Steering system tailored to field requirements

Quick manoeuvring in restricted space conditions

An electrohydraulic “steer-by-wire” steering system provides the WR with everything it takes for easy and smooth steering behaviour. The machine operator can choose among three different steering modes: straight-ahead, crab or cornering mode. Each of the three steering modes is the fastest way to reach the intended position in its specified field of application. In cornering mode, the WR is capable of performing a minimum turning radius of 4,500 mm. The innovative oversteering feature enables the rear wheels to be turned even further, allowing the WR to perform an exceptionally small turning radius of no more than 3,150 mm. This undercuts even the minimum turning radius of standard passenger cars.

Different steering modes for superior ease of operation.

Straight-ahead mode: the front wheels are steered via the steering wheel. The rear wheels remain in straight-ahead position automatically but can be steered separately via the joystick.

Straight-ahead mode: the front wheels are steered via the steering wheel. The rear wheels remain in straight-ahead position automatically but can be steered separately via the joystick.

Cornering mode: the front and rear wheels are steered synchronously via the steering wheel to permit small turning radii.

Cornering mode: the front and rear wheels are steered synchronously via the steering wheel to permit small turning radii.

Crab steering mode: all four wheels are steered at parallel angles via the steering wheel.

Crab steering mode: all four wheels are steered at parallel angles via the steering wheel.

Cornering mode with oversteering feature: once a specified steering angle has been reached, the rear wheels can be turned even further via the steering wheel. Oversteering enables even smaller turning radii to be achieved.

Cornering mode with oversteering feature: once a specified steering angle has been reached, the rear wheels can be turned even further via the steering wheel. Oversteering enables even smaller turning radii to be achieved.

The currently selected steering mode is clearly displayed at all times and can be conveniently changed via the multifunctional joystick. The highly precise steering system and free choice of steering mode relieve the operator, enabling him to focus on productivity and on ensuring that his work meets the highest quality standards.
