2. The BarrierGuard 800
a new generation of state-of-the-art design
The BarrierGuard 800 heralds a new era in road safety
technology. This new generation of road safety barrier
- Australia’s only TL4 rated Temporary Steel Barrier -
offers state-of-the-art design features and levels of
safety previously thought impossible.
It is light weight and quick and easy to install, ensuring
a highly-economical package in terms of transport and
deployment. The BarrierGuard 800 can be used as a
permanent installation, or for short-duration
roadworks in distant locations, or where there are
roadworks requiring frequent moves.

6. Assembly
The BarrierGuard 800 is anchored at each end of the run.
Torsional rigidity and self weight keeps it in place together with the anchors
producing low deflection.
The 12 metre barrier is built as two 6 metre pieces bolted together in the
middle with a male and female quicklink at either end. A 6 metre version is also
available comprising two 3 metres pieces bolted together. In runs in excess of
500 metres an additional interim anchor should be used.
Intermediate anchors (dog bones) can be placed at 250 metre intervals.
The BarrierGuard 800 uses the quicklink connection system, a feature unique
to this product. The barrier quicklinks provide a highly rigid and enormously
strong linking system at the top and bottom of every barrier link.
Coupled with the rigid anchoring, the quicklinks make the barrier highly impact
and deflection resistant whilst providing just the right amount of flexibility in
the steel body of the barrier to provide necessary energy absorption for the
impacting motorist.
For achieving emergency access or opening of the barrier, a designed system
of part of the barrier can act as a gate with the barrier being swung open or
entirely removed on castor wheels.

7. Easy to assemble
These opening points can vary from 6 to 60 metres according to customer requirements.
Anchoring can occur with either 450mm driven pins, chemical anchored bolts, mechanical expanding anchor bolts
or large diameter long plug in poor foundations.
An access window in the face of every section of the barrier allows unbolting to be done on site, for the removal of
individual barriers or part barriers, in the event of an impact where you have long installed lengths.
A full height termination barrier is available, which has a built-in end plate at its base for anchoring to the road,
as well as provision to link with an inner anchor shoe assembly anchored to the road at the intermediate (bolted)
midway point of the end terminal section. This arrangement provides the unique double anchoring system which is
the foundation of the strength of the barrier.
The barriers can stack together in a variety of configurations for transport which, depending on permitted load
widths and height restrictions, can allow loads up to 18 barriers or 216 metres in length.
The barriers can also be inverted. The barriers are easily and safely deployed using a crane attached to the truck.
Alternatively, any crane can be used to unload on site and either cranes or forklift trucks can be used on site.
