Payload Weight and C of G Height Adjustment

!
WARNING! For safe and reliable operation the head and all mounted equipment must be correctly balanced.
The chart below shows the range of load and C of G heights that can be maintained in balance. The area below the balance curve (to the left)
corresponds to load / C of G combinations that can be balanced over the full tilt range of the 1040. The area above the balance curve (to the right)
corresponds to load / C of G combinations that exceed the capacity of the head.

Approximate estimate for
C o G Height (dependant
on configuration).
60 70 80
@ 4" (100mm) <52 lb. (23.5 kg)
@ 5" (127mm) <45 lb. (20.4 kg)
27 32 36
@ 6" (152mm) <40 lb. (18.1 kg)
@ 8" (203mm) <33 lb. (14.9 kg)
Tip. The height of the C of G is
difficult to measure, especially with
accessories fitted. Accessories fitted
high above the camera will effectively
reduce the total payload that can be
balanced.
However, since accessories are fitted
both above and below the lens, a first
approximation can be the distance
from the bottom of the camera plate to
the centre of the lens.
