Vision blue pan and tilt head

*OUSPEVDUJPOBOEEFTDSJQUJPO
The Vision blue pan and tilt head has been designed to support and perfectly balance a range
of professional digital video cameras. The head embodies an adjustable spring counter
balancing mechanism, LF drag assemblies for pan and tilt motions and an adjustable camera
mounting plate with 1/4 in. screw and pin assembly. The placement of the pan and tilt brakes,
drag controls and counterbalance allows the operator to easily adjust the settings whilst
operating the camera.

The balance system is easily adjusted using the Perfect Balance knob (10) located on the rear
of the head. The head supports payloads weighing between 2.1 to 5.0 Kg (4.6–11 lb). Maximum
and minimum payloads that can be balanced and tilt ranges are dependent on the weight of the
camera, accessories and on the Centre of Gravity (C of G) height. The counterbalance chart
(Fig. 3) shows the range of load and C of G height that can be maintained in balance. The
shaded area of the chart corresponds to those load/C of G combinations that can be balanced
over the full tilt range. The areas to the right indicate the progressively reducing tilt range with
greater load and higher C of G. Where a load/C of G combination falls outside of the chart it will
be necessary to increase or decrease the weight or the C of G height—if possible—to enable
the head to balance the load.
