The invention belongs to the field of crane control, and discloses a rotation safety control method and system for preventing a whole crane from inclining. The method comprises the steps of obtaininga current inclination of the crane, and judging whether to enter a rotation safety control mode according to the current inclination of the crane; when the crane enters the rotation safety control mode, judging whether a safety rotation condition is met under a current hoisting working condition; and if yes, controlling the crane to execute a rotation action. According to the scheme, judgment of the rotation safety control mode and judgment of the rotation safety condition are added, when the crane performs hoisting on the uneven ground, the problem of reverse rotation of the crane due to thefact that a rotation brake cylinder is opened and then the pressure of a rotation system is insufficient is solved, and unpredictable potential safety hazards caused by reverse rotation can be avoided.

    本发明属于起重机控制领域,公开了一种起重机用防整车倾斜的回转安全控制方法和系统,该方法包括:获取起重机当前倾斜度,并根据起重机当前倾斜度判断是否进入回转安全控制模式;当起重机进入回转安全控制模式时,判断在当前吊载工况下是否满足安全回转条件;若是,则控制起重机执行回转动作。本发明方案中加入了回转安全控制模式判断和回转安全条件的判断,当起重机在不平整的地面进行吊载时,防止因回转制动缸打开而回转系统压力不足的情况下导致起重机反向回转的问题,可避免因此产生的不可预估的安全隐患。
