Radio remote conveyor inclination control
If the mining machine employed is a plow it will be necessary to utilize the conveyor for horizon control providing the plow with the ability to follow the seam.
This is effected by means of the steering cylinders which are adjusted via the conveyor control. An integrated position control prevents the wave-like movement of the conveyor normally occurring when the shifting units are extended to different lengths.
By constantly measuring the actual value and comparing it to the target value the exact position of the conveyor can be determined any time. As soon as the inclination angle of the conveyor exceeds the parameterized limit value the radio-remote inclination control automatically re-adjusts.

The radio-remote inclination indicator forms the central sensor unit of the system. The built-in inclinometer constantly measures the position of the conveyor in space. The values measured are transmitted to the evaluation unit by radio.
The radio-remote inclination indicator can transmit control commands via the integrated Hirschmann sockets to an outrigger steering system.
Evaluation unit
The evaluation unit transmits measured values received via radio to the ASG and sends wireless control commands. Due to its compact design it docks direct to the RS485 interface of the ASG and does not require any further retentions or feed[...]

Parameterization unit
The parameterization unit is designed for determining the real angle of the conveyor in order to correct the measuring angle of the radio-remote inclination indicator. The unit consists of an operating and a sensor unit. The sensor unit[...]
The parameterization unit is designed for determining the real angle of the conveyor in order to correct the measuring angle of the radio-remote inclination indicator. The unit consists of an operating and a sensor unit. The sensor unit measures the actual value of the conveyor. The data measured are transmitted to the shield control unit in the form of a parameterization signal. The data are evaluated in the evaluation unit.
Outrigger control
The outrigger control consists of an H-control block of compact design. It has six functions activated via electrohydraulic pilot valves which in turn are electrically controlled from the radio-remote inclination indicator. Thus, the angle of[...]
The outrigger control consists of an H-control block of compact design. It has six functions activated via electrohydraulic pilot valves which in turn are electrically controlled from the radio-remote inclination indicator. Thus, the angle of the conveyor can be set to the desired target value.
