| CLARK MASTS LIGHTER, SIMPLER AND LOWER COST FIELD MOUNTED PORTABLE MAST KIT - UP TO 16 METRES | ||||||||
 |
The Clark Masts 73-S Field Mounted Portable Mast System uses the same tubular mast section and erection stand as the Type 73. However, because it is intended for lighter loads and a maximum mast height of 16 metres, some major units of the 73 system have been simplified. Guys are Kevlar in place of steel and are safely controlled by hand with a centrally mounted winching device. The mast lifting hoist is much lighter but still master of the work. The result is a lighter, faster, lower cost military portable mast system whose common inventory of components fits very well in the logistics of existing Type 73 portable mast kit users. |

| The Clark Masts TYPE
73-S portable military field mounted mast kit, as with the TYPE 73, is built around a specially
drawn an machined aluminium alloy tube 101.6 mm (4")
diameter by 1.22 metres effective length. These tubes
plug into one another with a generous overlap and are
rotationally locked by a pin and slot arrangement. This
system works effectively even in muddy and dusty
conditions. The erection gear consists of a guide box
which is supported on 3 splayed legs fitted with large
area detachable feet. Detachable steps are also fitted to
the legs to allow the operator to fit the portable mast's
headload. Mast sections are introduced into the guide box
from underneath and are lifted by a simple lift and
pulley block. When fully raised, each poratble mast section is
secured by a cross pin, the pulley block lowered and the
process repeated for the next section. Clark Masts Type 73-S portable masts are guyed at each 8 metre level either by Kevlar guys controlled individually through a simple hand unit or steel guys using a leg mounted guy winch from the standard TYPE 73 portable mast system as an option. A variety of headload attachments are available for the Clark Masts Type 73-S portable mast kit including a mechanically operated rotator head for allowing 2 antennas to be supported and individually directed. All equipment for the Clark Masts Type 73-S portable field mast kit is carried in hand held bags. The heaviest packed bag, at 32 Kg, being that which houses the kit's set of legs . All materials and finishes are of the best military standards of quality. Only materials proved to be long-life and totally reliable in a military environment are used in the Type 73-S field mountable portable mast kit. |
