SPECIALISED TRANSPORT Ӏ SECTOR REPORT
j for the wind power industry;
but Goldhofer has now optimised and extended the concept so that it can be used in the construction industry in general, for example for transporting concrete beams, structural components or entire bridge elements. For this purpose the trailing dolly is used in combination with a two-axle front dolly with a turntable. The added flexibility allows the dolly to be used for other purposes besides windfarms, so will give a faster return on investment for customers. Goldhofer was also showing its
FTV850 blade carrier for extra- long and heavy turbine blades. It mounted it on a four-axle, self-propelled PST/SL-E split combination(1/2+1/2) widened to 4,010 mm – a new solution designed, it says, for maximum

transformer transportation avoids overload
UK based heavy transportation specialist Collett and Sons was tasked with transporting an 80 tonne transformer 230 miles to the Harting Rig wind farm substation in Lanarkshire, UK. Three miles from the site the load had to cross Glassford Bridge, where restrictions were in place; the loaded trailer and truck combination would have exceeded the maximum permitted weight. At the bridge Collett's solution was to disconnect the loaded trailer from the 8x4 MAN TGX
tractor unit. Then two 40m wire cables were attached, connecting the trailer and primary ballast truck of the tractor. A secondary 8x4 ballast tractor unit was connected to the rear of the trailer, again using 40m cables. With all other traffi c restricted, the secondary ballast tractor reversed and the primary drove forward. This tensioned the cable, removing any slack; then both vehicles began a slow drive forward. The cables allowed the tractor unit to clear the bridge before the trailer entered it; the weight of both was never on the bridge at the same time. Controlling the cable tensioning throughout, the primary tractor unit cleared the structure, followed by the trailer, transformer and Steersman in tow. With the ability to control the trailer steering and breaking, Collett’s steersman ensured that the trailer and cargo remained within the necessary alignment whilst traversing the structure. Once clear of the bridge, and with the trailer brake applied, the secondary ballast unit took up the cable stack and crossed Glassford Bridge
sensible move on Goldhofer’s part. The explosion in windfarms has
in no way reduced the demand for moving other more traditional loads. So Cometto, mentioned above, in November 2022 sold 20 SPMT axle lines to the Hüffermann group for forthcoming heavy-duty transport missions. The self-propelled electronically
steered modular fleet is proposed for jobs in industry and bridge construction, plant and ship construction and for projects in the tightest areas. “The Cometto horizontal SPMT transport system has a current payload of 868 tonnes and is extraordinarily powerful,” says their sales manager Joachim Kolb. Hüffermanns also has equipment from Enerpac, and believes the symbiosis between the two will work well. "Due to the optimal combination possibility of the SPMT with the lifting system / JS system from Enerpac, we can optimally complement our heavy load assembly and engineering division," says Rocco Schimmel, operations manager of Eisele AG, which is part of the Hufermann group. Eisele has received two six- axle bogies, two four-axle bogies, a 368kW Powerpack Unit and another one of 129 kW as well as a turntable set for a 500 tons load as part of the delivery.
