The DLG has one of the largest chassis dynamometer for measuring the performance and consumption of commercial vehicles worldwide. Here, the focus is on measurements on tractors. Fuel consumption and performance measurements on other commercial vehicles and trucks complete the range of services.
The chassis dynamometer can be used to test the specific fuel and AdBlue consumption of tractors with up to around 1,000 hp. The tractors stand for the test on four steel rollers, each 2 m in diameter, which can be driven and braked by electric motors. The rollers are adjustable between 2.05 m and 6.00 m to the required axle spacing. In total, each unit consisting of a roller, electric motor and motor mount weighs around 35 t, making it stable enough to achieve maximum axle loads of 30 t, i.e. a maximum total of 60 t actual weight of the tractor. The maximum transmittable tensile load per wheel is 135 kN.
