Cobham Antenna Systems EXB lightweight composite telescopic
These lightweight composite telescopic masts are push button,
vehicle- mounted masts designed for rapid extension and operation
without guy ropes. They are designed to extend to heights up to 15
m (payload height at 16 m above ground when vehicle-mounted) with
maximum payloads of up to 130 kg. EXB-masts are made of
carbon and glass fibre.
The EXB lightweight composite telescopic masts are extended and
retracted utilizing hoisting belts driven by a winch. This is an
effective, well-proven technique which is more reliable under
severe operating conditions (especially sand and dust). EXB-masts
have a double-belt system - one belt is used for mast extension,
the second belt is used to provide positive retraction to assure
proper operation under adverse conditions of wind and slope.
EXB-masts are equipped with an automatic latch mechanism for
controlling the order in which tube sections extend. The winch is
operated by an electric Winch Power Unit (WPU) with remote control,
with WPU versions available for either AC or DC power supplies. A
manual hand crank is provided as a back-up for power failure.
EXB-masts can be painted in customer specific colours.
