Abstract
A lightweight camera crane has an outer arm pivotally attached to a base. A trim weight tray is rigidly attached to a back end of the outer arm. A moving counterweight carriage is supported on carriage rollers on top of the outer arm. An inner arm is supported on arm rollers within the outer arm. A camera platform is pivotally attached to a front end of the inner arm for tilt axis movement. An electric leveling motor connected to the camera platform via a mechanical linkage keeps the camera platform level regardless of the tilt angle of the camera crane. An electric extension motor drives telescoping extension and retraction movement of the inner arm via chains, belts or cables connected to the counterweight carriage and the inner arm.
