オーストリアのFuhrmann社はHardox®耐摩耗薄板を使用して軽量・頑丈な側壁を製造し、高耐久・長寿命のティッパー用側壁を提供しています。

Fuhrmann社が選んだのはHardox®耐摩耗薄板鋼板

Fuhrmann社はHardox®薄板鋼板の採用で、側面の高収率生産を実現しました。 Hardox®耐摩耗薄板は0.8 mm (0.032”) ~ 8.0 mm (0.315”) の板厚と、最大16,000 mm (629.9 “) の長さに対応します。 薄板鋼板は精密な板厚・平坦度による優れた表面品質で、工場での確かな作業性や高度な溶接を実現します。

“We have recommended that our trailer and tipper body customers use side walls in Hardox® 450 wear steel for a long time now. Initially they were produced in 4 mm (0.157”) thickness. Today we make our heavy-duty side walls in 2.5 (0.098”) and 3 mm (0.118”) thick Hardox® 450 wear sheets, which of course makes the vehicle lighter.”

Franz Fuhrmann, CEO

Hardox® wear steel has proven itself to be a premium wear-resistant material in all applications where the steel construction comes into contact with gravel, building rubble, scrap, glass granulate, excavated soil and other abrasive materials that are handled in for example recycling or construction.

“In order to be able to manufacture thinner-walled yet highly wear-resistant side walls, 2.5 (0.098”) and 3 mm (0.118”) thick Hardox® 450 metal sheets were used,” says Michael Glaser, SSAB regional manager for Austria. “With the same stability and wear resistance, the weight of the sides can be reduced by a good 37% compared to standard sheet metal.”

Hardox® sheet steel in the body’s walls is highly resistant to heavy impact despite the reduced wall thickness.

Reduced thickness offers more load capacity at the same total weight

Thinner side walls give a substantial increase in loading capacity without exceeding the allowed total weight for the vehicle. This results in less fuel needed per transported ton. And since 50% of the trips are usually unloaded, the lighter vehicle saves fuel in both directions.

Less fuel means less CO2 emissions, and less steel used reduces the CO2 footprint already in the steel manufacturing process.

The lighter side walls also have practical advantages – they are much easier to handle for the driver when they are folded up and down.

And you can go even lighter with Hardox® 500 Tuf, now also available as wear sheet. You get 50 HBW higher hardness than Hardox® 450, allowing for a thinner side wall with the same excellent wear life.

A one-piece design from sheet steel

Fuhrmann designs a variety of side wall profiles to fit different vehicles and wall heights depending on the type of load being hauled. They are often made according to customer specifications.

For rigidity and ease of production, the top and bottom rails are bent to form an integrated part of the side walls. This minimizes the need for welding, making the walls stronger and faster to produce. The entire side wall with its profiling is exceptionally resistant to impact, even from heavy rocks.

“We are very impressed by the high flatness and dimensional accuracy of the Hardox wear sheets,” Fuhrmann says.

A heritage of quality

The company Fuhrmann Fahrzeuggesellschaft m.b.H. dates all the way back to 1856. The former village smithy in the Austrian city of Steinebrunn has now evolved over six generations into a modern family business with around 160 employees. Fuhrmann exports its steel wall sides to well-known trailer and commercial vehicle manufacturers in over 30 countries. For the regional market, Fuhrmann also produces trailers of its own design for agriculture and transport vehicles for wine and fruit growing.
