For the 2km route, from the old quay to the new container port, the team used a self-propelled trailer combination consisting of two 16-axle self-propelled trailers PST/SL-E from Goldhofer. Havator constructed special load distributing frames weighing approximately 80 tons per vehicle side.
First unit to move was the 610 ton harbour crane Ansaldo. Ansaldo measured 25m in length, 22m in width and 60m in height. After providing the sub-construction for the crane the latter could be loaded onto the Goldhofer self-propelled trailer combination. Then the convoy of vehicles with its total weight of 920 tons started moving. The other two cranes weighed 700t and 500t.
Havator did preliminary planning, structural calculations, production and mounting of sub-frames/load distributing frames as well as the transport and re-installation at the new site.
The heavy duty trailer combination consists of 4- and 6-axle power pack drive units which generate a tractive force of 140 kN per driven axle line. The Power packs offer an output of 490 hp each. The hydrostatic drive allows an infinitely variable and jerkfree driving, even under severest load conditions up to speeds of 17 km/h, depending on the respective gradient. The axle load per axle line of the heavy-duty module is 40 tons.
In 2006, Havator took over Finnish heavy haulier Kuljetusneliö. Last year, the Havator group purchased 120 axle lines of Goldhofer’s multiway heavy-duty modules PST/SL-E.
