Hey guys, my name's Jason with Mount Baker Mining and Metals and
today I wanted to give you a walkthrough of our 8 by 12 gasoline jaw crusher on
a trailer. And where gonna talk about how to set it up, how to run it, and then we'll run some stuff and show you how it works.
So the first step in setting this thing up we gotta get these trailer jacks down to
get the jaw crusher off the springs and the tires so you have a little bit more
stability. So what you got to do is lower this jack stand first, drop the front end
and raise the back end, put the trailer jacks down the back end then we'll raise
the front end and put the trailer jacks down on the front end and that way
you're off the springs from the trailer and you're all stable. So this is one of
the jack stands in the back and it's held in place by the T ring and this
drops down. And you put the ring back in, or the pin. Now it's held in place in the back.
Now you can tighten them with these four bolts which takes the slop out of the jack stand when
you're operating. There's a jam nut on each one that you can tighten up so it doesn't
come loose when you're operating.
So now we've put the two Jack stands down in the back to support the back of
the trailer, I've loosened the ones in the front, and now we can Jack the front
end of the trailer up and line up the holes for the pins for the two front
jack stands.
Now the holes are lined up, put the pin back in. The wheels are completely free off the ground.
So now I'm gonna tighten up the bolts take the weight off the tongue
stand here and we'll have the trailer fully supported on just these four jack
stands. So the RPM for this jaw crusher should
be right around 300 rpm, and that's about five moves of the jaw per second and you
can actually hear that with your ear and so when I'm operating it you'll be able
to hear the same sound that it should be operating at and the reason I say that
is because a lot of our customers buy jaw crushers with no motor on them and
then want to put their own motor on and so we govern ours to run at 300 rpm but
if you're going to build your own, 300 rpm is right about the optimum operating
speed for the jaw crusher. So this jaw crusher is run by a 21 horse
Honda gasoline engine and to start it it's real easy, you have the choke and
you have the throttle. So you pull the choke out, turn the key to start...
So thanks for watching our video on how to set up and operate an 8 by 12 jaw
crusher on a trailer. Hope you guys enjoyed it and if you have any questions
or comments please give us a call or email, all of which is in the description
below. So thanks for watching it'll see on the next video.
