27. Ancillary equipment
A number of additional devices are available which can be interfaced with the
SECTOR
traffic
barrier to increase security or otherwise enhance the installation.
SECTOR breakaway coupling
The
SECTOR
breakaway coupling is a handy
boom coupling that minimises damage to the
boom pole by causing it to swing away to the
side if struck by a vehicle. The breakaway
coupler incorporates a micro-switch which is
connected to the emergency stop input,
meaning that the
SECTOR
will be barred from
operating the moment that the micro-switch is
unclipped. This significantly reduces the chance
of further damage to the barrier.
TRAPEX
TRAPEX is a barrier fence that can be fitted to
the
SECTOR
barrier boom pole (3m and 4.5m
poles only) to facilitate pedestrian access
control. The fence consists of a series of
vertical poles which not only cover the area
beneath the boom pole but also extends past
the boom pole, meaning that the boom cannot
be skirted. A link arm assembly prevents the
boom from being pushed aside.
SECTOR jack-knife assembly
Some installations may require – due to a
particularly low ceiling or similar hindrance
which has diminished overhead space as a
consequence – that the boom pole bend at an
angle to allow for sufficient clearance when
raising. A jack-knife assembly can be fitted to
an existing boom pole which will allow the
boom bole to bend at an angle by means of a
metallic “knuckle”, and to become level again
when in the lowered position.
