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.
