ABSTRACT:
A braking system allows for smooth and accurate stopping of a camera dolly operating on tracks. A pair of caliper brake modules attached to the dolly frame are sized so that they fit over and at least partially surrounds the track. When the caliper brakes are activated, brake pads are moved towards the surrounded track squeezing it and providing a significant braking force. This permits the dolly to be smoothly brought to a stop with no possibility of the dolly wheel locking and skidding. The braking system can be temporarily attached to the dolly by a removable fastener system, or it can be permanently built into the dolly. A master hydraulic cylinder with a conveniently placed actuating lever is connected to the brake caliper modules by hydraulic lines so that slave hydraulic cylinders can apply the brakes in response to the actuating lever.
