Powerful Drivelines for Graders

 

For more than 60 years, Neunkirchener Achsenfabrik AG (NAF) located in Neunkirchen, Germany, has been engineering and producing high performance drivelines working in the toughest ground and climatic conditions worldwide.
NAF´s drive solutions are modelled for their special use and application. The tough conditions in mining operations need a strong and reliable drive solution to keep productivity on the highest level for the operator. The casted design in combination with gear drive guarantee a high lifetime and less maintenance over years.

NAF enlarged the range of bogie axles for construction machines and offers a superior and cost efficient ”Made in Germany” drive solution especially for motorgraders.

With requests from the market for 260-380 hp and 27-40 t machines, NAF’s product range is continuously growing and its well-proven bogie size TAP 7600 with dynamic axle load of 255 kN at 50 km/h was expand by 2 additional bogie axle sizes:

  • TAP 7800, for dynamic axle load of 345 kN at 55 km/h;
  • TAP 8900, for dynamic axle load of 485 kN at 60 km/h.

The new sizes are perfectly integrated in NAF´s modular system to allow a high variation and customized solution to realize the perfect drive for each model. Features like NoSpin or Multi-Disc-Differential-Lock (MDDL) are available as an option. If necessary, each bogie size can be equipped with NAF’s integrated Permanent Bogie Balancing System (PBBS®) that insures an equal distribution of weight and tractive effort on all 4 wheels.

The existing range of construction bogie axles made by NAF used in small and medium size motorgraders as rear axles are availabe from model PTA 4400 (72 kN at 30 km/h), TAP 5500 (110 kN at 45 km/h) and TAP 7500 (130 kN at 45 km/h). NAF bogie axles can cover a wheelbase between 1300-1960 mm for a wide range of different tires.

NAF also offers centrally-driven front steering axles in different sizes, ready to accept different models of hydraulic motors.
