Simple design – no maintenance The front axle is mounted at three points (1) , which pro- vides independent wheel movement. The front suspension consists of an A-frame (2) fitted to the frame structure (3) by a spherical rubber bushing (4) , hollow rubber springs (5) , shock absorbers (6) , and a cross stay (7) . Long component life and a suspen- sion that requires no regular maintenance contribute to increased uptime. A-Frame (2) absorbs the acceleration and braking forces from the front axle. It also provides independent wheel movement. The maintenance-free hollow rubber springs (5) con- tribute to high operator comfort and long service life. Four progressive shock absorbers (6) with end-stroke damping further enhance the off-road traction and com- fort provided by the three-point suspension. A cross stay (7) absorbs the lateral forces from the front axle and provides excellent stability and accurate steer- ing. High average speeds Production is heavily influenced by operator comfort. Independent wheel movement and a shock-absorbing suspension contribute to high operator comfort. As a result, the hauler can maintain higher average speeds in rough conditions for greater productivity. Low operating costs In contrast to pneumatic or oil/nitrogen suspensions, rub- ber springs require virtually no maintenance, reducing total operating costs.
