ジブ起伏装置。 In a tower crane, a tower is attached to the crane body so that it can be lifted up and down, a jib is attached to the front end of the top of the tower so that it can be lifted up and down, and the jib is hoisted by winding and letting out a hoisting rope. A swing lever consisting of a frame-shaped member is attached, and the other end of the jib-side guyline is connected to the tip of the jib, and the other end is connected to the bridle-side guyline, which has one end connected to the bridle on the undulating rope side. A guide roller is connected to the tip of the swing lever and arranged above the top of the tower to support the bridle-side guy line so as to maintain a set angle with respect to the swing lever when the jib is tucked in. Jib hoisting device.
