Case gets out of a tight spot with the 856C AWD grader

Steering innovation for the CASE 856C AWD grader

Case is set to unveil its patented combined steering functionality for its grader range, including the CASE 856C AWD model.

Case has combined industry-standard controls for the front wheel and frame articulation angle into one function that is managed by either the joystick or the steering wheel.

Combined steering uses a network of angular sensors to provide steering feedback to the vehicle control unit. It can be activated when required and used in conjunction with variable steering ratios to adapt to site conditions.

For job sites that require tight turns in confined spaces, the two functions can be supplemented by the wheel-lean function. At the touch of a button, operators can activate this functionality, making driving and grading tasks much easier.

When not required, the wheel-lean function can be disconnected from the combined steering, leaving wheel steering angle and frame articulation moving simultaneously.

Case says that precise control of the lean, steering and articulation angles are crucial for maximising efficiencies when operating in restricted areas. But, while operators are concentrating on manoeuvring the machine, they are spending less time navigating the site effectively and carrying out their grading tasks. This situation can lead to operator fatigue and reduced productivity.

This innovation will be available on Case graders in Europe from 2021.
