Abstract
A camera dolly has a split chassis having front and rear sections connected by a journal. A hydraulic limiter dampens pivoting movement between the front and rear chassis sections. The limiter may be adjustable to provide variable dampening. Face plates on the front and rear chassis sections bear against each other in sliding engagement. The split chassis dolly or pedestal simulates 3-point suspension when the pedestal is at rest, when there is sufficient time for the front and rear sections to pivot with respect to each other and simulates 4-point suspension when the pedestal rolls on the floor as the intermittent forces acting to rotate the front end rear sections with respect to each other during rolling are resisted by hydraulic dampening.
