For around one year, the IJsselmeer (Lake IJssel) in the north of the Netherlands was the scene of an unusual job for a Liebherr LR 11350 crawler crane. The second most powerful crawler crane model from the plant in Ehingen erected the complete ?Westermeerwind? wind farm from a massive jack-up platform. Crane contractor Mammoet, a global player in the heavy transport and crane industry with extensive experience in the offshore wind industry, completed the last of the 48 Siemens wind turbines on schedule in February.
