Abstract
A camera pedestal has a cylinder with a tapering cross-section for providing a uniform counterbalancing force using a compressed gas. Telescoping column sections which make up a column assembly have inner relief channels and outer slots for hardened roller strips. A column drive system has a hydraulic actuator to remotely raise the column assembly, and to lock the column assembly into any selected position. The column assembly is eccentrically positioned on its base tank. The pedestal is engageable to a receptacle on a camera dolly with a telescoping steering drive tube interconnecting a steering assembly on the pedestal with a steering system in the dolly.
