Abstract

PURPOSE: To reduce a heavy work and danger and minify and lighten the winch by forming the groove diameter of the two or more drums with grooves provided with plural ring shape grooves for winding a rope alternately to a big diameter from an entrance to an exit side in order and providing the pushing pulley of the exit side and the brake device of the drum with groove.
CONSTITUTION: The groove diameter of two or more drums 10a, 10b with groove provided with plural ring shape grooves for winding a rope 4 alternately is formed to a big diameter from an entrance to an exit side in order and a pushing pulley 23 whose peripheral speed is faster than a rope speed and the brake device 15 of the drum 10a with groove are provided on the exit side ring groove. By such construction, a rope tension is transmitted while dropping gradually upto the near place of a final step and as the peripheral speed of the pushing pulley 23 is faster than the rope speed, a capping effect is generated and an anchor can be surely wound in even heavy. At the engagingly locking time, the drum 10a with groove is stopped by the brake device 15 and the paying out of the rope 4 can be inhibited by a friction force.
