徴とする水平ジブ式クレーン。[Scope of Claim for Utility Model Registration] A jib is attached to the mast so that it can be driven and rotated about the vertical axis at a midway point in the longitudinal direction while extending in the horizontal direction. In a horizontal jib crane equipped with a trolley equipped with a hook and a counterweight on the other side, the counterweight is moved in the longitudinal direction of the jib by a drive mechanism. The jib is movable by driving, and is provided with a center of gravity position measuring means for measuring the position of the center of gravity of the load applied to the jib, and the position of the center of gravity is set on the trolley side based on the position of the center of gravity measured by the center of gravity position measuring means. When the center of gravity has moved more than the set amount, the counterweight is moved away from the mast, and when the center of gravity has moved more than the set amount, the counterweight is moved closer to the mast to bring the center of gravity within the set range. 1. A horizontal jib type crane, further comprising a control mechanism for operating the drive mechanism to maintain the horizontal jib type crane.
