Abstract:
A hydraulic pilot control system having two control outputs (96, 97) to which a control pressure is appliable and having a hydraulic pilot controller (69, 70), which has a handle (81) pivotable from a neutral position in a first direction to apply a variable control pressure to a first of the control outputs (96) and in a second direction to apply a variable control pressure to a second of the control outputs (97), and whereina pressure valve (69) of the pilot controller is displaced from the neutral position by deflection of the handle (81) to generate the variable control pressure at a control output (80) of the pressure valve (69), during a pivoting of the handle (81) in the first direction and during a pivoting of the handle (81) in the second direction, the pressure valve (69) of the pilot controller is adjusted by movement of the handle, and a directional control valve (70) of the pilot controller depends on a pivoting direction of the handle (81) from a rest position to change into a first switching position which connects the control output (80) of the pressure valve (69) to the first control output (96), or to change into a second switching position which connects the control output (80) of the pressure valve (69) to the second control output (97).
