Abstract
A camera crane for use in motion picture and television productions, has a mast on a wheeled chassis. A weight bucket on the chassis around the mast securely holds counterweights used to balance arm. The steering section of the mobile base can be pivoted into a low position, to allow the arm to swing around the mobile base, without interference. A leveling system on the mast levels the mast, regardless of the orientation of the chassis. Outriggers are provided as an accessory to help stabilize the mobile base. Stiffening tubes on the arm stiffen the arm and protect the arm core.
