Bigge powers LR 1600

Bigge Crane and Rigging Co. used a Liebherr LR 1600/2 crawler crane at a wind farm in Ohio, USA.

With a main boom of 108 m and a 12 m fixed jib (SL3F system), the crane lifted the Gamesa G90 machine housing, weighing 75 tonnes (165,000 lb), onto the top of a 100 metre tower.

Accvording to the USA-based crane rental company, the LR 1600/2 is suited for operations in the wind power industry. The SL main boom can achieve hook heights of 117 m without the need for a derrick or auxiliary crane. "With a lifting capacity of more than 95 tonnes this configuration is ideal for the assembly and installation of wind power systems in the 3 MW class, on 100 metre towers. And with a derrick system, this kind of work is possible even on towers of 120 metres in height," added a Liebherr spokesman.
