Introduction
1 The Vision Pedestal (Fig 1.1) is a fully portable pneumatic camera mount with self contained pump. It is
suitable for use either outdoors or in a studio and is designed to accept the Vinten lightweight pan and tilt
heads.
2 The pedestal has a central telescopic column, part of which may be raised or lowered during operation.
This column is supported on a skid assembly which has castoring wheels. To facilitate transport, the
telescopic column and skid may be separated and the skid folded.
3 The pedestal is equipped with a pressure relief valve to prevent a build up of excessive pneumatic
pressure and with a safety latch to prevent accidental operation of the telescopic column. The pressure relief
valve operates at one of two predetermined levels depending on the version supplied, and automatically
resets at a predefined level below this.
Description
4 The pedestal consists of two main parts:
4.1 A skid assembly
4.2 A telescopic column
Skid assembly
5 The base of the skid assembly consists of a centre casting which accepts the outer tube (14) of the
telescopic column. Radiating from the centre casting of the skid assembly are three equispaced skid legs (9),
each fitted with a castor wheel (8) and brake (7) and a foot support moulding (11).
6 When in place, the outer tube is secured to the skid by a retaining clamp (10) and three leg ties (4)
which are secured to the foot supports by rubber straps (6). Two versions of the skid assembly are available.
The OB skid (3319-3B) has 125 mm (5 in.) castor wheels and brakes. The studio skid (3319-3C) has 100 mm
(4in.) castor wheels with brakes and cable guards (12) and spring-loaded track locking pins (13).
