The invention relates to the field of engineering machinery, in particular to a control method for a crane, a controller, the crane and a storage medium. The method comprises the following steps: acquiring a rotation angle of the crane under the condition of determining that the crane is in a tire operation working condition; under the condition that the rotation angle is within a first preset angle range, a first electromagnetic valve is controlled to be communicated so as to control oil liquid to be guided into a first rod cavity and a second rodless cavity from a pressure oil source; under the condition that the rotation angle is within a second preset angle range, a first electromagnetic valve and a second electromagnetic valve are controlled to be communicated so as to control oil liquid to be guided into a first rod cavity and a second rodless cavity from a pressure oil source through the first electromagnetic valve and guided into the second rod cavity and the first rodless cavity through the second electromagnetic valve; and under the condition that the rotation angle is within a third preset angle range, the second electromagnetic valve is controlled to be communicated so as to control oil liquid to be guided into the first rodless cavity and the second rod cavity from the pressure oil source, and the vehicle body inclination angle of the crane is within a safe inclination angle range.

    本申请涉及工程机械领域,具体涉及一种用于起重机的控制方法、控制器、起重机及存储介质。方法包括:在确定起重机处于轮胎作业工况的情况下,获取起重机的回转角度;在回转角度处于第一预设角度范围内的情况下,控制第一电磁阀连通,以控制油液从压力油源导入第一有杆腔和第二无杆腔;在回转角度处于第二预设角度范围内的情况下,控制第一电磁阀和第二电磁阀均连通,以控制油液从压力油源通过第一电磁阀导入第一有杆腔和第二无杆腔,通过第二电磁阀导入第二有杆腔和第一无杆腔;在回转角度为第三预设角度范围内的情况下,控制第二电磁阀连通,以控制油液从压力油源导入第一无杆腔和第二有杆腔,使起重机的车身倾角处于安全倾角范围内。
