ABSTRACT:
This invention describes a steering apparatus for a tramming conveyor having at least one end articulated about a vertical axis so that said articulated end can deviate angularly in either direction about the longitudinal axis of the conveyor. The steering apparatus basically comprises a control apparatus which is coupled to an external apparatus in a manner to communicate a deviation of the articulated end of the tramming conveyor from alignment with the external apparatus. The control apparatus generates an output responsive to the steering apparatus which will result in a deviation of the articulated end either to the right or left of the external apparatus, such steering apparatus will continue the deviation of the articulated end of the tramming conveyor until the tramming conveyor is again realigned with the external apparatus.
