Provided is a windlass that prevents damage to a hydraulic motor caused by surge pressure generated inside the hydraulic motor. The windlass 26 winds up an anchor chain 27 by using a hydraulic motor 4driven by hydraulic pressure supplied from a hydraulic pump 2 via a hydraulic pressure supply unit 3. The windlass comprises: an accumulator 15 that is connected to the hydraulic pressure supply unit3 and dampens shock from hydraulic pressure; a chain counter 34 that measures the amount R of anchor chain 27 that is wound out; and an electric valve 18 for selectively setting the connection stateof the accumulator 15 relative to the hydraulic pressure supply unit 3 to an on state in which accumulator 15 is connected to the hydraulic pressure supply unit 3 or an off state in which the connection is released, setting same in accordance with the wind-out amount R.

    本发明提供一种起锚机。该起锚机不会因在液压马达的内部产生的浪涌冲击压而致使液压马达破损。起锚机(26)通过液压马达(4)卷起锚链(27),液压马达(4)利用自液压泵(2)经由液压供给路(3)供给的液压被驱动。起锚机(26)具备:蓄能器(15),与液压供给路(3)连接对在液压中产生的液压进行缓冲;链计数器(34),测量锚链(27)的送出量;电动阀(18),用于根据送出量(R)将蓄能器(15)对液压供给路(3)的连接状态选择性地设定成蓄能器(15)与液压供给路(3)连接的接通状态或是解除该连接的断开状态。
