Wolffkran debuts new 8076 Compact
December 31, 2021 By Crane & Hoist Canada staff
To address an increase in prefabricated construction, Wolffkran is introducing the new Wolff 8076 Compact.
As the first 800-metre-tonne range trolley jib crane in the Wolff lineup, the crane features a maximum jib radius of 80 metres.
“We wanted to design a large yet economical crane and get the maximum capacity out of the steel structure. That’s why we opted for a low-top design, which we call Compact,” said Wouter van Loon, product manager at Wolffkran.
Despite a tower top about 10 metres lower than a Wolff Cross model, the 8076 Compact offers a maximum lifting capacity of 40 tonnes and a tip load capacity of 8.4 tonnes at 80 metres.
The new Wolff crane also features the new four-chord design of the first three jib sections instead of the usual three-chord design.
“This allowed us to optimize the transfer of forces along the jib and reduce individual components weights, resulting in around 40 per cent higher lifting capacity than with the three-chord design,” van Loon said.
Wolffkran TV 29 tower system
The Wolff 8076 Compact connects to the 2.9 x 2.9-metre TV 29 tower system. Combined with the next-largest Wolff TV 33 tower system, a freestanding height of up 100 metres can be achieved – a time-saving and economical solution for high-rise buildings or bridge projects where tie-ins are not possible. The proven and powerful 132-kW HW 40132 FU hoist winch allows for operating speeds of up to 95 metres per minute. At maximum load, the Compact is still capable of lifting 40 tonnes at 17 metres per minute.
As well. the jib of the Wolff 8076 Compact can be extended from 30 to 80 metres in 5-metre increments. A hoist rope support on the jib reduces rope slack from 10 to only 1.5 metres, lowering the risk of another crane getting caught in the hoist rope when slewing. The counter jib can be shortened from 30.3 to 22.3 metres, depending on the maximum jib radius.
