Introduction
The Vector 700/700H pan and tilt head embodies a unique linkage counterbalancing mechanism,
thin film (TF) drag assemblies for pan and tilt motions and an adjustable camera mounting plate.
The balance system is easily adjusted by a knob (14) on the right-hand side of the head. The bal-
ance adjustment control compensates for differing platform load C of G heights by varying the me-
chanical advantage of a bell-crank in the counterbalance mechanism.
Both the pan and tilt mechanisms incorporate TF drag systems to ensure smooth movement of
the camera about these axes and are fitted with control knobs (9)(11) to adjust the drag setting.
The drag controls are mounted on the left-hand side of the head. The whip-pan facility is unaffect-
ed by the pan drag setting.
Friction brakes on each axis allow the head to be locked at any chosen position. The operating
levers for both brakes (4)(5) are fitted at the right-hand rear of the head. A tilt axis centre lock (15)
is provided on the right-hand side of the head to secure the platform in the horizontal position dur-
ing transport or load changing.
A level bubble (8) is fitted to the rear of the head and is provided with a time-delay illumination
unit, operated by a switch (7). The battery for the illumination unit is contained in the base.
Pan bar mounting points (18) are located at the rear of the head, on either side of the camera
mounting platform. A telescopic pan bar is supplied and is attached using a pan bar clamp (10),
with angular adjustment available on the mount serrations. A second pan bar may be fitted, and
fixed and short pan bars are available as optional extras.
The camera is attached to the head by means of a wedge adaptor (1).
