Vinten Osprey Plus - Pressurizing the Pedestal

Installation
Pressurizing the pedestal
The pedestal may be pressurized using the built-in pump, by using a
Portable Pump or from an external pressure source.
Ascertain the payload to be tted to the pedestal (payload = pan and
tilt head, camera, lens and all ancillary equipment). Referring to the
graph below, mark the payload on the horizontal axis then strike a
vertical line from the load gure to the balance line. At the intersecting
point strike a horizontal line to the vertical axis and read o󰀨 the
required gas pressure.
!
WARNING! Do not pressurize the pedestal beyond the
maximum safe working pressure indicated by the leading
edge of the red sector on the gauge. The pedestal is tted
with a pressure relief valve as a safeguard against over-
pressurization. Do not attempt to adjust the pressure relief
valve. Remove the payload before pumping.
!
WARNING! This pedestal must be pressurized only with
clean, dry air or nitrogen. A pressure reducing valve must
be tted to the pressure line between the cylinder and the
outlet connection of the hose. The reducing valve must
be screwed into the gas cylinder outlet. The maximum
pressure on the outlet side of the reducing valve must not
exceed 11.7 bar (170 psi). Do not pressurize the pedestal
beyond the maximum safe working pressure indicated
by the leading edge of the red sector on the gauge.
The pedestal is tted with a pressure relief valve as a
safeguard against over-pressurization.
Do not attempt to adjust the pressure relief valve.
!
WARNING! A pressurized pedestal will rise rapidly when
safety catch is released. Do not release safety catch
when pedestal is pressurized and balancing load is not
installed. Always restrain the pedestal by hand pressure
on the steering ring when the safety catch is released.
!
WARNING! Bottom stage elevation is assisted by a gas
strut. The bottom stage will rise rapidly if released with
no payload tted. Do not lean over the pedestal when
releasing the safety catch and/or the bottom clamp.
!
WARNING! A pressurized pedestal will rise rapidly if the
control valve is set to WORK.
Do not move the control valve directly from PUMP to
WORK.

Method Advantages Disadvantages
Integrated Pump
(For units that have
this.)
• No accessory needed
• Less strokes than manual Pump
• Cannot pump with payload tted.
Gas Bottle
• Fast
• Can add gas with payload tted
• Not always available
• Recommended training needed for
working with compressed gas.
Manual Floor Pum
• Easy for topping up.
• Readily available
• Self pump not available for all peds.
• Physically demanding so not
recommended for payloads over 60kg.
• Some pumps cannot achieve max
pressure on some models.
