A pivoting support 7 is attached to the distal end portion 5a of the distal boom 5 of the telescopic boom 3, which is attached to the base 2 so as to be vertically movable and the distal boom 5 is telescopically connected to the base side boom 4. jib 6
is pivotally attached to the jib 6 so as to be able to rise and fall freely in the vertical direction, and the jib 6 is provided between the jib 6 and the tip boom 5.
A stopper device 9 is provided to prevent the jib from tilting downward by more than a predetermined angle with respect to the tip boom 5, and furthermore, one fixed end 10a side is fixed to a proper position of the jib 6, and the other free end 10b side is fixed to a proper position of the jib 6. A sheave 21 is attached to the boom 4 side on the base side, detouring above the pivot portion 7 of the jib 6.
, 22, the jib hoisting operation cable 10 is installed so as to be reversed toward the tip boom tip 5a side, and is suspended from the tip boom tip 5a on the floating end 10b side. A main hook 12 is hooked, and by winding and operating a winch device 11 for operating the main hook 12, the fixed end 10a of the cable 10 is pulled, thereby changing the inclination angle of the jib 6 with respect to the tip boom 5. A crane device with a jib, characterized in that the crane device is configured to be adjustable.
