Installation
If the camera cradle stops
in a horizontal position
(camera pointing directly
forward), the balance is
correct.
Setting the Fore/Aft Balance
Ensure that the head and camera cradle are level before
balancing. The camera and payload should be fitted on the
cradle, so that the load is balanced. This can be achieved by
moving the camera forwards (Fore) or backwards (Aft) on the
cradle.
1. Engage the tilt lock. Loosen the bolts securing the camera to
the cradle just enough to be able to slide the camera and
payload backwards and forwards.
2. Hold and steady the camera cradle, then disengage the tilt
lock. Carefully release the camera cradle and observe how it
moves and where it stops.
If the camera cradle tilts forward
(points downwards), then the camera
must be moved towards the rear of
the head (aft).
CAUTION! Risk of damage to equipment. Be prepared
to prevent the camera and cradle from falling away
suddenly.
The FH-145/FHR-145 is designed to allow the camera and
payload to swing 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 aligns with the tilt-axis pivot point,
providing true balance.
When the head is correctly balanced, the robotic drives will
need a minimum amount of effort to move the head. A correctly
balanced head and payload can be set to any tilt position and
the head will maintain that position ‘hands off’.
