A towing apparatus for a ship concerning the present invention uses an air motor mounted on a drum to control rotation speed of the drum and has a speed reduction brake function to reduce rotation speed of the drum as well, so it can safely tow the ship. The towing apparatus for a ship comprises: a drum which winds a mooring rope thereon and is permitted to rotate, an air motor which is connected to the drum and rotates clockwise or anticlockwise and provides torque, an air pump which supplies compressed air to the air motor, and a control valve which is installed in an air line between the air motor and air pump and is capable of switching between primary, secondary and tertiary positions. The control valve rotates the air motor clockwise in the primary position and anticlockwise in the secondary position and rotates the air motor by the torque generated when the mooring rope is released in the tertiary position. |
