The load-sensing system is a hydraulic control mechanism in which the pressure and/or flow volume of the hydraulic pump is/are adapted to the conditions required by the consumers. In regular hydraulic circuits, the flow volume to the engine is throttled by means of pressure restriction valves or pressure control valves. The hydraulic pump always supplies the full power, even in the case of the flow volume being throttled. In some cases, this can cause high power losses. The load-sensing system, however, ensures that the pump only supplies the flow volume which is currently required for all active consumers.
