2. Position the head in the adaptor, ensuring that it seats correctly in the recess and the
safety button is depressed.
3. Lock the head in the adaptor by pushing the lever fully inwards to the right, until the
red safety latch engages.
To dismount the head from a Quickfix adaptor, proceed as follows:
1. Push up the red safety latch and unlock the adaptor by pulling the lever fully outwards
and to the left.
2. Whilst preventing the head from suddenly falling away, safely remove the head from
the adaptor.
Mounting the camera and payload
Mounting the camera
The head is designed to allow the camera and payload to move about its own Centre of Gravity
(C of G), as opposed to balancing with the use of springs or cams. The camera and payload are
mounted onto the camera cradle so the resulting C of G height aligns with the tilt-axis pivot point,
providing true balance. Depending on the camera configuration, it may be necessary to use an
intermediate plate (part no. 3384-11) to raise the C of G height sufficiently to align with the tilt axis
(see Balancing the head and payload on page 23).
To fit the camera, proceed as follows:
1. Switch OFF power to the head [13].
2. Position the camera cradle [1] horizontally and engage the tilt lock [5] (for detailed
instructions see Locking the camera cradle on page 29).
3. Using an Allen key (5 mm) or hex bit, loosen the three screws securing the camera
cradle to the tilt drive [4]. Carefully lower the camera cradle to its lowest position and
then secure into position. Setting the camera cradle in this way will aid subsequent
balancing of the camera and payload.
4. Place the camera onto the camera cradle and secure into position from the underside
of the camera cradle through the mounting slots [1] using the fixing screws supplied
with the camera mounting plate.
WARNING!
DO NOT exceed the maximum payload weight of 55 kg (121 lb).
NOTE: An intermediate plate (part no. 3384-11) may be fitted under the camera mounting
plate to raise the camera C of G to align with the tilt axis (see Balancing the head
and payload on page 23).
