How to Install Tire Chains on a Commercial Vehicle

In our previous video session we demonstrated how to affix tire chains on a light vehicle. The tire chains that
we affixed in our previous video where those up in front me here,
typically called singles or some people tend to call them
doubles. Doubles because they’ve got two side chains
and two fasteners. So today we’re going to demonstrate how to affix this set of tire chains in front of me, which are typically called triples,
triples being because there are three side chains or three fasteners that fit over this larger commercial
vehicle with dual tires. This is actually a
tandem axle vehicle: two axles, one axle, two axle, tandem drive vehicle with dual tires on all four corners. So we’ll have this set of triples affixed over both tires to provide the maximum amount of traction
needed in all weather conditions or bad weather
conditions. Or when required by law, many jurisdictions
require that all tires on a drive axle have to have chains on them. So rather than affixing single tired
chains on each individual tire, we have one single unit that will actually go over both tires will have hooks on the inside, hooks on the
middle, between the tires, and a hook on the outside. So to depict how to affix these triples in a different
way that should be easier for you, all we’ll do
is just make them into typically a single tire
chain by folding the inner dual tire portion over top of the outer
tire portion. ..and we’ll drape these over the outer tire as so. When we get it roughly over the outer
tire we can now grab the inner portion of the tire chain, and get them over the inside tire Again, doing as much as we can to straighten
out the side chains and cross chains getting them as even at we can. So now
you can see our outside hook is in this position here. Our inner hook is in the same location just on the
inside here, and the hook that we have between the
duals is right in the middle. So we’ll still have
to move this vehicle ahead. After the truck rolled ahead a bit, we were able to access our inner fastener, which we can reach over top of the tire here, so we’ll do up the inside fastener. We’re now proceeding
to the fastners between the dual tires. So it is
just a simple hook which we’ll fasten here now and again, if there’s extra side chain links, just take up as much slack as you can. So
we’ll just go up and try and get to the third link here.
So size is always a consideration. Make sure that you pre fit chains before you
actually go out on the road. So we got that faster affixed between the duals, Now we’ll move on to the other faster. Again will
take up a few side lengths here and tire chain fasteners are all
different so you’ll run into various models. This model just fixes up to a side link
here as so. So as you can see now our tire
chains are pretty much on but they are still very
loose. So now we will revert to what we call these cam tensioning devices for the
side chains. This set has cam lock tensioning devices on
the inside tire side-chain as well as the outside. So you
can move around on the inside here and tighten your fasteners as much as you can. so we’ve tightened all our inside cam locks. I’ll just demonstrate on the outside how these simple mechanisms work. Just a simple twist and just continue on until we get all the cam locks tighten up. So that looks pretty good. We also have up a rubber bungee cord octopus
apparatus that we can also use to take up side
chain slack just like so. In our jurisdiction, British Columbia, the use of tire chains is regulated by traffic control devices, regulatory
signs that are mounted on the side a highway.
So that sign will tell you when to carry tire chains, what type of vehicle has to carry tire
chains, and went to affix tire chains.
