Patent ID: 7926623

Claim:
A braking system for a camera dolly riding on a pair of tracks, comprising: at least one caliper brake module sliding over a portion of at least one of the tracks and brakingly gripping the at least one of the tracks when activated, wherein first and second wheels of the dolly each run on a respective one of the tracks; means for placing the at least one caliper brake module in mechanical communication with the dolly; an actuator operationally connected to a control member which control member can be manipulated by a member of a dolly crew, when the dolly has a crew, to cause activation of the actuator, wherein the actuator is repositionable on the dolly to relocate the control member; and means for transmitting activation from the actuator to the caliper brake module whereby the caliper brake module brakingly grips the track; wherein the two caliper brake modules are joined to a subassembly, wherein the means for placing the at least one caliper brake module in mechanical communication with the dolly further comprises means for placing the subassembly in mechanical communication with the dolly, thereby allowing both modules to be simultaneously placed in or removed from mechanical communication with the dolly.
