Patent ID: 7607519

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 activation of the actuator is proportional to movement of the control member relative to the actuator, and 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 at least one track; wherein the dolly is placed upon a frame, the means for placing the at least one caliper brake module in mechanical communication with the dolly including means for removing the at least one caliper brake module from mechanical communication with the dolly and placing the at least one caliper braking module directly in mechanical communication with the frame on which the wheels of the dolly rest, the dolly being stationary relative to the frame when the frame is in use, wherein the frame includes wheels running on the tracks.
