Anti Crash Road Safety Roller Barriers For Highway Guardrail
Roller EVA material with elastic characteristics is used as raw
material, which can slow down the lateral impact process of the
out-of-control vehicle.
Moreover, the rotating barrel can rotate around the column under a
certain impact, driving the out-of-control vehicle to return to the
correct driving direction.
Safety Roller Barrier
While externally the Safety Roller Crash Barrier is a highly visual
crash deterrent that alerts drivers, it’s the technology
behind its design and construction that has seen it awarded the
world’s first MASH TL4 accreditation judged on:
Structural Adequacy
Occupant Risk
Vehicle Trajectory Post Impact
The Safety Roller Crash Barrier is a barrier system ingeniously
engineered to prevent fatal injuries by firstly
absorbing shock energy and subsequently converting that shock
energy into rotational energy.
The key to its effectiveness is the energy from an impact being
absorbed and then deflected into the barrier and converted into
rotational energy along the barrier.
This key lifesaving feature has enabled the barrier to perform
exceptionally well in the stringent MASH testing, which
additionally delivers its ability to survive moderate impacts and
consequently require little or no repair or replacement.
The superior performance has been achieved because of its advanced
design elements:
·Roller absorbs initial collision shock, which converts to
rotational energy
Widespread flexibility.
Completely suitable for all weather conditions, the Safety Roller
Crash Barrier can be installed in the median between opposing
traffic flows,
on curved median strips, curved ramps, diverging points, curved
downhill corners, hillside locations, school zones and in danger
zones,
protection zones for posts, street lights and general
infrastructure within the road reserve.
Cost efficient lifecycle.
The cost of the Safety Roller Crash Barrier out performs
traditional crash barrier systems as it requires less frequent
repair,
replacement and maintenance. More significantly the Safety Roller
Crash Barrier provides reduced occupant risk of injury.
The cost benefit of the Safety Roller Crash Barrier makes it an
irrefutable crash barrier solution comparing it to other semi
ridged barrier systems. The roller barrier provides the lowest
Severity Index (SI) for vehicle passengers compared to traditional
crash barrier systems.
·Front rails absorb second shock
·Back rails absorb third shock
·Metal pipe inserted between the rails to strengthen the post
·Frictional rotating stopper boards installed to the top and bottom
of the rollers act as clutch plates to decrease speed
