Vector 430 pan and tilt head

Introduction and description

The Vector 430 pan and tilt head is designed for use by professional camera operators working
with full facility studio and OB cameras, supporting and balancing a camera system weighing up
to 43 kg (94.8 lb). The Vector 430 pan and tilt head embodies a unique and patented spring
counterbalancing mechanism, thin film (TF) drag assemblies for pan and tilt motions and an
adjustable camera mounting plate with an EFP quickfit adaptor for rapid and secure attachment
of the camera.

Perfect balance

The spring counterbalancing mechanism comprises six springs operating against cams
connected to the camera mounting platform. The balance mechanism is adjusted using the
Perfect balance knob (5) on the lower right-hand side of the head, which varies the mechanical
advantage between the cam and the springs. For ease of use the Perfect balance knob (5)
incorporates a fold-out handle (Fig. 3). Note that the Perfect balance knob can be used without
the fold-out handle.
CAUTION
Do not attempt to adjust the Perfect balance knob (5) below 0% or above
100% as damage could occur.

Maximum and minimum payloads that can be balanced are dependent on the weight of the
camera system, and on the center of gravity (C of G) height. The counterbalance chart (Fig. 4)
shows the range of payloads and C of G heights that can be maintained in balance. The shaded
area on the chart shows the payload/C of G combinations that can be maintained in balance.
Where a payload/C of G combination falls outside of those shaded areas it will be necessary to
