We have been with a Liebherr Tech all week. Some good stuff came out of it. But this is our third Liebherr. 1-2 days would have been enough. We are getting everything rigged to suit us. Order some plastic outrigger pads. Building storage boxes etc.

it is pretty sweet. I dread the first dent. In 4 wheel steer it was turn twice as short as my pickup!

I have a different operator in mind. My son typically is on one of my projects and we have a different crane we leave on the job site long term. This new crane will be primarily custom rental or a taxi crane

The rental outfit I worked for had a 3 axle krupp about the same size . It was the busiest rig there . Who ever is on it better like lots of hours . Once your customer base see's what it can do I predict it will be a money maker .

That new crane has more stickers on it than a old ironworkers hard hat.

Does it cause cancer in the state of california too? Or is it just the standard "Don't be stupid because you'll get hurt" in german, french, english, dutch, flemish, and hieroglyphics?

lets hear the dimensions:

Boom length, jib, capacity at 20' radius for unloading a truck, and 100' radius for setting a truss, HVAC unit, or steel out there. And did you run it first? Or let the new operator of the machine get the maiden voyage?

Just leave the lid open on that back aluminum box and spin around and rip the lid off with the counterweight, get the first accident out of the way.

Looks like it would be more roomy for mounting counterweights on the deck than most liebherrs, with that narrow counterweight and the distance between the cab and the upper deck. The 1100 liebherr I was around- the counterweight was right on the cab stacking weights.

C/W 26,500
Boom length: 131.2'
Jib: 31.2' or 52.5'
Best capacity at 20' is 69,000#
Best capacity at 100' R is 5,900#
Best capacity at 100' R with 31.2' Jib 0 degree offset is 5,900#
Best capacity at 100'R with 31.2' jib at 20 degree offset is 6,500#
40 degree offset is 6,300#
Best capacity with 52.5' jib at 0 degree offset is (I'm missing that page)
20 degree offset is 5,600#
40 degree offset is 5,300#
Greatest radius found in the charts is 155'

Actually the crane hasn't left the yard yet. We've all run it a bit.

I bought this crane to mimic our 60T Grove. Newer crane. Second crane of similar size etc. Info on the 60T below for comparison

C/W 16,500
Boom length: 110
Jib 33' or 56'
Best capacity at 20' is 68,250 or
Best capacity at 100' is 3,600# off the main
Best capacity at 100R with 33' jib 0 degrees is 4,350, 25 degrees is 4840, 45 degrees is 4,950
Best capacity at 100R with 56' jib at 0 degrees is 4,320, 25 degrees is 3830 and 45 degrees is 3,260
Greatest radius found in the charts is 145'

Another interesting comparison is running a shorter boom n the 1055 to compare against the 60T Grove with full live boom. I'll use the 112.1' boom for the Liebherr.

20'R on the Grove is 24,000#
20'R on the Liebherr is 36,400#
50R on the Grove is 16,000#
50R on the Lierbherr is 18,200#
75'R on the Grove is 7,800#
75'R on the Liebherr is 10,100#.
100'R on the Grove is 3,600#
100' R on the Liebherr is 5,900#

An interesting side note on the pin and latch (I'm familiar with this as we run other P&L systems. Take the 112' boom. They show 2 ways to achieve it, starting with section 1 (next to the base section)
#1-92%-92%-92%-46% OR
#2- 46%-92%-92%-92%.

Configuration #1 is the best choice for up to 40' R. At a 40' R they are both rated at 23,000#
Configuration #2 is the best choice for anything greater than a 40' R.

Personally I think it has to do with keeping the heavier boom sections closer to the C/L of the crane at higher radiuses. As a matter of course we typically set the crane up as close as possible, measure the radius, determine the minimum boom length needed then look for the best chart. If weight is No problem at all, we may go to the next boom length to assure we don't run out of boom clearance.

On several occasions I compare different cranes we run with different C/W packages. C/W seems to be the biggest factor in capacity. For instance, our 165T we can run 62,800# with one load. The second load of C/W consists of two 12,800# cheek weights. Our 190T we can only run 60,400# of C/W with one load. The second load consists of two 21,000# cheek weights. Most times our 165 T will out perform the 190 with one load of C/W. But of course the 190 with 2 loads will always out perform the 165 with 2 loads.

One thing I'm not sure I like is the winch pull. Only 10,000#. As of now we intend to use the single sheave block at most times. That will allow us a 3 part line, or max pick of 30,000#. The 60T has a 16,000# winch pull, and we also run a single sheave block on it most times. We do have a 3 sheave block for the new Liebherr. Next problem is finding a place to store in on board. Not much room left.

I love this chit.

I love how compact that thing is, and combined with it's chart, wow! It'd fit right in my current building just fine.

So where do the Koehring and P&H operators fit in that bunch?

Oh- I've got one of those P oor & H ungry' s . Beggars can't be choosers.

I bet crane op would put boom truck operators in a class of their own
Right now I'm settling for things that run.:rolleyes:

Actually, if its got a engine and levers, I'm game for taking a run at it, as long as it has a seat. I ain't one for those stand up and operate rigs. It taxes my concentration levels. Kinda like trying to walk and chew gum at the same time. A guy has to know his limitations.
