PURPOSE: A leveling device for a jib crane is provided to reduce work time by easily performing the balancing work of a jib assembly. CONSTITUTION: A leveling device for a jib crane comprises a post (110), a jib assembly (120), a hoist (130), a drive unit (140), and a guide roller assembly (150). A rotation part (115) is formed on the top end of the post. The top of one side of the jib assembly is supported to the rotation part, and the bottom corresponds to the post. The jib assembly is horizontally extended from the post to be rotated. The hoist moves along the horizontal direction of the jib assembly and pulls up the adulteration. The drive unit is supported and coupled to the rotation part and horizontally rotates the jib assembly. The guide roller assembly touches the post and disperses the load of the jib assembly to the post. |
