A multi-function directional handle with control elements mounted for turning in both directions is arranged as a single structural unit, in which unit an axially supported control spoke with hand-grippable, individually movable control levers at its ends is provided adjustably fixed in a position within the region of grip in front of the driver's seat of a construction machine. The control levers each define an opening, wherein finger-displaceable dump lever is mounted in each such opening, the axes of swing of the control and dump levers extending, approximately parallel, to the pivot axes of the controlled tool parts, and the direction of turn of the human control movements agreeing with that of the movements controlled. |
