PT & YT
SERIES

PT,
THE ORIGINAL TELESCOPIC CLARK MAST
|
|
The PT Series were the very first
air operated Clark Masts to be developed and now
form part of Clark's Phase 2 Series
|
|
.
The early masts featured heavy aluminium
alloy construction, anodised for corrosion resistance, keyed tube
sections enabling the mast to be turned, adjustable bearing
surfaces for long life and a coned ring system for rigidity when
fully extended. Today's masts still carry these features plus
torsional locking and other improvements. Like all Clark
air-operated masts, extension is by low pressure air, maximum
pressure 1.8 kg/cm3. From their introduction in the 1950's the
original PT masts were immediately attractive to organisations
involved in television field strength measurement and
radio/television news reporting vehicles. Today, they are still
the first choice for these applications. Clark have a wide range
of Mounting, Guying and Air Accessories available for the PT mast series,
including Vehicle Roof Mounting Trolleys and field mounting
Tripods.

YT
SERIES, THE PT'S BIG BROTHER
The YT Series is a development of the PT,
however it features a 127 mm (5") diameter base tube which
increases the weight and height capacity. In other respects it is
essentially the same as the four models in the PT range which
also have 127 mm base sections. Both the PT and YT form part of
Clark's Phase 2 series and are available with plain guide collars for low
retracted height or locking (combined) collars used for long
periods extended without a continous air supply. There is also a
very full range of accessories available for easy installation in
a wide variety of vehicles. In addition the masts may be field
mounted and guyed using Clark Accessories.
