Lowering and Dismantling of one of our largest Self Erecting Tower Cranes, the Liebherr 81.1k, by our team of engineers and the manufacturer in Bristol. The crane is powered electrically by generator or on 3 phase mains and has lift duties of 3.2tn at 31m radius with 31m jib, 2.35tn at 37m radius with a 37m jib, 1.9tn at 42m radius with 42m jib , 1.7tn at 45m radius with 45m jib and 1.35tn at 48m radius with 48m jib. On this project we had 48m jib. The crane under hook height was 26m but with additional inserts we can raise the height up to 40m under hook height, largest in its class of SETC.
