Real men put chains at -20°C in snow and rain alone in dark.

Seems safe...

thats bad damn it
Caper77
We have these on our fire trucks. We call them onspots.
ChefJameBalls
That's the/a brand name, I've installed them on fire trucks
Medic75
We have this setup on one of our fire engines. I've always been curious how they worked.
CramSandwichandaNukaCola
Helps acceleration on slippy roads. Now, steering and stopping at your increased speed.....
gaggmaggot
they have been around for years..they suck...called "on spots"
Cutthroatlemur
Brilliant!
mardonious
ok...but why just not use tire chains? like everyone else
CallMeSleeper
Swedish technology I suppose (judging by the registration plates on the trucks)

Works. We have them on all of our fire trucks.
Mithraparty
The county ambulances here in North Georgia have em as well.
outlanderengine
These have been around for a long time. School buses in my area back in the 90's had them. Not that great for unplowed, deep snow.
TheNonInsestuousJaime
Just gotta watch out for your dalmatians...
Flavonoidz
This is one of those very good very bad ideas.
zoilz
Actually not. This is AMAZING. Using those daily on our trucks here in Norway. Have saved me more times than i can remember. But like 1/2
Flavonoidz
I can see accidents happening with fast spinning chains under a vehicle, either hitting pedestrians or other vehicles, chains snap.
Guerilja
They spin off the wheel. So: tires dont spin, chains wont spin.
zoilz
2/2 People say it's only good for situations where the chain is needed right away, while you're driving for example.
zancite
We use these on the ambulances, they work great.
quixotegut
The noise...
Guerilja
On snow... Not much.
quixotegut
Something about that apparatus looks like it's also hitting the sway bar, though.
NorthWestOutdoorsman
Even compared against normal chains that has to be insanely loud. Cool idea though
Slattefors
Sweden, yay!
n0n53n53
These are on school buses all around the Portland OR area
prodmerc
Yeah... that USA logo tho -_-
youtah
We do this for several of our buses here in Utah.

Awesome, but what happens if you hit a pothole?
atrevelyan
If the chains are deployed for that much snow, potholes don’t exist. Either do speed bumps.

You can't see, or feel them as there is to much snow.
griffinsage808
i hit potholes in the winter. they actually get pretty bad in some places.

This. Especially on roads that aren't paved, the potholes get worse. Plus they're harder to see

He needs to set that up first, he is far behind in getting a rep. Take advantage now before he is shut off from us commoners.
MechKelly
Ambulances and other emergency vehicles use these a lot. Makes response times much faster when you don't have to stop and put on chains.
Bobacrow79
Michigan here. Get this shit in the Lansing market NOW! Particularly just outside the city.

On-Spot chain system.
FarmerFerg
As a volunteer firefighter, fuck those useless annoying bastards. I’ll gladly spend the 20 minutes to put conventional chains on instead.
Vaenaemoenen
Time is money! Ain't nobody got time for stopping&chaining!
IjustsaywhatIthink
I disagree, we lift the chains for fast travel on the cleared streets and drop them on the icy side roads for traction. They work very well.

Chains can break from fatigue. Hate to be the car behind them
valkrez
I love it when people point out problems I didn’t even consider.
Cyrano517
That was my exact thought.
Thalarctos
They're not really moving all that fast, and aren't usually needed at higher speeds anyway. This is mostly to get past hills/stops.
ecchanQueen
Speed limit for them varies; either 30 or 50 kph.
AbsolutelyNotTheNSA
In those conditions you really shouldn't be that close to a truck for it to matter, and neither vehicles should be going too fast.
ShepherdsPieismyfavorite
This is what I was here to state. Thank you!
LSAH
Realistically, a broken link can be thrown some distance. There is chance to hit anything at the sides, from cars to people to buildings
McDsHotMustard
and monkeys might fly out of my butt.
MeanHug
Probably no different that regular chains for tires?
iConfirmAnythingAndEverything
Doubt these would be used for long hauls, basically to help with especially slippery spots. on top of the fact most places have banned 1/2
iConfirmAnythingAndEverything
them from major highways or populated areas. I'm speaking as far as Canada goes, not sure about Europe like this is shot.
NePb
The way Canadian roads get plowed (By traffic, not snow plows), these chain mechanisms would be compromised very quickly.
ThermoNuke
Not if you let them have a nap
SherMattLockSmith
I think these are meant for low speed only, I couldn't imagine these being used over 30-35mph.
lagavulin16
Are regular chains legal over 35mph?
SherMattLockSmith
A quick googling doesn't pull up any actual laws, but manufacturers each have their own top speed, from 25-40mph.
MacClay
The ones we used were only rated for 20mph. It's a 'gets you started', not a 'fun on the highway' thing.
pc404
Redbull can fix this
idonthaveanyideawhatthehelliamtalkingabout
yeah that happens with regular chains also.
KrilatiVoin
the car behind them won't be moving though. miss me with this material mechanics sh*t.
BatmansUnderPantsAreSoSoft
I don't think this is meant to be turned on ALL the time. Just in areas where you need it for that moment.
ThePastmaster
I'd hate to drive OVER anything like a rabbit or a hedgehog.
MonsieuRoberts
Bruh you think there's traffic jams in Nunavut trucking trails? Doubtful.
TheRandomLibrarian
Cars break from fatigue too. We still drive around behind them all the time. :D
jaono
I have a bigger worry about the mechanism they spin on. Great for groomed roads not real winter conditions.
ziccu
those things will also shoot any kind of small but hard objects really hard in the face of some one, possibly an innocent bystander
Wolverenis
You can only go maybe 20 mph with chains like that. Definitely not highway speeds
dagg3r
Running a cable through the links should prevent this.
Memaleph
Probably not intended to be used at full speed on the highway.
Fastcart4
The max speed on these is 35mph, we use them to get back to the station if it gets bad while we are out. Then we install real chains.
wildmansam
Do you really think they engineered this entire, elaborate system and put no thought into the fatigue rating of the chains being used?
Leithoa
Yes. But even though they do have some maintenance cycle calculated, how many cheap-asses are going to ignore it?
KuldFyt
You really think an engineer would do that? Just build something cool without considering the safety ramifications?
ashackatak
Trucks use tire chains all the time, and they do break. At least this would make them easier to inspect and change
borazhasleftthebuilding
20yrs, ive broken one chain, one cross chain to be exact.
idonthaveanyideawhatthehelliamtalkingabout
6 years, i have broken 4 and threw few away because they where bad, but i use the a whole lot over wintertime in Iceland
borazhasleftthebuilding
i use em mostly for mud, https://imgur.c">/MaCTZIm">https://imgur.com/MaCTZIm /undQN6r
borazhasleftthebuilding
every tire chained...all 3 drives and both steers https://imgur.com/3kMqG3S
IvanReznov
Ok but on the same thought, whats the difference between that and tire chains?
24Volts
Snow chains are a pain and a half to strap on to the wheels.
24Volts
And taking them off because you want to go faster than 20 mph is also no fun. Kneeling in snow trying to rip off ice glazed chains sucks.
Djchoragos
I think just temporary and self deployable
Djchoragos
Oh I see your point. Sorry. Maybe because these spin scarily fast?
ThailandExpress

