How to operate
A Concrete Truck
Mr. John Tutorial: Operations of a Concrete Mixer/ Ready Mix Truck
Sharing buttons:
good day so I'm going to do is a quick
walk through the functions of a concrete
truck and I have to unload a little bit
so I'm going to show you how we do this
here's the barrel where the concrete is
in the water reservoir which is an old
diesel tank converted and that's where
we keep the water it's under the same
freshman at the brake system uses the
water pressures at 110 psi this is the
main line going through the tank we're
going to open that up
you see the line runs back here pennant
splits to a garden hose for the bottom
for washing around the back of the truck
and another garden hose at the top for
watching in the hopper and then
line the fat line here that goes
directly into the hopper panic trotted
up with some concrete but that's worth
adding whatever water is needed to get
the desired slumps which is another word
for the desired consistency or thickness
of the concrete
we have a remote control and as you see
here on the top we've got the barrel
direction right now the barrel is going
in a clockwise rotation which means the
concrete is mixing anytime the barrel is
going in this direction it's mixing if
it goes opposite in the silent clockwise
position you will be unloading you see
those chains up there those signs are
with either draws a Pollock in or draws
the product out
now under the barrel direction we have
the rabbit the turtle for the speed of
the barrel I can speed it up
what now
usually when you're mixing you're going
down the highway you have it turning at
a 2 to 3 rpm as 2 to 3 revolutions per
minute to maintain your mix and then we
have the
the remote for the shoot to raise it up
- hydraulic system order lower it down
there are you
and then we have the lock for this shoot
right now I need to unlock it it's
locked right now so it doesn't move
around now I'm unlocking it because I
have to dump some product out we unlatch
it and then we hold it open and then we
lock it again see it's locked that won't
go anywhere is it this break right on
the top here and that's how it locks
into position we have a hopper button
down here and that raises and lowers
that hopper right there so you can
respect your concrete for its slump
consistency and then we have a freeze
button bottom right hand side here I can
make the barrel stop momentarily there
we go
now it stopped and I'll get it
not what I have to do is I got a hose
down the back of the truck of the chute
anytime you're going to pour any
concrete got a wet everything down so
the concrete doesn't stick to it
so we wit her down what the shoot-down
put the hopper down here we go put the
back of the truck down here I know
I got wet on the camera okay you got
everything wet it down the hose back
okay now I'm going to show you the
inside of the drum climb up the ladder
always three points of contact
this is the hopper this is where the
product gets loaded into a barrel look
at it in here
the whole thing
other lower home
it's going to vote
what we call wind rose those wind rose
their dark free ones this is waste
product this product that either was too
much for the customer or in my case it
was in the barrel for three hours and
that they lose like it's a term they
call losing the concrete they can't work
with it anymore
and you can't add water to it anymore it
just takes off so I had to add a lot of
water to it just so it wouldn't harden
up in the barrel now we're going to make
a window here I'm going to drive really
slow and pouring it out this is a quad
axle Kenworth
we have to steer axles in the front
and the Rome is a 10 meter drum it's a
10 cubic metre capacity
alright go in the truck do we got to do
and of course once we're unloaded of the
product we have to wash that barrel so
right now as you see the barrel is
turning in a clockwise position
so here's the remote and I turn hit this
button here it's going to change the
direction and you going to see it turn
the other way
pushing brakes put the truck in below
here and watch the shoot out of the
chute
once this dries
gets picked up through a crusher
I think that's the crusher right there
and the
recycling
that looks like it's pretty much all
it's gonna glow set the bridge
and then we go back and start our
cleaning
put my barrel back in
now when you're cleaning the truck you
do the same thing as a shower yourself
you start at the top and work your way
down
tie them up fall away
and both in the mud
here
