M.A. Mortenson Company was selected by Akuo Energy to construct Rocksprings Wind Farm, a 69 turbine, 149-megawatt wind farm 32 miles north of Del Rio, Texas. Ground conditions necessitated having a Link-Belt 250-ton (235-mt) TCC-2500 telescopic crawler crane on site as an assist crane for building and constructing 262 ft. (80 m) wind turbines with rotors (hub plus blades) weighing up to 146,000 lbs. (66 224 kg). The TCC-2500, provided by ALL Cranes, proved to be a valuable asset on the project whether lifting top can sections weighing up to 47,000 lbs. (21 318 kg), tailing rotors, building hubs or assisting with lifting the boom of one of the larger lattice crawler cranes.
