  2. 2. The BarrierGuard 800a new generation of state-of-the-art designThe BarrierGuard 800 heralds a new era in road safetytechnology. This new generation of road safety barrier- Australia’s only TL4 rated Temporary Steel Barrier -offers state-of-the-art design features and levels ofsafety previously thought impossible.It is light weight and quick and easy to install, ensuringa highly-economical package in terms of transport anddeployment. The BarrierGuard 800 can be used as apermanent installation, or for short-durationroadworks in distant locations, or where there areroadworks requiring frequent moves.Safety Features Low Costof the BarrierGuard 800 Low Transport Cost - About 216 metres can be trans- ported per load.Crash Tested - At speeds from 50km/h to 110km/h Low Installation Cost - Fast installation or removal atAt angles from 15° to 45° up to 300m per hour results in very low costs.With vehicles from 900kg to 13,000kgHigh ContainmentWill contain a 13,000kg bus at 70km/h at 20°Will contain a 7,500kg truck at 50km/h at 45° Other features • The BarrierGuard 800 has been approved by all Low Deflection state governments.1,500kg Car, 20°, 110km/h (EN 1317 - N2) • The BarrierGuard 800 offers high containment and Approximately 1 metre deflection low deflection levels.

  6. 6. AssemblyThe BarrierGuard 800 is anchored at each end of the run.Torsional rigidity and self weight keeps it in place together with the anchorsproducing low deflection.The 12 metre barrier is built as two 6 metre pieces bolted together in themiddle with a male and female quicklink at either end. A 6 metre version is alsoavailable comprising two 3 metres pieces bolted together. In runs in excess of500 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 uniqueto this product. The barrier quicklinks provide a highly rigid and enormouslystrong linking system at the top and bottom of every barrier link.Coupled with the rigid anchoring, the quicklinks make the barrier highly impactand deflection resistant whilst providing just the right amount of flexibility inthe steel body of the barrier to provide necessary energy absorption for theimpacting motorist.For achieving emergency access or opening of the barrier, a designed systemof part of the barrier can act as a gate with the barrier being swung open orentirely removed on castor wheels.

  7. 7. Easy to assembleThese 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 boltsor 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 ofindividual 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 isthe foundation of the strength of the barrier.The barriers can stack together in a variety of configurations for transport which, depending on permitted loadwidths 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.Access Window 7
