Recently, TNT Crane & Rigging was called out to replace an 18,000 pound transformer that had failed on a turbine at the Gulf Wind farm.

TNT used two cranes for the transformer replacement, its 500-ton capacity Liebherr 1400-7.1 and its 60-ton capacity Terex truck crane.  The Liebherr 1400-7.1 was rigged with 118 feet of main boom, a 13-foot adaption and a 207-foot luffing jib.  The transformer rests at a height of about about 280 feet.  The 60-ton Terex was used mainly for assisting in the erection of the luffing jib on the Liebherr 140-7.1.

The Gulf Wind Farm has 118 turbines and a total output capacity of 283 megawatts
