Abstract

PURPOSE: To provide a device for enabling an efficient operation and the further increase in the excavation depth, by improving a method of winding a rope.
CONSTITUTION: A rope is hung down from the rear of a front end guide sheave 63. Thus, a hanging length of the rope from the front end guide sheave 63 to a bucket 30 should be rolled into the front end guide sheave 63 as a result of bending an arm 14. This causes the hanging length of the rope to be shortened. On the other hand, an intermediate guide sheave 176 is located on an axial center being the same as a rocking center of the arm 14, and the rope is hung around said sheave. This prevents the shortening of the rope hanging length which will occur due to the bending of the arm 14.
