Wolffkran now introduces the large topless Wolff 6031clear and 6023clear for all European core markets, as well as the new growth markets in Eastern Europe, the Middle East and Asia, and as a supplement to its own rental fleet.
Both cranes belong to the new L class of the Wolff product portfolio. This closes the gap in the 200tm range of the crane manufacturer’s programme. These new developments have been optimised for transport and assembly.
Thanks to their slim jib components, the two topless saddle jib cranes can be transported using a lot less space: the counter jib fits in one piece in a truck, the entire swivel can be transported by road with only four standard tractor-trailer rigs. Thomas Herse, chief structural engineer and project manager for the development of the new Wolff products, says “We are proud of the minimal back overhang of only 15.2m for this crane size, because it enables technically sophisticated construction under tight, for example urban, spatial conditions.”
Slotted hole connections make assembly even easier. Due to the topless design, the mobile crane requires only a comparatively low hook height.
The new unit consisting of cab and control cabinet supplies the swing gear with power immediately following assembly of the central parts. This eliminates the need for manual rotation during assembly.
The jib of the new Wolff 6023clear can be extended in 2.5m steps from 25m to 60m. In the case of Wolff 6031clear, this is possible in the same steps from 30m to 65m. Non-variable parts are also used for the jib extension for the two Wolff cranes.
The Wolff 4517city with the accompanying City tower TFS12 and the cross frames KRV 7-32 will also be shown at Bauma. The complete system consists of swivel, tower and cross frame. The entire swivel, including the 45m long jib and the tower components for a hook height of 35.5m, can be transported with only two standard tractor-trailer rigs.
Usage of the KRV 7-32 makes complicated and expensive setting of the crane in concrete unnecessary, Wolffkran says.
Upon customer request, the cross frame can be easily converted into a Cityportal, it says.
