Wooden roller coaster in Sweden

The complete timber construction work will be carried out by Ingenieur-Holzbau Cordes in cooperation with Merk Holzbau (rails) and Intamin of Switzerland (drive system) – as was the Colossus ride at Germany's Heide Park Soltau fun park. This roller coaster is also being designed and calculated by Ingenieurbüro Stengel in Munich.

For the first time, SPAX full-thread screws (8x300 mm) are being used as “transverse reinforcement” in accordance with general technical approval Z-9.1-519.

Unavoidable cracks and splitting of the wood in the area of the round press-fit dowels can lead to a reduction in the load-bearing capacity of the wood. To counteract this, these screws reinforce the wood perpendicular to the grain in the direction in which the wood naturally has the weakest strength properties. In addition, the measure is expected to produce many small cracks and not one large one, which has a positive effect on the load-bearing behaviour.
