A powerhouse on four axles
The heart of the AC 4.110-1 is a reinforced 197 ft main boom that enables the crane to achieve extraordinary lifting capacities in its class. The AC 4.110-1 remains at a slender width of 9 ft even with 59,900 lbs of counterweight. The crane maintains a counterweight tail swing radius of only 12.5 ft even with the full 67,000 lbs of counterweight. Thanks to the superstructure shared with the AC 5.120-1, 80% of the counterweights for both cranes are interchangeable, as are the boom extensions, including one with reduced complexity. The Lift Adjuster reliably reduces load swinging during lifting and lowering.
