ABSTRACT:
An improved hydraulic valve for a camera dolly includes Teflon inserts around a valve pin to reduce vibration and noise. The ratio of movement between the boom control, which controls the up and down movement of the arm on the camera dolly, and opening and closing of the hydraulic valve, is increased to reduce the sensitivity of the valve to boom control movement. The boom control includes ready up and ready down detents which provide the user a tactile indication of where to position the boom control for immediate up or down movement.
