ABSTRACT:
A height adjustable load carrying platform (7) wheel mounted for steering or crabbing movement and comprising at least three concertainable lazy tongs lattices of struts (5) forming a 3 sided pyramid which can be raised and lowered manually or under power, and includes a counterbalance mechanism (67). The structure replaces a conventional pedestal support for a camera or the like (such as T.V. camera) and is capable of being extended up to normal pedestal height, but is also capable of contracting to a lower minimum height than that of a conventional pedestal. Three and four axis hinges are described to permit the articulation at the corners.
