- Since the design of SMA Crash Cushions provides a sliding guide below the absorbing panels, such a guide could collect sand rendering it virtually impossible to clean on a routine basis. Would this not lead to a build-up of sand inside the guide which could hamper the performance during a crash?
It is necessary to consider that the guide is opened on the front and rear side. Consequently if the sand does not fill the guide and it is not wet it could escape due the large force involved in the crash.
Moreover the Crash Cushion can be also supplied with an optional cover for the guide in order to avoid the accumulation of sand or debris inside it.
- Are the SMA devices delivered already mounted?
SMA devices will be delivered already mounted.
For the installation it is just required to fix it on the concrete basement saving in this way time and money to reassemble the system.
- Are you looking for distributors? If yes, where?
Industry AMS is currently looking for distributors worldwide.
For applications just send us an email with information about your company, you contact details and the territory you would like to become distributor for.
- At which kind of barrier you can connect SMA Crash Cushions?
SMA Systems can be connected to every kind of barriers. Industry A.M.S. provides specific studies for every kind of necessity or request.
- Can SMA Crash Cushion be installed at Toll Plazas?
Yes, SMA Crash Cushions can be installed at toll stations.
Look at the SMA 80/1 Wide page.
- Do you have any video of Crash Tests? If yes, where I can watch them?
You can watch all the Crash Test videos for Crash Cusions or End Terminals on the SMA website.
They are available in each product page.
Moreover, the SMA videos are also available on the Youtube channel.
- How are SMA Road Restraint Systems stocked?
Crash Cushions are stackable one on the top of the other up to a maximum of 3.
End terminals are stored in groups of 9 with a 3x3 disposition.
- How can you recover a SMA System after an impact?
Usually after a standard impact you only need to substitute the internal absorbing cells in order to recover the system.
- How do you install SMA Crash Cushions?
It is possible to carry out the installation according to three different ways:
- Installation A: concrete basement with bushes,
- Installation B: concrete basement with chemical anchors,
- Installation C: chemical anchors on the asphalt.
- How many units can be loaded for container ( 20' and 40')?
The unit quantity depends on the model of Crash Cushion choosen by the customer.
For example in a 20” container there is the possibility to load n. 6 SMA 100P Crash Cushions, while in a 40" it is possible to load 12.
- If the SMA Systems are used outdoor what happens when the unit is filled with snow, thinking about snow getting very hard by melting a bit and then turn into ice? Summarizing: If the snow gets hard as ice, will the energy absorbing effect be threatened?
The crash cushion can be also supplied with an optional cover in order to avoid the accumulation of ice or snow inside the cells.
- Is it possible to install 2 SMA Parallel Crash Cushions side by side in order to cover a wider area, like a wall in a road tunnel (walls in emergency niches). Or is it possible to manufacture wider models on exact measurements?
It is not possible to install 2 SMA Parallel Crash Cushions side by side in order to cover a wider area.
The solution for this kind of situation consists in the installation of a SMA Wide or SMA Semi Wide devices, which present a wider shape than the parallels.
- Is it possible to install SMA Crash Cushions in tunnels?
SMA Crash Cushions are perfectly suitable for the installation in tunnels for two main reasons:
1) the reduced length of the system make it possible to place it in places with reduced space of installation (e.g. tunnels)
2) the system is completely made of steel and therefore it is non-flammable and tunnel compatible according to the UNI EN ISO 13943/2004 (Fire Safety).
- What does the ASI Index stand for?
The index ASI is intended to give a measure of the severity of the motion for a person within a vehicle during an impact with a road restraint system.
In order to be homologated, the Crash Cushion must have respected the Impact Severity Level:
Impact Severity Level Index Value A ASI ≤ 1 B ASI ≤ 1,4
- Which normative covers the homologation of SMA Crash Cushions? Do you have CE certificate for SMA Crash Cushion?
SMA crash cushions have been tested according to the specifications of the European standard UNI EN 1317-3 in order to get the homologation for the whole FAMILY of Redirective crash cushion.
The CE certifications were obtained for the whole family by performing crash tests according to the Table 4 of EN 1317-3.
- Why the SMA devices are made of steel?
The steel absorbs better than other materials, i.e. the plastic, the vehicle kinetic energy during the crash.
The steel also allows shorter devices in order to fill less space on the road.
Steel is not not flammable and it can’t cause combustions.
During the impact, while material like the plastic fragments itself becoming new risk for occupants of vehicles and other vehicles by occupying the road, the steel don't release debris on the road.
The steel resist every temperatures and it's totally recyclable and not pollutant.
