Overheating was yesterday: with the Turbo Retarder Clutch, Mercedes-Benz trucks can start up, manoeuvre and brake reliably and wear-free in every situation.
This is a tremendous advantage for the company Albin Borer AG from Switzerland, as its Arocs trucks transport heavy construction machinery in challenging terrain.
The truck-trailer combination edges its way up the hill swiftly and steadily. Steep slopes with alpine meadows and small woods line the route. The orange-coloured lights on the roof of the tractor vehicle flash glaringly. On both sides of the truck’s front section the red-and-white warning flaps are extended.
The three-axle tipper pulls a four-axle low-loader trailer from the vehicle manufacturer Müller-Mittental. On board the trailer, securely lashed with mighty steel chains, is a 36-tonne Case crawler excavator. A narrow side street branches off at a sharp angle on the left-hand side. And the drop-off destination for the huge construction machine is at the end of that.
Plenty of reliable torque.
All manoeuvres are carried out smoothly and confidently. Ruedi Bringold is a highly experienced driver. His truck is one of the best too: the Arocs 2663 6×4 took the steep challenges in its stride. With an output of 460 kW and a maximum torque of 3,000 Newton metres, the 6-cylinder in-line OM 473 engine has sufficient power to move the gross combination weight of almost 70 tonnes up the hill. Manoeuvring in a very confined space on an extreme incline is also possible without Bringold having to worry about the clutch overheating or the heavy-duty combination breaking down in the middle of the road.
The reason for the driver’s calmness is a technical innovation. His employer, Albin Borer AG from Erschwil in Switzerland, gave his approval for the installation of a special feature in the company’s Arocs: the Turbo Retarder Clutch.
“We frequently had problems in extreme situations with overheated clutches and brakes. Since we began using a Turbo Retarder Clutch in the Arocs operated as a haulage vehicle for our heavy construction machinery, those days are gone. The system fully meets our expectations”, says Fleet and Machinery Manager David Streiff, who used to drive trucks himself. The Arocs of Albin Borer AG. Watch the Video at RoadStars.
