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
