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.
