A crane for lifting, moving, and positioning a camera or other object. The Omni-Boom crane configuration allows much more unrestricted movement that a conventional single boom design. The single boom design uses one vertical axis for azimuth pivoting movement, and one horizontal axis for up and down elevation movement. The Omni-Boom has two upright axes perpendicular to the main boom, one for a distal camera boom, and one for a proximal counterweight boom. These extra upright axes allow more horizontal freedom while maintaining the balance of the crane. Throughout this increased range of motion, the support of the camera remains level. The support can also maintain a constant camera aim azimuth rotational relationship with the base of the crane. If the base is stationary, the camera support is always aimed in the same direction, on the horizontal plane, if desired. Having rotational consistency, combined with greater freedom of horizontal motion, this crane offers unique possibilities for camera movement and control.
