Abstract
In a telescoping camera crane arm, a second section is telescopically extendible into and out of the first section. The second section divided into a front segment attached to a back segment by a connector, to allow the front segment to be removed from the back segment. An adapter is attachable to the front end of the first section. A camera support attachable to the adapter and to the front end of the front segment. To configure the crane for increased maximum payload, the front segment is removed from the back segment. The adapter is attached to the front end of the front section, and the camera support is attached to the adapter, so that the camera support is then supported directly by the first section. A spring balancing system compensates for out-of-balance forces associated with changes in the elevation angle of the crane arm.
