KR Wind expands fleet
01 April 2008
Wind turbine installation company KR Wind has ordered a second Liebherr LG 1750 lattice boom mobile crane.
The Danish company is a joint venture between heavy lifting and transport company Mammoet, in Holland, and building contractor Enggaard, in Denmark. So far KR Wind has erected 5,000 wind power turbines and has one of the world's largest heavy-duty crane fleets at its disposal, according to Liebherr.
The LG 1750 is due for delivery in the first quarter of 2008 and will complement KR Wind's four Liebherr LG 1550 lattice boom cranes, the latest having been delivered in November 2007.
The model's SL main boom system, without derrick, offers a lifting capacity of 100 tonnes with a hook height of 122 m. This is ideal for three megawatt (MW) wind turbines with a hub height up to 110 m, explained Wolfgang Beringer at Liebherr. With derrick and suspended ballast, plus a fixed jib, the crane can lift 100 tonnes up to a hook height of 152 m. With shorter booms, lifting capacities of up to 150 tonnes are possible, which is suitable for 3.5 to 4 MW turbines, Beringer added.
