New dimension in crawler cranes: Maximum lifting capac-ity of 3,000 tonnes
With a maximum lifting capacity of 3,000 tonnes and an outreach of 12 metres, the LR 13000 represents a new dimension in size for crawler cranes of conventional design. The most important area of operations for this new flagship among Liebherr crawler cranes is going to be power station construction. The LR 13000 provides a maximum system length of 246 metres, which is achieved by the configuration of 120 metre main mast and 126 metre luffing fly jib. This attains a maximum hook height of 240 metres, with an overall operational weight of 3,500 tonnes.
The new LR 13000 is the only crawler crane in this size class which can operate even without derrick ballast. This is achieved thanks to an extremely powerful slewing ring, developed and manufactured by Liebherr themselves. This slewing ring can transfer high torque values, by contrast with solutions from other manufacturers with ringer systems on the crawler travel gear.
In order to ensure economical transport of this giant, no single component exceeds a transport weight of 70 tonnes. A crawler carrier is over 3.5 metres high, 20 metres long, and weighs about 210 tonnes. The track, weighing 82 tonnes, is taken off, and after being dismantled can be economically transported in containers. The track carrier, at 128 tonnes, is divided into halves and travels on two low-loaders.
At the Bauma 2010, Liebherr are showing the hook block of the LR 13000, weighing 111 tonnes and 9.7 metres high, suspended on the LR 1600/2-W crawler crane.
