ABSTRACT:
A new method for controlling movement of a digging dipper includes providing an earthmoving machine with two drive systems for moving the dipper along two respective paths. Also provided is a control apparatus having a reference axis and a knob mounted for movement between a first, repose position and a maximum position spaced from the repose position by a maximum displacement dimension. The knob is displaced along a control axis to a second position which is spaced from the repose position by an actual displacement dimension less than the maximum displacement dimension. The drive systems are energized and the dipper is powered along a digging axis generally parallel to the control axis. A new apparatus for controlling movement of the dipper has a single control knob having a repose position and also has first and second motion transducers mechanically coupled to the knob. In a Cartesian coordinate system, the repose position is at the origin, the first transducer provides a first output signal when the knob is displaced along the "X" axis and the second transducer provides a second output signal when the knob is deflected from the repose position along the "Z" axis.
