Finland is now expanding its ambitious programme to improve efficiency in timber transport. In addition to the ongoing trials with the giant 104-tonne Scania forestry truck, Finnish authorities have approved trials for 84-tonne transport operations on unpaved forest roads.
Named Pikkujätti, or the Little Giant, the 12-metre Scania truck has started operations on behalf of the Finnish State Forest Enterprise, Metsähallitus, following approval by the Finnish Transport Safety Agency, Trafi.
“We believe that the Little Giant has the makings of a future model for timber transport,” says Ari Siekkinen, Development Expert at Metsähallitus.
The V8 Scania R 730 rigid truck has been exceptionally equipped with a shorter-than-normal cab to accommodate a longer chassis bed. The truck can carry two log bundles, which are usually 4–4.5 metres in length. An additional 2–3 bundles, depending on length, are loaded onto the trailer.
The truck features five axles, of which the first four have leaf springs and the fifth, a retractable tag axle, is equipped with air suspension springs. With this specification, the 25.25-metre truck and trailer combination truck can be manoeuvred with sufficient traction on unpaved forest roads even while unloaded. With the first two and the last axle steered, the truck can follow previously carved tyre tracks without causing irreparable damage to sensitive roads.
