Using The Quattro Sl Pedestal Height Adjustment; Steering - Vinten Quattro SL Operating Instructions Manual

Using the Quattro SL pedestal
Height adjustment
The column (5) has an on-shot stroke of 100 cm (39.4 in.) and the load can be moved over this distance,
in perfect balance, by raising and lowering the steering ring (4). The movement is adjustable for drag (17)
and an on-shot clamp (6) can be used to hold the moving column in position if fixed height operation is
required. A markable height indication scale is provided on the second stage of the column. Operators can
use this scale to record working heights to be returned to whilst shooting.
WARNING!
Drag control
Column movement is adjustable for drag and this is set according to operator preference by means of the
drag control (17) located at the base of the moving column. Turn the control clockwise to increase the drag
setting, and counter- clockwise to decease it.
On-shot clamp
An on-shot clamp (6), located at the base of the moving column, can be used to hold the column in position
if fixed height operation is required. Move the clamp lever fully to the left to apply the clamp. Move it fully
to the right to release the clamp.

Steering

Directional control of the pedestal is achieved by turning the steering ring (4) mounted at the top of the
column. The steering system is geared so that the wheels turn by the same amount as the steering ring.
This ensures, for example, that with the pedestal set to crab, turning the steering ring by 90° will also cause
the pedestal to change direction by 90°. The steering ring is fitted with indicators which, when aligned with
the crab/steer pedal (15), indicate the straight-ahead position and thus provide a reference point when
steering.
Position indicators (12) in the centre of each vertical face of the base allow the camera operator to
accurately position the pedestal.
The pedestal has a crab/steer arrangement with a foot-operated changeover mechanism, which provides
a steer setting - one wheel steering, two fixed; or a crab setting - all three wheels turning together. Pushing
the pedal (15) operates the changeover mechanism which toggles the pedestal between crab and steer.
Although the button can be pressed with the wheels in any position, the changeover will not occur until the
wheels are all facing forward, so the steering ring may have to be turned by up to 180° before the
changeover mechanism engages. This arrangement ensures that the fixed wheels will always lock in the
straight-ahead position when changing from crab to steer.
Steering rings of two diameters and with either type of steering indicator may be fitted (See Changing the
steering ring on page 19).

To ensure maximum stability, particularly when moving over uneven
surfaces, reduce pedestal height to a minimum.
Take care not to trap fingers under the steering hub or between column
elements while pedestal height is being reduced.
