The elevated platform is triangular, and the tripod supporting the TV camera is placed thereon, and releasably locked. The elevated platform is of less area than the lower platform, exposing a portion of the latter, and an adjustable operator's seat is mounted on the frame, over the exposed position of the lower platform. Wheels are provided, non-castering at a rear end of the cart, and casters at the front end, and a brake at the front end between the casters actuatable by the foot and when in braking position, lifting the front end of the cart off the floor.
