In Germany, heavy-duty logistics firm Wiesbauer used a Cometto SPMT combination of 2 x 12 axle lines in a side-by-side formation to help unload a 318-tonne generator and a 335-tonne gas turbine from an inland vessel in Marbach, close to Wiesbauer’s HQ in Bietigheim-Bissingen.
The components were lifted out of the vessel, over a building, and onto the four-file SPMT combination by two crawler cranes: a Demag CC 2800 from Wiesbauer, and a Liebherr LR 1600 from the crane service provider Neeb.
The tandem lift also required the two cranes to reverse in synchronisation on mats that had been laid out.
Once on the SPMT the load, with a total width of 5,330 millimetres, was manoeuvred between the two crawler cranes. It was driven by two power packs with outputs of 129 kW and 202 kW.
The combination then performed a 90-degree carousel drive and positioned itself for cargo pickup. Following another 90-degree carousel drive, the combination passed back between the cranes and onto the road to the coal-fired power station in Marbach am Neckar.
Having arrived there, the crew had to negotiate one final bottleneck near the works gate. Cometto said this was not a problem as its SPMT’s electronic steering system enabled millimetre precision.
For this cross-hire-rental operation, Wiesbauer procured extra SPMT axle lines from the vehicle fleet of Schares Autokrane GmbH.
