ABSTRACT:
A mobile base for supporting a camera crane arm includes a chassis having front and rear pairs of wheels. Front and rear steering angle compensators are linked respectively to the front and rear wheel pairs. The compensators are pivotally mounted to the chassis. Ground wheels and bogey track wheels are mounted on a kingpin/axle housing at each corner of the mobile base. Kingpins threaded into the kingpins/axle housings act as jacking posts. The mobile base may be steered by one or two operators in various steering modes.
