that are caused by a traction and control rope ( 9 ) expanding under the load of the camera can be dampened, thereby allowing a perfect operation of the camera.
1 - 3 . (canceled)
4 . Equipment crane, particularly camera crane, with a crane support ( 1 ) and a crane jib ( 2 ) articulated pivotably thereto at a first articulation point ( 3 ), at the end of which an equipment-receiving element ( 6 ) is articulated to a second articulation point ( 5 ), attached to which at a third articulation point ( 10 ), which is at a distance from the second articulation point ( 5 ), is a traction element ( 9 ) which is guided from there to the crane support ( 1 ) and there articulated to a fourth articulation point ( 11 ) characterized in that a motion damping equipment ( 34 , 35 ) is arranged in the swivel range of the equipment-receiving element ( 6 ) and in the area of the second articulation point ( 5 ) which is able to damp the swivel movement of the equipment-receiving element ( 6 ) around the second articulation point ( 5 ).
5 . Equipment crane according to claim 4 , wherein provided as a damping equipment are several damping elements ( 34 ) that may be selectively switched on or off ( 35 ).
6 . Equipment crane according to claim 4 , wherein connected to an axis ( 32 ), via which the equipment-receiving element ( 6 , 30 ) at the end of the crane jib ( 2 ) is mounted pivotably therein, are damping disks ( 34 ), each comprising an inner disk attached to the axis ( 32 ), which is arranged, with an interposed viscous fluid, pivotably in an outer disk, which may be locked on the jib side.
