Abstract
A camera dolly has a steering compensator including offset shaft sections and drive members rotationally displaceable from each other. The steering compensator provides steering angle correction in conventional steering wherein the front wheels of the dolly remain fixed straight ahead and the rear wheels steer. A crab-conventional camera dolly steering shift mechanism uses shift plates and sprockets on a vertical axle to shift between crab and conventional steering modes. An electronic shifter, provided as an accessory, automatically shifts between crab and conventional steering modes. A rocker suspension for the wheels of the camera dolly reduces undesired movement of the dolly, and of a camera mounted on the dolly, when the dolly wheels encounter a bump or obstruction. A bogey wheel system improves the performance of the rocker suspension by offsetting the wheels of the dolly dual wheel sets.
