PURPOSE: A rope release unit of a winch is provided to separate the rope pulled up with a roller from the roller no matter where the rope, which is pulled up by being inserted in the gap of the roller, is inserted in. CONSTITUTION: A rope release unit of a winch is equipped with a pulling up roller with a gap by uniting two hemispherical rollers to face each other. The pulling up roller is combined to a rotary shaft of a hydraulic motor fixed to a fixed frame and is rotated by the rotary power of the hydraulic motor. A filling slot(210) formed in an eject pin(200) in an ellipse shape is inserted in the gap of the pulling up roller. The pulling up roller is rotated without contacting the filling slot. A fixing hole(220) is formed in the position facing the filling slot of the eject pin. In the fixing hole, a fixing bolt(300) is inserted and the position is adjusted by a nut. |
