Good Afternoon All.

I was just curious if anyone could tell me if there is any record for the
tallest lego crane model?  I have just completed the first set up of my own
version of a Liebherr LR-11200 Crawler Crane that is 18 feet tall (almost 6
meters).  There are some pictures posted at the following link.

http://brickshelf.com/cgi-bin/gallery.cgi?f=104438

Check out the Stage 3 pictures for the full setup.  I am currently waiting on an
additional order of parts to add another section to the jib, bringing the total
height to 20 feet.  I think that this will be as tall as I can go.

If anyone has any insight on this matter, please feel let me know.

Thanks--Alvin

well i don’t know if i should commit you to an isilum or add you to my “dude that rock’s, MOC list” but your model is completly awsome.

as the saying goes a picture is worth a thousand words:

Wow.

So what are the non LEGO things in it? The weights, obviously, and I'm assuming
the string. The wires from the control switches on the 9V train controller and
the snakecable covering them, presumably.

Anything else? What's the provenance of the long guys from the jib to the top of
the first boom and from the second boom bottom to the end? (I can't remember the
names of the crane parts at the mo) I am assuming those are not LEGO either
since they have to take tension and there isn't much in the LEGO universe that's
really long and can take a lot of tension.

Setting that up,doing the lift, and taking it down... all day project?

Man, can I please borrow your nice smooth level driveway?????

But seriously, nice job. I think 20 feet should be possible, it's better to add
the extra length to the luffing jib, because that reduces the weight you need to
raise (1/2 the extra weight is carried by the wheels when raising the boom).

Have you tried a SDBW configuration to see how high you can get? Lifting a
straight boom puts much more stress on everything, it's fun to try!

The guy stays are made of aluminum, and are pinned together with 3 stud long
axles. I have access to a computer controlled router table at work which i
desgned and made the guys with.  The only other thing non-lego is a bolt that
goes through the center of the turntable for stability when setting up.

The entire crane comes apart in modules, so it was set up, photographed, and
taken apart in about 4 hours.

Ross, I have yet to try the SDBW configuration, however if I add all the
counterweihgts to the Superlift, the crane will hold the boom off the ground at
0 degrees. The only reason i use the wheels is to ease the stress on the motors,
and to speed things up a bit. This puts the same stress on the superstructure as
the SDBW configuration, but does not put as much stress on the boom itself.  I
will have to try it out and let you know what happens.

By the way, I saw your stage 3, and am very impressed.

Yep, that is also the reason real cranes use wheels when raising luffing jibs.
Older cranes often had a special dolly that the tip of the jib rested on for
that purpose, but newer cranes seem to have the axle built into the jib tip, and
just have removable wheels.

My minifig scale LG-1550 can lift a 1.5 metre boom+jib quite easily without the
superlift, with just the standard ballast. But it can only raise about 1 metre
of straight boom before I have to reach for the extra ballast.

Another thing I noticed, the line for your luffing jib seems to go straight up
to the tip of the luffing derrick, I think on the real crane it is actually run
through a pulley at the base of the derrick (top of boom) first? I know most
cranes do it that way, not sure about the 11200.

Also I'd be interested in how you did the slew ring. Is it just a technic
turntable, or did you do it another way?

By the way, I saw your stage 3, and am very impressed.

Thanks! That was just a test, I can't raise it any higher at my house, but I was
happy with it.

Yes, it is supposed to go through a pully at the end of the derrick, but this
was the first time it has been put together, so I missed a few things.

Also I'd be interested in how you did the slew ring. Is it just a technic
turntable, or did you do it another way?

It is a technic turntable, and I used hinge plates and bricks along with 2 x 2
tiles to build a 24 stud wide slew ring.  I will add some pictures of it when I
disassemle the base.  My gearing is off, so the crane would not slew under its
own power, which means that i will have to do some additional work on it.  To be
totally honest, i am not all that concerned with the slewing since i dont think
that i am going to be able to make it smooth with the total 50 lbs of
counterweight loaded on the superlift dolly.

By the way, I saw your stage 3, and am very impressed.

Hi Alvin,

Congratulation to your great model, it is really impressive. And I think you have taken the world record, of the tallest LEGO crane model. The former owner of the title was me, with the height 5.20 meters, (17.1 feet) of my Gottwald AK 850-1

My record was announced at the site, AFOL Records (you will find the height 4.80 meters of my crane, due to lack of update). You can write the webmaster of the site to get your record registrated.

Good luck with the last 2 feet, Im looking forward to see the pictures.

Best regards from Denmark,

Anders Gaasedal

Alvin- WOW! What a great way to start off the new year. Awesome MOC!

That's certainly a record-breaking crane. The boom construction looks sturdy and
you've done a good job there. I think you're about to even-up with ROSCO for the
largest collection of black Technic beams :-)

Please tell us more! How is the turntable constructed? How many motors do you
have and where are they in the model? How much can the crane lift?

Thanks for the compliments!

Currently, the base of the model has been disassembeled because of problems that
I encountered with the slewing and crawling.  The motors and gearing were off,
and the crane wouldn's slew under its own power with the full 50 lbs of
counterweight on the superlift carrier, nor would it move without breaking the
technic bulldozer links apart.  This is only a small setback, and I am more
concerned with the upper body works than the carrier.  It would be nice to have
a full functioning lower works, but right now I just dont have the parts or time
to make it work.

There are currently 5 of the geared technic motors in the upper body, each one
controls its own winch.  The winches have a clutch to spool out line when
setting up the crane, and also to use auxiliary motors when setting up (for
speed reasons). The winches will pickup the main boom and jib from 0 degrees
under their own power, but it takes almost 2 hours to get to 85 degrees.  I use
auxillary motors and to speed up this process when setting up the crane. (If you
look at the following picture, you can see one of these motors:

http://www.brickshelf.com/cgi-bin/gallery.cgi?i=1045366

The turntable is made of a technic turntable in the center, and the slew ring
was made from hinge bricks and hinge plates along with some 2 x 2 plates and 2 x
2 tiles arranged in a 24 stud wide ring.  This works pretty well.  The only
drawback was because of all the counterweight that goes on the carrier, I had to
put a bolt thorough the center to keep it from turing over backwards when
setting up.  I know that that makes the model not 100% lego, but i am OK with
that.

As far as how much it can lift, that has not been tested.  When I set up this
first run, the wind was blowing about 10 mph, so the tip was moving from side to
side 6 or 8 inches.  I didnt want to add to that strain by adding a load.  I was
actually kind of surprised that it didnt turn over because it was listing so far
from left to right. If you check out the following link:

http://www.brickshelf.com/cgi-bin/gallery.cgi?i=1045348

you will see the picture of the crane set up in the SDBW Configuration.  I have
tested this to 40 lbs so far.  I think that it can handle more, but I have to do
some more work to the gearing of the motors in order for them to handle the
extra weight.  I will be sure to post some picutres of the test lifts when I get
her back together and all the bugs worked out.  All in all, though, I was quite
satisfied with the way the crane preformed for it being the first time tested.

Regards--Alvin

Mark, one site that has some good pics and a clear explanation of truss design
is http://texbrick.com and there's *lots* more on BrickShelf and elsewhere. I've
used the TexBrick truss several times in my own models, and it's quite strong.
You might find yourself making a BrickLink order or two, though...

Mark, since I have to disassemble the boom into sections to get the model back
inside, I will take some close up pictures of the boom sections and post them on
Brickshelf this evening so that you can get a better look at the design.
