3. HANDLING & INSTALLATION
3.1. Handling
Prior to shipment, the four mounting studs are removed from the base flange of the
pan and tilt head. The head is then packed with the tilt platform in its mid-position
with the locking pin in place and such that the brake knobs are protected from
damage.
The brakes are left free to prevent shock loads being transmitted to the gearing
should the head be roughly handled during transit.
It is recommended that this procedure be adopted should it be necessary to de-rig
the head for shipment to a new site.
3.2. Installation
3.2.1. Mounting the Head
The type 435 Pan and Tilt Head may be mounted in either the upright or inverted
position on a suitable surface, ceiling plate, column or pedestal, having four equally
spaced 10.5mm diameter clearance holes on a 111 mm pitch circle diameter.
Fit the four mounting studs into the base flange of the Head. This can be done by
locking a pair of nuts onto each stud in turn and then tightening them fully with a
spanner. Studs must be fitted with their short threaded end screwed into the base
flange of the head.
NOTE
WHEN NOT USING THE STUDS SUPPLIED, ENSURE THAT SCREWS USED
WILL NOT BE LONGER THAN THE THICKNESS OF THE BASE. SEVERE
DAMAGE TO THE MAIN BEARING CAN OCCUR IF THIS INSTRUCTION IS NOT
FOLLOWED.
With the pan brake free, manually rotate the base flange to establish its mid-position,
indicated by matching the red dot on the pan base with the red dot on the head
casing and having set it there, lock the pan brake.
Offer up the Head to its mounting face and enter the studs into the clearance holes,
such that the camera will face in the desired direction at its mid-travel point. Fit the
four 3/8 nuts and lock-washers to the studs and fully tighten them.
3.2.2. Mounting the Camera
Where the camera / lens system is supplied with its own support plate, it may be
possible to attach this assembly directly to the tilt platform. However, it is likely that
an intermediate plate will be required, having tapped holes positioned so that the
centre of gravity of the system can be brought as near as practical into line with the
tilt axis, using the slots provided in the tilt platform.
It is recommended that the camera, lens and mounting plate be assembled as a unit
and the approximate longitudinal position of the Centre of Gravity established before
fitting to the Pan and Tilt Head. An attempt should also be made to estimate the
