Abstract: The present invention relates to a movie equipment dolly with a chassis, a lifting arm coupled to the chassis, a hydraulic system for lifting the arm, a plurality of steerable wheels, a transmission for orienting the wheels into selected steering modes, a steering system, slip idlers for selectively disconnecting the wheels from the steering system and transmission, and a control handle that has steering, hydraulic system actuation and transmission steering mode selection operations on a common handle, so that the operator need not remove his or her hands from the control handle when performing any of the operations. The movie dolly also has a levelling head coupled to the lifting arm which allows simple, simultaneous orientation of the levelling head roll and pitch axes by manipulating a pair of adjusters.
