  • Levelling system for camera cranes
    Patent number: 4943019
    Abstract: A levelling system for a camera crane employs a tachometer directly coupled to a horizontal pivot of the crane. The output of this tachometer is used to control a motor which by means of a worm and worm gear controls the level of a camera remote head. A second tachometer is associated with the worm in order to provide a feedback signal to the servo-amplifier so as to maintain the motions of the boom about the pivot and the worm gear in synchronism.
