New low top tower crane from Wolff

Wolffkran has launched a new 800 tonne/metre low top tower crane, the Wolff 8076 Compact.


The first Wolff saddle jib crane in this class, the new crane has been designed to meet the growing demand to lift heavier prefabricated building components and modules. It features jib lengths of up to 80 metres, with a jib tip capacity of 8.4 tonnes.
Maximum capacity is 40 tonnes at a radius of up to 28.2 metres on just two falls. Also new is the four chord jib structure, which transitions to a three chord structure after the first three sections. The company claims that this concept increases capacities by up to 40 percent over an all three chord jib. The counter jib can be configured with a standard length of 30.3 metres for optimum performance, or 22.3 metres when space is an issue. Even with the shortened counter jib with a 55 metre jib, the tip capacity is a healthy 16.6 tonnes.
The first three sections have four chords, while the rest of the five metre jib sections have three chords


The 8076 Compact is designed to be used with Wolff’s 2.9 x 2.9 metre TV 29 tower system providing a free standing height of up to 100 metres. The crane is equipped with the company’s 132kW HW 40132 FU hoist winch provides line speeds of up to 95 metres/minute, or 17 metres a minute with the 40 tonne maximum capacity.

Standard features include electronic overload protection with Wolff Boost, an anti-collision interface, fine drive modes, automatic power optimisation of the trolley and hoisting gear, and the Wolff Link remote maintenance system with a real time view of the crane display.

Product manager Wouter van Loon said: "We wanted to design a large yet economical crane and get the maximum capacity out of the steel structure. That is why we opted for a low top design, which we call Compact. Despite a tower top around 10 metres lower than that of a Wolff Cross model, the 8076 Compact offers a maximum capacity of 40 tonnes and a tip load capacity of 8.4 tonnes at 80 metres. And that as a pure two fall crane, making the 8076 Compact not only the strongest saddle jib crane in our range but also best in class compared to its competitors."

“The four chord design of the first three jib sections instead of the usual three chord design, allowed us to optimise the transfer of forces along the jib and reduce individual components weights, resulting in around 40 percent higher lifting capacity than with the three chord design,”
“We are also evaluating a heavier lift version of this model, as well as one with a longer reach. Both models will be designed around the same basic components of the new Wolff 8076 Comp.”
