WOLFF packs upgrades into its new 6020 clear crane

Wolffkran International has replaced its WOLFF 6015 clear with the WOLFF 6020 clear, the Swiss crane manufacturer has announced. A major improvement over its predecessor is an increased tip load capacity. Two versions are available. The new flat-top saddle jib is now available as the 6tonne WOLFF 6020.6 clear and the 8tonne version WOLFF 6020.8 clear, with three different tower connections per version. "Compared to its predecessor, the 6tonne version can lift 2tonnes instead of 1.5tonnes at the tip

Wolffkran International has replaced its WOLFF 6015 clear with the WOLFF 6020 clear, the Swiss crane manufacturer has announced.

A major improvement over its predecessor is an increased tip load capacity. Two versions are available.

The new flat-top saddle jib is now available as the 6tonne WOLFF 6020.6 clear and the 8tonne version WOLFF 6020.8 clear, with three different tower connections per version. "Compared to its predecessor, the 6tonne version can lift 2tonnes instead of 1.5tonnes at the tip at a 60m jib radius, while the tip load capacity of the 8tonne version was increased from 1.5 to 1.8tonnes," said Gerd Tiedtke, product manager. Like the WOLFF 6015 clear, both versions are designed for a pure 2-fall operation.

The WOLFF 6020.6 clear has a new 28kW hoist winch Hw 628.1 FU allowing for even faster working times with partial load speeds of up to 108m/min. The 8tonne version has the 45kW hoist winch Hw 845 FU.

WOLFF redesigned the trolley by replacing the rollers with wheel flanges for rollers without wheel flanges. There is also a new guide roller on the jib to optimise the run of the trolley. The connection of the lower belt of the jib has also been redesigned to optimise the transfer of forces on the jib. This allows for the use of smaller, more practical bolts, which makes assembly easier.

Since the counterweights are no longer included as standard in the basic crane package or the jib extensions, the customer can use counterweight blocks from his existing WOLFF fleet, or buy them separately as required.

Similar to its predecessor, the 6020 clear will be available with three tower connections. It can be connected to the narrow UV 15 tower system (external dimension of 1.5m×1.5m) as well as to the wider towers TFS 20 and UV 20 (both 2m×2m).

The WOLFF 6020 clear has more galvanised parts than its predecessor, such as railings, platforms and covers, as well as specially coated bolts to prevent corrosion.

The modern slip ring system – a long-standing standard in WOLFF cranes – at the transition point between the tower and the jib permits trouble-free transmission of electrical signals.
