A hoist having a motor and controlling the motor to raise and lower a hoist load comprises: an operation information acquisition unit for acquiring operation information of the motor; and a state estimation unit that estimates the state of the hoist on the basis of the operation information acquired by the operation information acquisition unit and a state estimation formula learned so as to be able to estimate the state of the hoist. The state estimation formula is composed of a common estimation part irrelevant to the type of the winch and a type inherent estimation part different for each type of the winch.

    本发明的具有电动机并控制电动机进行吊重的起升和下降的卷扬机,其包括:获取电动机的运行信息的运行信息获取部;和状态推算部,其基于由运行信息获取部获取的运行信息和学习成能够推算关于卷扬机的状态的状态推算式,来推算关于卷扬机的状态,状态推算式由与卷扬机的机型无关的共用推算部和按卷扬机的每个机型而不同的机型固有推算部构成。
