German crane contractor Albert Regel is using Liebherr mobile cranes from its fleet to support the construction of an extra-high voltage power line through Lower Saxony and Hesse.

Scheduled for completion in 2024, the power line will transport wind energy from the coastal regions of Germany to the south of the country. It will comprise 555 electricity pylons over a 230 km stretch. 

Albert Regel has been using its LTM 1230-5.1 and LTM 1070-4.2 cranes for the work, with over 100 electricity pylons already erected. 

“When it comes to mast construction, the crane of choice here is clearly our LTM 1230-5.1,” said Daniel Stawizki, dispatcher at Regel. “With its 75 m telescopic boom, the mobile crane can manage almost all of these jobs without the aid of a jib. We only use a 32 m fixed jib on the crane for the largest of the up to 90 m-high overhead line pylons. A few times we have also sent out our 300-tonne LTM for this.”

Regel’s LTM 1070-4.2 has supported the project, handling individual lattice tower elements on the ground and lending a hand when the components have to be upended for assembly together with the large mobile crane. 

The grid is being developed by TenneT and Regel’s cranes have been utilised on this project for three years already.
