Camera pedestal

摘要

A camera pedestal has wheels that can be positively steered via a steering bar operating a corrective and crab mode steering system, and that may also be uncoupled from the steering system and operated in a caster wheel mode. The pedestal includes a base having a chassis and four leg assemblies. Each leg assembly has an upper component rotatably attached to the chassis, and wheels attached to a lower component via a caster fitting. The caster fitting allows the wheels to be positioned in a normal position where they are aligned with the rotation axis of the leg assembly, and into a caster position where the wheels are offset from the rotation axis, to allow for caster rolling movement.
