An impact attenuator, also known as a crash cushion and the crash attenuator is a device intended to reduce the damage to structures, vehicles, and motorists resulting from a motor vehicle collision. Impact attenuators are designed to absorb the colliding vehicle's kinetic energy.
Impact attenuators are usually placed in front of fixed structures near highways, such as gore points, crash barrier introductions, or overpass supports. Temporary versions may be used for road construction projects "Impact attenuators can be categorized by the method used to dissipate kinetic energy"
  1. Many early models used successive rows of sand- or water-filled barrels or modules. Momentum is transferred to the sand or water, reducing the speed of the impacting vehicle.
  2. Friction. Some attenuators work by forcing a steel cable or strap through an angled slot or tube, converting kinetic energy into heat.
  3. Back early 2000’s it was widely installed the Crash Cushion System at a few interchanges and intersections area along the highway and road manage by highway operator and road authority. The most common is using crushable materials which has been inserted within a few segments in the telescopic rails
  4.  This unit is designed by having a plastic barrier at the front which will initially absorb the impact prior to the telescopic roles will be taking part where the cushion than will absorb the impact crash in stages
  5. Within a year of experience while this type of crash cushion fix, this has given tremendous headache when its require to liable for a HUGE MAINTENANCE COST. Within the range of initial installation up to RM 200,000.00 per unit which latter continue with highly prone damage of cartridge rubber up to RM 10,000 per unit, this is relatively high and indeed has created a hassle in yearly operating expenses. It was easily observed the crashed cushion remains without replacement with few operational and financial limitation. The rubberized cartridge is prone to wear & tear by weather reaction and subject to vandalism activity as well. This situation will be creating a bad image to the public and the response of the highway and road operator will be questioned.
  6. Viewing this restriction to the Road/Highway Authority/operator, our experienced engineer undertaking an extensive study. We have developed a BEST OPTION in the engineering practiced by introducing our new line of product Millennium Crash Guard Attenuator System
The system consists of a few components and the installation works could be done very short period without compromising the safety aspect. The Millennium Crash Guard Attenuator System is developing according to the following:
  • NC-test level 3 of Standard NOM-037-SCT2-2012 or higher.
  • Able to ABSORB & REDIRECT the crash impact.
  • Resist impacts of vehicles with speeds up to 100 km/H. REUSABLE COMPONENTS meeting 80% once crashed
  • The system components can be made of metal and plastic. All metal components require hot dip galvanized finish. All plastic components treated against weathering, fire, rain, heat.
  • Consider proper join and / or adequacy of the system with devices and / or existing furniture in the islet to ensure the continuity of the system functions
There is very minimal ground anchoring, the largest selection of transitions and modular technology allow the Millennium Crash Guard Attenuator System to be used in multiple speed conditions. The absorb Crash Cushion is ideal for highway/road operator due to the ease of maintenance after an impact and quick and easy deployment
