Deck crane state determination device, deck crane system, and state judgment method of deck crane

摘要

Problem is to grasp the state of deck crane accurately.Deck crane state judgment deviceA deck crane condition determining device disposed on a deck of shipsIn a hydraulic circuit including a hydraulic pump for driving a deck craneHydraulic pump speedA measurement value acquisition part which acquires a measured value measured at least one of the pressure in the hydraulic circuit and the flow rate of the working oil flowing in the hydraulic circuit at predetermined time intervals, andWhen the supply of the driving force to the hydraulic pump is stoppedBased on the decrease in the measured value over time after the supply of the driving force is stoppedIt is equipped with a judgment section for determining a failure prediction of the hydraulic pump.Diagram
