Liebherr has developed an innovative concept for erecting LR 1600/2 crawler cranes with long wind power boom systems efficiently and safely. Using the mass of an LTR 1220 telescopic crawler crane as the counterweight significantly reduces the amount of ballast that has to be transported and eliminates ballast handling on site.
The new process was particularly developed for use in the wind power industry. A large counterweight is required on the crane for the erection of long boom systems whilst the derrick ballast can be completely removed or reduced to just a few ballast plates for the actual hoist. The innovative erection concept from Liebherr makes it possible for the first time to use the weight of an auxiliary crane as derrick ballast during the erection process. This eliminates the need to transport and handle the ballast plates since they are now redundant. An auxiliary crane is generally available on the site anyway to complete setting and light hoisting work.
