The invention relates to the technical field of engineering machinery, and discloses a method for determining sidewise bending of a crane jib, a processor, a device and a crane. The method comprises the following steps: under the condition that a left mast and a right mast are subjected to amplitude variation to be perpendicular to a suspension arm and swing to the same swing angle, determining to enter a suspension arm sidewise bending detection state; under the condition that the first length difference between the left steel wire rope and the right steel wire rope is larger than the preset allowable deviation, it is determined that the suspension arm laterally bends towards the right side; under the condition that the second length difference between the right steel wire rope and the left steel wire rope is larger than the preset allowable deviation, it is determined that the suspension arm laterally bends towards the left side; and under the condition that the first length difference or the second length difference is smaller than or equal to the preset allowable deviation, it is determined that the suspension arm is not laterally bent. Based on the structural symmetry of the superlift device, the current sidewise bending state of the crane jib is visually recognized by comparing the lengths of the left steel wire rope and the right steel wire rope, the sidewise bending phenomenon of the jib can be quickly and accurately recognized, the accuracy is high, and the reliability is high.

    本发明涉及工程机械技术领域,公开了一种用于确定起重机吊臂旁弯的方法、处理器、装置及起重机。方法包括:在将左桅杆和右桅杆均变幅至与吊臂垂直,且将左桅杆和右桅杆均摆转至相同摆转角度的情况下,确定进入吊臂旁弯检测状态;在左钢丝绳和右钢丝绳之间的第一长度差大于预设允许偏差的情况下,确定吊臂向右侧旁弯;在右钢丝绳和左钢丝绳之间的第二长度差大于预设允许偏差的情况下,确定吊臂向左侧旁弯;在第一长度差或第二长度差小于或等于预设允许偏差的情况下,确定吊臂无旁弯。基于超起装置的结构对称性,通过对比左右钢丝绳的长度来直观地识别起重机吊臂当前的旁弯状态,实现了快速且准确地识别出吊臂旁弯现象,准确性较高,可靠性较强。
