The invention discloses a rotation angle verification method and device and a crane, the method is applied to engineering vehicles including rotation equipment such as the crane, and the method comprises the steps that after the rotation equipment is started, whether the engineering vehicles undergo a specific driving process or not after the last rotation equipment operation is finished is judged, and if yes, the rotation angle is verified; whether the difference between the rotation angle of the rotation equipment and the calibrated zero-degree rotation angle exceeds a preset value or not is judged; and if the engineering vehicle is subjected to a specific driving process after the last rotation equipment operation is finished and the difference between the rotation angle of the rotation equipment and the calibrated zero-degree rotation angle exceeds a preset value, first prompt information is generated to prompt that the rotation angle of the rotation equipment needs to be calibrated again. By judging whether the engineering vehicle is subjected to the specific driving process or not and whether the difference between the rotation angle of the rotation equipment and the calibrated zero-degree rotation angle exceeds the preset value or not, recalibration of the rotation angle is carried out, and therefore calibration efficiency and accuracy are improved.

    本申请公开了一种回转角度校验方法、装置和起重机,所述方法应用于起重机等包含回转设备的工程车辆上,该方法包括:回转设备启动后,判断工程车辆在上一次回转设备作业结束后是否经历特定行驶过程,以及判断所述回转设备的回转角度与标定的零度回转角之差是否超过预设值;若工程车辆在上一次回转设备作业结束后经历了特定行驶过程并且所述回转设备的回转角度与标定的零度回转角之差超过预设值,则生成第一提示信息,提示需要对所述回转设备的回转角度进行重新标定。本申请通过判断工程车辆是否经历特定行驶过程,以及回转设备的回转角度与标定的零度回转角之差是否超过预设值,开展回转角度的重新标定,从而提高标定效率和准确率。
