Most powerful crane in the fleet – Wasel extends crawler crane portfolio with LR 11000

For this job, the crane was set up with the special SL10DF2BV wind turbine system - 162 metre main boom, twelve metre fixed jib, 210 tonnes of turntable ballast, 90 tonnes of central ballast and 450 tonnes of derrick ballast. "The benefits of the V-Frame and VarioTray when working with suspended ballast in the wind industry were clearly demonstrated during this very first job," continues Schmidt.

The V-frame ballast system is a hydraulically adjustable folding frame which enables the ballast radius of the LR 11000 to be infinitely adjusted between 13 and 30 metres. A rigid ballasting system is no longer required for large radii. VarioTray is a small ballast pallet, which can be unbolted quickly and easily when necessary. This avoids the need for the tiresome stacking and unstacking of ballast slabs. The large ballast pallet is only required to raise and lower the lattice boom.
