Zusammenfassung:PURPOSE: An outrigger of a crane is provided to reduce the cost for manufacturing components by compacting structure of a hydraulic cylinder and an outrigger beam and to improve reliability by restraining the bending of a cylinder. CONSTITUTION: An outrigger of a crane comprises a base beam protruded onto each side of a crane body, two-stage outrigger beams installed on the end of the base beam in the extendable structure and equipped with extendable cylinders(30), a sliding unit(40) installed on each side of the second and first outrigger beams, and a jack cylinder(20) installed toward the ground. When not in use, the outrigger beams are folded. Therefore, the width of the crane is reduced.
