Roadside Cable Barrier "Cheese Slicer" Truck Crash Test

[panhead1219]

Those "Barriers" suck.  ALWAYS use a Jersey barrier.

[barrierguru]

@panhead1219 Cable barrier costs about $8 to $10 per foot. Jersey barrier costs $80 to $200 per foot. You want your tasxes to go up? Every barrier has its own performance limits and plenty of people have died after collisions into concretre barriers.

[FoamPackingPeanuts]

Unfitting music much?

[RoyRu85]

These kind of barriers aren't being uses in the Netherlands and here the government is putting a steel plate under te common ones on place with higher risks for bikers.

iIf you Google for "motorvriendelijke vangrail" you see what it is.

[polarbare14]

Thing to remember for motorcycle riders: when you go off the road at 55 or 70 mph... You don't have that nice steel cage to protect you like the rest of us. So ANYTHING is a deadly barrier: guardcable, concrete barriers, culvert headwalls, and oncoming traffic. If you lay the bike down and slide into the grassed median do you honestly think you will just stop? You'll slide straight across and pop up onto the opposing lanes. Trees, signs, lightpoles, etc all pose the same hazards, yet we don

[TheEspiritin]

maybe ther aren´t many bike riders designing the barriers...

they seem to be just for cars.

[ArticMuse]

a crash somewhere in the us proved this barrier is not effective..the car went under the cable and cross incoming traffic..killing all in the car unfortunately.

[curator23]

@ArticMuse This isnt the same type of barrier. This type uses a twisted pair of cables braced against the posts. This createst a massivley stronger barrier structure than the standard straight through cable barrier types. It's a type of tensegrity structure (wiki it).

[barrierguru]

@ArticMuse Every type of barrier has plenty of failures to their credit. None are 100% effective, but if the systems are 90% effective, you shouldn't say that proves that they are ineffective.

whats with the porn music? ugg

[chueffer]

I can see how dangerous these cables are to bikes. The simple answer is to put a sheet of steel in the front of the cables and posts. Good idea?

[barrierguru]

@chueffer The problem with the sheet of metal idea is that the system tends to lean back when struck. A plate at the bottom then becomes a small ramp to help the errant vehicle get over the rail.

[chromiumtrioxide]

It is true that tests (in Germany) have indicated that these barriers are more dangerous to motorcyclists than are "Jersey barriers" or "Armco" barriers. However it is a myth that they are "cheese sliced" by the wire rope. In the tests, all the serious injuries were caused by the support stakes.

[marksquicklube]

corny ass music

[union1861]

Does anyone know of a motorcyclist who has been injured or killed by impacting the CABLES? As many have noted, a human body hitting any barrier is bad. When sliding or rolling on the ground, hitting the post at speed also produces severe injuries. But cable barriers typically have posts spaced at greater distances than steel beam barriers. Where does the "cheese slicer" idea come from?

[tye331]

my uncle died cause a cable barrier decapitated him and i hadto identify the body it was a traumatizingevent

[union1861]

I am very sorry to hear that. My condolences. I know you may not want to get into details of such a tragic event, but do you know what actually caused that fatal injury? Was it the posts supporting the cables or the cables themselves? Or did he go over the barrier and hit something else?

[tye331]

it was the handle bars. the wire cut them and part hit his neck and then the rest hit a tree

[csplendrig]

not much of a barrier if it can be driven through so easily, eh?

[jubjub2105]

the wire stays in place to stop cars falling down embankments etc. the posts are made to not stop the impact, just hold the wire.

[LBTennis]

Where was the crash. Looked more like a truck turning

[sweetseventeen2008]

lol

[whattheheck1000]

Cool crash, but I hate the music!

[cimmerianpraetor]

a test with empty truck? what is the meaning of it? just imagine the full load of 40 tons going into that kind of barrier and what happens is that the truck just goes throught it like nothing

[barrierguru]

@cimmerianpraetor Testing on barriers is done to standardized conditions Vehicles used in crash tests are weighted to meet certain specific weights. Cable guide rails do occasionally stop heavily loaded trucks. Barriers can't be designed to handle every vehicle on the highway. They have to aim for the middle ground of providing a forgiving redirection for the most common vehicles: small cars to vans and large pickups. While massive concrete can stop a truck,it can kill car owners.

[MaximusMission]

Saw one of these n work about 1 year ago and it definately saved me & my family from a massive crash. Car came through the trees straight towards us and hit this barrier. Made it as far as the emergency lane before being flung back away from me.

It was scary as but it would have been a head on at 100kph if that barrier hadn't been there.

[RetiredAFGuy]

On a motorcycle you arent going to walk away regardless of the barrier you hit - speed and no protection at all makes you a bag of meat flying into a fixed object, but yes these aircraft style barricades are bad even for smaller, lower cars as they tend to cut the roofs off the cars and occupants.

[BHT195]

Regarless of what barrier you hit you will be hurt, but chances of survival dramatically increase when not sliced in half by and inch think blunt wire. These barriers dont really seem like a good idea.

[RayAir1]

Hitting any barrier on a motorcycle is deadly. You shouldn't be on one of those silly things anyway on the highway! Fool!

[BHT195]

Please don't call me a fool. I don't ride a bike, let alone ride them on motorways. I agree that chances of chances of survival when crashing on a bike at speed are low, but surely being cut in half makes the situation worse? At least with impact the body remains in one piece.

[RayAir1]

If you're dead, you're dead.

[BHT195]

Well said

[21sparrow7]

But can you be less dead?

[barrierguru]

@BHT195 The cables are almost never the "cutters". Bikers who reach a barrier are usually on the bike and go over the rail, or they are sliding on the pavement and collide with a post. W-beam has more posts than cable.

Posts havemuch more of a "knife edge" than the round shape of a 3/4 inch cable. Cable is relatively free to move and is being struck at a shallow angle. In contrast, the edge on posts has almost no give when struck by a body. It is much more likely to cut up a body.

[08scionxd]

these barriers do not cut, or as the video is called cheese slice vehicles, sure there will be marks from the cables but it cannot cut through a vehicle. each cable is at 1500PSI and every 250 feet in the cable there is a tension holder which stop cheese slicing, by the time the cable would reach the point of cutting a vehicle, the tension holder fails purposly to give more slack into the cable. (i know because i do the design and inspection of these systems)

[bugio22]

No what i said was they will cut through motorcycle riders.

[qwertyfredqwertyfred]

try the m74 going to scotland full of these types of barriers i have seen cars and trucks hit these mostly sleepy drivers and i drive there every night delivering

[swedehorn]

They are still in use in Sweden and new roads are built with them too. The costs are much lower than with a normal type of barrier.

[rage1umr]

...and they've become all the rage here in central Missouri. Yee haw.

[lordloff]

That is a dangerous barrier indeed. They started with them in Sweden, but stopped when they saw what the motorcyclist became into after a crash. Banned in Norway aswell.

[motorbyclist]

here in New Zealand just a few months ago a motorcyclist was cut in half when flung into this sort of barrier... a few days later a truck on the same stretch of motorway went straight through, hit two oncoming cars and crashed into a tree... no wonder these are banned in most parts of europe
