ABSTRACT:
A camera dolly has a track wheel system including a kingpin pivotally supported on a dolly chassis. A kingpin tube extends laterally from the kingpin. An axle is pivotally supported within the tube on pins. A track wheel around a bearing is supported on a bushing on the axle. A knob unit threaded into the axle may be turned into a locked position wherein the track wheel is supported as in a conventional axle. For use on curved track, the knob unit is released or backed out, allowing the track wheel to shift laterally, to accommodate moving on curved dolly track, and to allow the wheel to steer on the track at a proper steering angle, by pivoting on the pins.