T3HB1GC4T
Temporary/instantaneous deployment. Easier than taking them off/on repeatedly with terrain change.
IvanReznov
I was talking about the deterioration and them flying off bruh. I understand what it is, I'm talking about the dangers they implied.
NapoleonDynOmite
Have you ever had to stop and put chains on in the cold/wet/snow? Not fun or easy
IvanReznov
"That" was talking about the break from fatigue, not the chains themselves dudes...
intashu
I would hope and assume these are for vehicles in remote locations only. Because that's my thought too... Flying chunks of chain... Ouch!
Asianbomber13
They use chains on The mountain highways of California
Leithoa
Not that remote. Plenty of sections of highway require chains. Lots of states allow them October-April, some restrict it to bad conditions.
Leithoa
If you have your chains on, you're not going posted highway speeds. Probably under 45. Not that that removes all risk from flinging them.
makeSX
Normal stuff for all trucks in northern Europe, no accidents what-so-ever
intashu
I'm sure they're well maintained and regulated then? I can just see a broken link flying through a windshield otherwise.
idonthaveanyideawhatthehelliamtalkingabout
Well they have happen, i watch one chain flew from under a truck and into a car, there was just no one in that car.
makeSX
well of course accident _always_ happen, but not in the amounts that people were commenting here "death flies in your face on the road 24/7"
idonthaveanyideawhatthehelliamtalkingabout
ohh no, i have been driving in Iceland for 6 years, first time i saw that happen and i have never lost one from under my truck
ItsNotASchoonerItsASailboat
It'll bounce around under the truck and get stuck in the snow. Plus if you're a trucker driving in that you'll probably maintain your chains
ANightAtTheCocksbury
nah. make something almost maintenance free and it'll never be maintained. make 'em put the chains on manually and they'll get checked.
ShowMeYourButtonhole
Chaintenance.
ASDusername
I guess you could always put up metal plates behind the wheels to stop that in a similar way to the rubber flaps stopping slush/water
amyhadalittlepond
Maintain your chains before somebody else takes yours out of your frame and puts your game to shame
Subjec
Cover up your face , you can't run the race, the pace is too fast , you just won't last!
ohapieceofcandy
I have a dent in my bumper from a hook that says otherwise
amyhadalittlepond
Quaft the hook, "otherwise".
ohapieceofcandy
Actually it's the dent that said it
ItsNotASchoonerItsASailboat
Not sure what a hook hitting your bumper has to to with snow chains coming loose
metzershmit
I wonder what the hook could be attached to? Maybe a tow truck. Possibly on a chain.
ItsNotASchoonerItsASailboat
Which has nothing to do with chains for snow tires that aren't dragging on asphalt... way to be a dick, though
iamthugnasty
I've once drove behind a trucker who had a chain hanging down onto the road and shooting sparks as it drove. When we stopped I told him.
iamthugnasty
He proceeded to cuss and yell at me for being rude. He didn't fix the chain.
AccidentalStalker
Were you rude?
iamthugnasty
No, just motioned for him to roll down the window and then told him it was dragging.
ItsNotASchoonerItsASailboat
Different situation here. These chains are just for the tires when there's snow on the ground.
iamthugnasty
Yea, I simply meant that they don't always maintain them. These would have very little use though so it wouldn't take much.
ImgursLibertarian
Make them steel, and design the stress for below half of yield, and you will never reach your fatigue limit. See:
bawsinmahmouth
You should give a copy of shigley's a gander... because that's not how things work. Like at all.
tiramigiu
there is a reason why chain flail attachments for weed whackers were outlawed...people getting killed by them flying off.
idonthaveanyideawhatthehelliamtalkingabout
yeah they still break, source, x semi driver in Iceland
plebianmaximus
Stainless steel, not stainfree. Steel corrodes. Fatigue limit is one thing, scratches, microcracks is something else.
DynamicWeight
As a an engineer, how are you going to simulate the stresses on the chain? It seems rather.... dynamic.
ImgursLibertarian
Find the worst case position. Assume asphalt instead of snow. assume 10 ^6 cycles.

Google 'Creep deformation'.
