WHY CHOOSE DEFENDER BARRIER®’S POSITIVE PROTECTION?
Defender Barrier® offers that positive protection and is accepted for use on New Zealand roads by NZTA.
Defender Barrier® by Safe Barriers is designed and tested to offer the highest level
of positive protection to road workers and the travelling public.
Defender Barrier® offers impressive safety at 30 kph on a winding coast road or 100 kph on a motorway.
It is the only barrier in New Zealand today that can be used for road construction
safety as a free-standing system allowing rapid deployment without water, and a
low-deflection anchored system on motorways and tight work zones.
DEFENDER BARRIER® BETTER BY DESIGN
Unlike the old 12 metre steel barriers that were first tested and approved under the superseded NCHRP 350 test standard, Defender is designed and tested from the ground up to be fully compliant with the new and more robust MASH16 standard. They are designed and tested to cope with up to 59% more energy from an impact than the older products, making your site safer from impacts by larger vehicles on the roads today. This means that Defender is shorter with a tighter connection to ensure that it can absorb energy and prevent vehicles getting into the work area. But don’t let the 3.9m length fool you. With Safe Lifter, it is just as quick as the old 12m barriers to install.
QUICK & EASY TO INSTALL
NO MORE PLASTICS
DEFENDER BARRIER® DIRECTLY REPLACES WATERFILLED SAFETY BARRIERS AND CONCRETE SAFETY BARRIERS.
SWITCH TO STEEL
USE DEFENDER BARRIER® FREESTANDING
AND SAVE THOUSANDS OF LITRES OF WATER
Low speed works are often protected by waterfilled plastic barriers because they are the familiar default barrier, the one that the hire company send. Plastic waterfilled barriers have now been superseded by Defender Barrier® Freestanding.
Freestanding Defender Barrier® uses removeable ballast boxes to provide the mass you would normally get from water. This means that a 150-metre work zone using Defender will be ready in a little over an hour compared to 9 hours of water filling before the plastic barrier site is ready.
The great advantage of Freestanding Defender Barrier® is that in testing it moved only 1.2 m at 70kph. The most popular waterfilled barrier moved 4.1 m in the same test.
Clearly, when you switch to steel with Defender on your job site you save thousands of litres of water and the site is a safer site for the workers.
MAKE YOUR WORK SITE SAFER
Safe Barriers has collaborated with leading contractors and traffic management planners in New Zealand to help make the work sites safer.
Companies such as Parallaxx Temporary Traffic Management regularly collaborate with Safe Barriers and contractors on ways to make sites safer with Defender Barrier.
See below some works that have been done by Safe Barriers.
Safe Barriers supported Parallaxx designers with technical assistance to design a barrier layout to ensure safe work zones during the works.READ MORE
DAIRY FLAT HIGHWAY – AUCKLAND
When it comes to the more regular urban use of barriers, companies such as Dempsey Wood have a stock of Defender that they use regularly on their road projects.READ MORE
SOUTHERN MOTOR HIGHWAY – AUCKLAND
CPB Contractors undertook the widening of the Southern Motorway in Auckland between Papakura and Takanini that has recently been completed.READ MORE
WAIHI TO OMOKOROA – SH2
Our friends at HEB have also chosen to keep a stock of Defender Barriers and have selected them for use on the Waihi to Omokoroa upgrade (SH2) to ensure the safety of workers on this vital road upgrade.READ MORE
KAIKOURA – NORTH CANTERBURY
One of the more interesting uses of Defender
Barriers is at Kaikoura. After the devastating
earthquakes coastal roads had to be rebuilt.
COMMITTED TO SAFETY
Safe Barriers has been committed to safety on New Zealand roads since the introduction of Defender Barrier. Our team turn up to sites to assist and provide training and technical support as required. We work closely with NZTA, Contactors, hire company and leading traffic planners to ensure that Defender Barrier is used the right way in the right place to offer the greatest possible safety to workers and drivers on New Zealand Roads.
Companies such as Parallaxx Temporary Traffic Management regularly collaborate with Safe barriers and contractors on ways to make sites safer with Defender Barrier.
Recently, works on the Mangawhai Bridge by Freyssinet were required. Safe Barriers supported Parallaxx designers with technical assistance to design a barrier layout to ensure safe work zones during the works. David Moule and Russell Hood of Safe Barriers visited the site to examine the installation and provide certainty to the client that the system had been installed correctly.
Dairy Flat Highway – Auckland
When it comes to the more regular urban use of barriers, companies such as Dempsey Wood have a stock of Defender that they use regularly on their road projects. Again, with the design assistance of Parallaxx and the technical expertise of the team at Safe Barriers they have used Defender in a multitude of locations. One of the highest profiles of these is the upgrade they carried out on the Dairy Flat Highway at the Coatesville Riverhead Highway intersection to the north of Auckland.
On this site Dempsey wood used our anchored Defender Barrier® system and the Defender Hinge to ensure positive protection on the tightest corners. The Hinge allow for radius turns of 0 – 90 degrees. Unlike the older barrier types that cannot make these turns and requiring the dangerous butting of two ends together.
Southern Motor Highway – Auckland
CPB Contractors undertook the widening of the Southern Motorway in Auckland between Papakura and Takanini that has recently been completed. Safe Barriers worked with the team at CPB and supplied Defender Barrier to be installed as a low deflection system in the 80 kph Motorway work zone. This installation was a typical high speed installation with system lengths of up to 600 m in some cases. In fact, the CPB site had an exclusion zone of 1.2 m for workers on this roadworks which meant that in an emergency they could have used Free Standing Defender Barrier and still been able to maintain the same exclusion zone.
This is the advantage of a barrier tested in multiple deployment forms. Deployment options open for the contractor that are not there with the old 12 m steel, concrete safety barriers or plastic waterfilled barriers.
This stock has now been moved to another CPB site at Tauranga. This Defender barrier is the same barrier that was used on the Mangawhai Bridge and by Dempsey Wood.
One of the more interesting uses of Defender Barriers is at Kaikoura. After the devastating earthquakes coastal roads had to be rebuilt. Our hire partner Kennards worked with NCTR to provide safety for motorists and workers with technical support and site visits by Safe Barriers. The sites were tight, and unsuitable for plastic waterfilled. Defender offered a solution that NCTR and Kennards Christchurch could work with.
Waihi to Omokoroa
Centred on the HEB site at Katikati, this projects involves the periodic widening of SH2. The existing two lane road is being upgraded to improve safety. There are multiple sites, that will require multiple barrier moves and a very narrow carriage way that carries a substantial volume of traffic between Auckland and the Bay of Plenty. HEB construction sort advice from Safe Barriers on performance of Defender Barrier as they were looking for a system that could offer the lowest possible deflection in the conditions to maximise safety of the work force. David Moule from Safe Barriers visited the site and then again after HEB chose to use DEFENDER to ensure full training and proper use of the system.
