Germany’s Energieanlagen Ramonat is a power cable installation specialist and has been calling on Goldhofer equipment to mobilise large reels internationally.
Depending on the design/length of the cable, which can be up to 2 km, the drums weigh in the range of 55 tonnes and are expected to increase to around 100 tonnes in the future. Managing director Stefan Ramonat said widths of 4-5 m are common today, but “soon it will be between 8-12 m”.
To transport these kinds of loads quickly and safely, Energieanlagen Ramonat mainly uses Goldhofer THP/SL-L heavy-duty modules with vessel bridges. The model offers an optimal deadweight-to-payload ratio and numerous combinations, along with high torsional stiffness and off-road capability. Self-propelled Addrive units can also be mobilsed to expedite projects and increase efficiencies.
To cope with the increasingly high-volume cable loads of the future, Goldhofer is working to develop a vessel bridge to accommodate an unwinding device for drums weighing up to 100 tonnes. Parallel to this, concepts are being developed for motors with synchronised drive for jerk-free cable unwinding at the installation site.
Ramonat added: “The combination of the THP/SL-L modules with the vessel bridges, which are only 450, 500 or 650 mm high and up to 13 m long, is the optimum heavy transport solution for our cable drums. It is flexible to use, highly available, and has already saved us many time-consuming detours.”
