<p>A hydraulic pilot control system having two control outputs to which a control pressure can be applied and having a hydraulic pilot controller, which has a handle which can be pivoted from a neutral position in a first direction and in a second direction, and a pressure valve that can be displaced from the neutral position by the deflection of the handle. During pivoting of the handle in the first direction and during pivoting of the handle in the second direction, the pressure valve can be adjusted with the same effect, and wherein there is a directional control valve which, depending on the pivoting direction of the handle, connects a control output of the pressure valve to the first control output or to the second control output, whereby a behavior of the pilot control pressure which is symmetrical with respect to the deflection of the control lever in the two directions is adjustable in a simple way.</p> |
