To provide an anchor lifting machine capable of preventing damaging of a hydraulic motor caused by serge pressure generated in the hydraulic motor.SOLUTION: An anchor lifting machine 26 is for lifting an anchor chain 27 by a hydraulic motor 4 driven by hydraulic pressure supplied from a hydraulic pump 2 through a hydraulic pressure supply path 3, and comprises: an accumulator 15 connected to the hydraulic pressure supply path 3 to buffer shocks generated in the hydraulic pressure; a chain counter 34 that measures the amount R of delivering the anchor chain 27; and a motor valve 18 for selectively setting the connection state of the accumulator 15 to the hydraulic pressure supply path 3 to an on state where the accumulator 15 is connected to the hydraulic pressure supply path 3 or an off state where the connection is release in accordance with the delivering amount R.SELECTED DRAWING: Figure 1

    【課題】油圧モータの内部に発生するサージ圧によって油圧モータが破損することのない揚錨機を提供する。【解決手段】揚錨機26は、油圧ポンプ2から油圧供給路3を経て供給される油圧で駆動する油圧モータ4により錨鎖27を巻き揚げるものであり、油圧供給路3に接続されて油圧に生じる衝撃を緩衝するアキュムレータ15と、錨鎖27の繰出し量Rを計測するチェーンカウンタ34と、油圧供給路3に対するアキュムレータ15の接続状態を、繰出し量Rに応じて、油圧供給路3にアキュムレータ15が接続されたオン状態又は該接続が解除されたオフ状態に選択的に設定するための電動弁18とを備える。【選択図】図1
