How to Operate a Tower Crane - Rebar Column
Sharing buttons:
testing out a little video here seeing
what it looks like from
everyone else's perspective a little
chesty on the gopro
and a stand up a column it's a pie
laster it ties into a wall
it's just all made of rebar tied
together it's probably 20 feet long
we're gonna
stand it up and send it over and set it
and we'll see what that looks like on
video
over my right hand we got hoist control
so it goes
push down for down we got
up for up and pulling back towards you
in the left left hand side we got break
for the twists that's a break for the
swing
um and then we've got uh swinging left
we just pushed the controller to the
left that was the brakes opening up
and then to the right we just pushed to
the right and reset my brake since
there's a little bit of a breeze out and
get pushed around by the wind
got it trolley in trolley out
that's how this thing runs
some cranes will have a fourth control
for
uh traveling when you're set up on rails
so that's also an option looks like my
guys are about ready
calling for hoist up here real soon
all right go ahead and pull back to my
second step and hoist up and then third
clutch and a lever 550
standing up so i'm going to trolley out
a little bit
just nice and easy get my swing over
swung a little bit
as i'm coming up and this is all a guess
from here
i'm going to slow down my hoist and it's
about to pop up
stop my trolley keep coming up
coming up we're gonna head down that
north wall
this is a decent stand far west
not as good as it gets but we're going
to go a long ways out so i'm going to
have to come in quickly
so you go into my third step which is
really fast on these
well it's not that it's really fast it's
the change between second and third is
crazy
now i'm going to start my swing because
i got power lines
on my left that i'm coming around so i
got to make sure i'm within a point
that i have marked out on the jib in my
head
where i need to go start my swing
when you start your movements you want
to get it moving
and then pick up the pace so i just
slowed down so i stay in a relatively
fast
base coming in then i slow it down the
idea is to keep some control over the
loading see that's drifting a little bit
so i take a little
more in just for fun
and i start my trolley out again
coming out kind of easy and then now
that i'm
clear of those power lines i can get
moving again
i'm not sure exactly which one we're
going to
get lined up in an area and just get out
their ways
one of the things you can see is there's
an orange
line running out there and that's within
10 feet of the power lines
these aren't actually high voltage lines
that we're dealing with out here
but they uh they are power lines so we
got to stay away from
them i'm a long ways from where i need
to be
so i'm going to start my down i slowed
down my trolley so i'm a ways away from
where i need to be
just getting it down a ways
my trolley means stop the trolley so
that's what i did there's a little bit
of drift in it it's column
so i'm going to need out you can see how
it's
not quite right taking a little bit of
the out that i know i need
even though he hasn't asked for it
and i'm probably going to need a little
bit more of my swing racks again it's
it's not straight angles it's a big
radius so it's a big curve you're
dealing with right
so i'll take nice easy bumps of swinging
to the right when he's ready and then
probably a couple bumps of trolley out
which
means just a little bit of upside
give uh nice and easy and
swinging back which counter torque
i know he was about to move out and i
set the brakes from contact
all right
yeah you're down now
you ready i might have walked on
cable down
when you're setting columns it's pretty
tight there's a lot of things to hang up
on
and so you have to gear down to a slower
gear it just won't run slow enough from
third clutch to
set a column or a pi laster like this
you can see that it's leaning out
which means that it's a bunch of weight
when it leans like that means there's a
bunch of weight that's
so the hoist up is kind of fast
even in that second clutch so i just
give it little bumps
on these old bears hoist down you go
straight to second step
unless you have a really heavy weight on
because that first uh
just really opens the brake it doesn't
really put power to the hoist
easy down inches
hi you can see my rigging starting to
get a little bit slack it's coming
in a little bit normally it's straight
out so it's coming in a little bit means
it's
and it's bouncing a bit and then you can
tell that it's getting loose
and that's setting a column on atari
