ABSTRACT:
A wheel unit for a camera dolly includes first and second wheel assemblies each having a ground wheel and a track wheel attached to the ground wheel. The diameter of the track wheel is less than the diameter of the ground wheel. A king pin disposed in between the first and second wheel assemblies has first and second axles extending therefrom at a declined angle. The first and second wheel assemblies are rotatably attached to the first and second axles, such that the wheel unit may be interchangeably used on ground or track.
