Fitting And Balancing The Load - Vinten Pro-Ped Operator's Manual

Turn on the pressure supply and slowly increase the pedestal pressure. If not already fully
extended, the top stage
is reached, indicated by the lower edge of the red sector on the gauge (3).
Disconnect the charging line, but do not refit the Schrader valve cap at this stage.
Install the camera mount and payload and balance the load as described below.

.Fitting and balancing the load

After pressurization of the pedestal, the camera mounting and payload can be fitted and balanced.
The Pro-Ped pedestal has the standard four-bolt mounting plate
ious Vinten camera mounts including pan and tilt heads, Quickfix and Mitchell adapters. The
mounting bolts are captive in the pedestal and the bolt heads are accessible from the underside
of the mounting plate. When the camera mount has been fitted, the bolts should be tightened se-
curely using a spanner of the correct size. A Vinten spanner, Part No. J551-001, is available for
this purpose.
When the camera mount has been secured proceed as follows:
Fit the payload to the fully-extended top stage of the pedestal, ensuring that all items such
as pan bars, prompters, lenses etc, are fitted. Attaching these items at a later stage may
upset the pedestal balance. Install three trim weights
Using the Schrader valve cap (23), carefully reduce the pressure in steps of 0.15- 0.20bar
(2-3psi) until the payload is correctly balanced. A correctly pressurized pedestal will bal-
ance its payload such that it may be moved to any position over the full on-shot stroke with
minimum effort and will maintain its position when the steering ring is released.
WARNING! The Schrader valve cap
Fine balance and temperature correction may be achieved by adding or removing trim
weights (8).
