The KSI Safety Roller Crash Barrier is a highly visual deterrent for motorists, however it’s the technology ingrained in the design and construction of this crash barrier that has seen it awarded the world’s first MASH TL4 accreditation judged on:
- Structural Adequacy
- Occupant Risk
- Vehicle Trajectory Post Impact
KSI Safety Roller Crash Barriers are flame retardant and recyclable. Adding or removing rollers can adjust the barrier for complete suitability to any landscape. Solar powered lights and speed displays can be added when they are warrented.
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.
- Shock absorbing system
- Converts shock energy to rotational energy
- Decreases speed impact
- Redirects vehicles back into its lane
- Prevents driver and passenger fatalities
- Flame retardant and easy to install
- Visually stands out to alert drivers
The superior performance has been achieved because of its advanced design elements:
- Roller absorbs initial collision shock, which converts to rotational energy
- 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
Meeting global compliance
In addition to having attained the world’s first MASH TL4 accreditation, KSI Global Australia has achieved a portfolio of international accreditations, including: EN 1317, NCHRP 350, Austroads, Korean SB 4/5 and Federal Highways Administration (USA) approvals.
Proudly, our Safety Roller Crash Barrier is the first barrier in the world that has been tested for length of need and transition under MASH standard and achieved TL4-10, TL4-11 and TL4-12 with outstanding test results.
Our Safety Roller Crash Barrier, defined as a “semi rigid” safety barrier, demonstrated extremely high performance scores under MASH test conditions, in three key rating areas:
- Structural Adequacy – the ability for the barrier to remain functional post a crash impact. This is a critical when considering the time to repair barriers after a crash event
- Occupant Risk – the ability to minimise impact injury to vehicle occupants
- Vehicle Trajectory Post Impact – the ability to keep a vehicle’s movement directed in the direction of original travel. The key being assessed is the redirection angle to minimise or eliminate the likelihood of an errant vehicle being driven into oncoming traffic lanes, or into pedestrians on the roadside, property or furniture
- TL4-10: 1,100kg vehicle at 100km/h at 25-degree impact angle
- TL4-11: 2,270kg vehicle at 100km/h at 25-degree impact angle
- TL4-12: 10,000kg truck at 90km/h at 15-degree impact angle
- Designed for length need and transition
- ‘Safety Roller’ is recyclable, eco-friendly and flame retarded
