The invention relates to a hydraulic control arrangement for the demand-feed regulated hydraulic fluid supply of preferably several hydraulic consumers which are provided with proportionally adjustable directional control valves (12). A required amount of hydraulic fluid can be delivered by two hydraulic pumps (30, 31) via a common supply line leading to the directional control valves. A first demand-feed regulator (45) is associated with the first hydraulic pump (30) and a second demand-feed regulator (46) is associated with the second hydraulic pump (31). A return valve (36) which opens into the feed line is mounted between the first hydraulic pump (30) and the feed line (26). According to the invention, a return valve (37) that opens into the feed line (26) is also arranged between the second hydraulic pump (31) and the feed line (26). Means (90, 91, 95, 96) for regulating the power use of the demand-feed regulator (45, 46) are provided, whereby said means can be modified in such a way that the hydraulic consumers can be exclusively supplied with hydraulic fluid by the first hydraulic pump (30) or the second hydraulic pump (31).
