Pedestrian Safety Barriers

Oracle's A-Safe pedestrian barrier

is the most innovative safety barrier system. So innovative in fact, that it effectively makes conventional steel barriers obsolete.

The secret of Oracle's A-Safe's success lies in the polymer-based material that all the products in the range are made from. Unlike steel, which simply dents or crumples when a vehicle hits it, an A-Safe barrier will spring back into shape, thanks to its built-in memory.

Naturally, this greatly reduces the need for damage repairs, both to the barrier and to the vehicle itself. It's a principle that the motor industry adopted long ago, which is why you'll only find plastic bumpers on cars these days.

Thanks to their modular construction, Oracle's A-Safe products are supremely adaptable and easily installed, with no screws or welding involved. The initial outlay is more than outweighed by long-term cost savings with reduced maintenance and replacement.

Oracle's A-Safe offers many other benefits. Their yellow and black colour scheme enables both pedestrians and drivers to see at a glance where they should and shouldn't be. The colours are solid too, so repainting is never required.

All our products are tested and certified to British Standards and meet the most stringent Health & Safety guidelines. What's more, they're fully recyclable, with a much lower carbon footprint than steel.

Oracle's A-Safe offers a comprehensive line-up of products including traffic and pedestrian barriers, car park barriers, bollards, rack end barriers, handrails and access gates. But A-Safe is far more than just a range of products. It's a full consultancy, advice and back-up service, developed to ensure that you have the right product for the right application.

SPECIFICATION

Testing of Oracle's A-Safe Barrier products for compliance, and/or test until destruction of product for limitations.

Pedestrian Barrier Flexible plastic barrier constructed from extruded profiles, designed for pedestrian segregation, used to direct or guide pedestrians in a required direction or to restrict pedestrian access.
Objective Test barrier post for safe working loads and design limits. The output of this is to establish the safe working and maximum impact forces imposed upon the barrier under dynamic loading conditions. Test pedestrian barrier, simulating various sized vehicle impacts at 7 mph (11km/h), 90° to the barrier.
Test Specimen 1 x PB post (110 x 110 x 1160mm) having a steel base plate. Test Equipment Pendulum impact tester (PIT), having a 200 - 486 kg pendulum, set to 45° for 7mph (11 km/h). Measuring instrumentation for deflection and impact force.
Calculations The impact force which the barrier must withstand is a combination of different variables. The formula used is that to calculate the impact force is the same as that used in BS3699 part 1 Loadings for buildings. In vehicular impacts deflection is assumed to be 100mm, as the vehicle itself will deform or deflect the impact force energy. The deflection of the PIT is 15mm as the pendulum is a rigid structure.
Results The PIT test results demonstrate that the pedestrian barrier achieved a Safe working impact load of 65.1 kN force. Upon impact within the achieved safe working load, the barrier post may deform, which may result in the post deflecting up to 300mm, then return to its near true position/state The pedestrian barrier achieved a maximum impact load of 158.4 kN force. Upon impacts above the safe working limit of up to the maximum load, the barrier post may deform, which may result in the post lifting up from the base plate and deflecting up to 300mm, the deformation is likely to be permanent and severe damage may occur to the post such as splitting of the post in the region where contact is made with top and bottom of steel base plate. The steel base plate may also buckle.
Conclusion The pedestrian barrier is capable of withstanding a safe working load of 65.1kN impact force and a maximum impact load of 158.4 kN. This demonstrates the potential usage of the barrier in environments where manually operated pallet trucks, electric powered pallet trucks are. It may also be used in areas where lager vehicles are present in a controlled environment, for pedestrian segregation. The actual impacts is a combination of vehicle speed, mass and deflection, therefore it may withstand light impacts from larger vehicles. The test was carried out with impacts at 90° to the test specimen, this is the most severe type of impact. Angular impacts do not impose such great impact forces, for example a 45° angular impact could reduce the impact force by up to 80%.
