Abstract: To provide an engine lug-down suppressing device for hydraulic work machinery, capable of suppressing deterioration in operability of a hydraulic actuator when the hydraulic actuator is caused to operate quickly from a stopped state. Pilot pressure to a tilting control unit of a variable displacement hydraulic pump is controlled by a solenoid valve. A controller controls the solenoid valve in accordance with a target rotational speed signal from an input unit. This control differs according to whether or not a detector detects the pilot pressure created by an operating lever device. In an entire range of the target engine rotational speed, pump absorption torque at the time when the pilot pressure is not detected, falls within a range equal to or smaller than pump absorption torque at the time when the pilot pressure is detected, and is set to approach the pump absorption torque at the time when the pilot pressure is detected with an increase in the target engine rotational speed.
