Abstract
A device includes a bevel pinion meshed to a bevel ring in rigid fixation with a pinion gear engaged with a slew ring to control rotation of the slew ring. A rotation sensor provides an electrical output corresponding to a rotational position of an input gear of the rotation sensor. A reduction gearing system interposes the bevel ring and the input gear of the rotation sensor. The gearing reduction system provides a reduction ratio enabling the rotation sensor to determine rotational position of the slew ring.
