Wolffkran Wolff 6020.6 clear

After almost a decade, Wolffkran has launched a new series, Wolff 6020 clear, a 140mt flat-top tower crane to replace its existing WOLFF 6015 clear series which was introduced to the market in 2008.

The new flat-top tower crane will be available to the customer from September 2017. It comes with a 6-tonne version, WOLFF 6020.6 clear and the 8-tonne version, WOLFF 6020.8 clear. Both models come with three different tower connections, which can be connected to the narrow UV 15 tower system as well as to the wider towers TFS 20 and UV 20.

Wolffkran engineers have also redesigned the trolley to optimize the run of the trolley. The rollers will now come without wheel flanges, but an addition of a new guide roller on the jib instead.

The connection of the lower belt of the jib has also been redesigned to optimize the transfer of forces on the jib. This allows for the use of smaller, more practical bolts, which makes assembly easier.
