In a hydraulic control system (S) with a pump (15), a selector valve (W) and at least one further, to a pressure line (32) connected to the proportional control spool (49) downstream of the selector valve (W), a pressurizable from Lastdruckabgriffen load pressure signal circuit (20 ), which is connected to a support system (F), and a pressure limiting valve (45) containing inlet pressure connection (Y), wherein at least one shuttle valve (47) either the preprinted circuit (Y) or a Lastdrucksignalabgriff further proportional control valve (49) with the conveying control (F) connecting the pressure relief valve (45) on one in a control position (a) of the selector valve (W) integrated control pressure connection (V) in the selector valve (W) itself with a Lastdrucksignalabgriff (36) of the pressure line (32) and said shuttle valve ( 47), and is between the load pressure signal tap (36) and said shuttle valve (47) and the control pressure connection (V) arranged in a control-pressure restrictor (39).
