Wolff to launch new luffers

German based tower crane specialist Wolff Kran will launch two new luffing jib tower cranes and a brand new tower system at Bauma.

The new luffers – the 630 B and 700 B have a maximum capacity of 42 and 50 tonnes respectively and completes the company’s B range of medium to heavy luffing cranes.

The new cranes incorporate the technology and features first seen on the 355 B, at Bauma 2007. Key points are the innovative counterweight design, and lighter weight components for easier transportation and erection.

Dr. Peter Schiefer, managing partner said: "We are proud, that today we are able to offer the most suitable slewing tower crane for every construction site, anywhere in the world, as well as cost-effective solutions for transportation."

One of the new cranes will be on display mounted to the company’s new system 23 tower system. The new tower system boasts more compact dimensions allowing sections to be shipped in a standard 2.3 metre container. In spite of its more slender dimensions Wolff says that the new tower outperforms its 2.5 metre tower system in many areas.

The new tower incorporates higher strength steel and redesigned connection points. It offers a free standing height of 112 metres for cranes up to 700 m/t and includes a new climbing frame that can be removed after a climb has been completed for use on other cranes. The new system can also be mated with the 2.5 metre tower system.

Finally the company will unveil a new heavy duty conventional saddle jib crane, the 450 m/t 8033cross. The company says that at this larger size it does not believe that a topless/flat-top design offers enough advantages for the extra weight of its main components. The top mast on the new crane is just seven metres around four metres higher than a flat-top.

The benefits of the new design include lighter weight, easier assembly and a lower cost in comparison to older conventional or large flat top cranes.
