Renewable energy and specialty civil construction company IEA Constructors (IEA) used four Manitowoc crawler cranes, two MLC650s and two MLC300s, for the installation of 200 turbines at a wind farm in Texas. Configured with 331.4ft (101m) of main boom with a 24.9ft extended upper boom point (EUBP) at 28° offset, and outfitted with 661,000lbs (300t) of counterweight, the two 650t MLC650 crawler cranes helped set upper mid tower sections, spikes, blades and V120 nacelles. Performing these lifts on each pad meant the cranes had to travel from site to site fully configured, covering distances of several miles each day. The practice causes significant undercarriage wear and is a cost consideration for contractors.
