The innovative column design provides outstanding stability end jerk-free control with exceptional smoothness and precise movements. Accurate camera balance is achieved at full extension by simply activating the bleed valve, releasing excess air pressure. The column supports a maximum payload of 55 kg (121 lbs) at 180 psi and the safety valve is adjusted at maximum 250 psi.On the foldable dolly, six position track lock, foot operated brake on each of the 125mm twin wheels and cable guards provide smooth movements in any desired direction. The column is firmly secured to the dolly by a double clamp, easily engaged by two ergonomic locking levers. A set of 200mm PNEUMATIC TIRES with wheel brakes are available for OB use.
