The invention relates to a crane and a crane control method. The crane comprises a bearing part, a cargo boom, a lifting hook, a winch system, a positioning system and a controller. The cargo boom is mounted on the bearing component in a pitching swinging manner and comprises a boom head positioned at one end, far away from the bearing part, of the cargo boom. The lifting hook is hung on the boom head of the cargo boom. The winch system is mounted on the bearing part and is configured to drive the lifting hook to lift. The positioning system comprises a first positioning part mounted on the lifting hook so as to detect the position of the lifting hook in the three-dimensional coordinate system. The controller is in signal connection with the winch system and the positioning system and is configured to control the winch system to act according to the position change of the first positioning part so as to adjust the lifting hook to a preset position. The problem of low precision caused by structural deformation of a frame, the cargo boom, a superlift and the like when the position of the lifting hook is calculated by utilizing the length and the pitching angle of the cargo boom in the related technology is solved.

    本发明涉及一种起重机和起重机的控制方法,起重机包括:承载部件;起重臂,可俯仰摆动地安装在承载部件上且包括位于其远离承载部件的一端的臂头;吊钩,悬挂在起重臂的臂头上;卷扬系统,安装在承载部件上并被配置成驱动吊钩升降;定位系统,包括安装在吊钩上的第一定位部件,以检测吊钩在三维坐标系中的位置;以及控制器,与卷扬系统和定位系统分别信号连接,并被配置成根据第一定位部件的位置变化控制卷扬系统动作以将吊钩调整至预设位置,改善了相关技术中利用起重臂的臂长和俯仰角度来计算吊钩的位置时因车架、起重臂、超起等发生结构变形而带来的精度低的问题。
