I'm a rigger for Wyatt Field Services. We're going to start assembly on the 36000 next week at Lyondell-Basell which was, until earlier this year, Lyondell Houston. We're replacing the Coke Drums at the 736 Coker. I believe the biggest lift is a little less then 800T w/rigging @ a 170' radius w/520' boom.
We did the same thing at Shell Deer Park last year. The biggest lift there was 820t @ 160', 420' boom.
Camille, the owner of Deep South, designed the Versa-crane series himself.
What Big Iron points out is mostly true. The 'Terex-Demag 8800-1' has 1764t capacity, but the 'Terex-Demag 8800-1 Twin' has a capacity of 3527t US. The thing is that the "twin" version is a ringer so it isn't a true crawler i.e. it can't pick and carry 3500t. What Big Iron also fails to acknowledge is that he copied and pasted part of my reply from
this forum word for word. He even used the pictures that I myself uplaoded to Imagevenue.
Anyway no harm done. Conclusion - the LTL 2600 is the only true crawler on that list and the Terex-Demag 8800-1 is a 1764t crawler but the twin boom 3527t version is a ringer. So the LTL 2600 is the biggest crawler crane there is as of right now.
The interesting thing is that those are just the rated capacities of these cranes. The only thing that caps them is the size of the drum and the number of parts of line that they can use. So if they could use a bigger drum with more cable then they could put more parts of line and raise the capacity. The boom strength and counter-weights are plenty sufficient to go well beyond their rated capacities, they simply just can't put anymore parts of line.
