ABSTRACT:
A camera crane includes an improved balancing system having a weight bar attached to the crane arm, and balance weights moveable along the weight bar. Substantially each balance weight can have upper rollers resting on the upper surface of the weight bar, to support the balance weight on the weight bar and allowing the balance weight to roll along the weight bar. A brake may be provided on the balance weights to lock the balance weight into a selected position on the weight bar. If used, the brake may have a moveable brake pad and a brake stop. The weight bar can be attached to the crane arm via mounting bars, and with the balance weights each including a slot to allow the balance weight to move over or past the mounting bars.
