The invention relates to a crane control method and device, a crane and a computer readable storage medium, and relates to the field of crane control. The control method of the crane comprises the steps that under the condition that the crane tends to overturn, a hydraulic power system of the crane stops supplying oil to an execution element of a hoisting mechanism of the crane, so that the execution element is controlled through a closed loop formed by the execution element in an oil way and a control system; opening a normally closed brake of the hoisting mechanism; according to the state of the crane, the load of the hoisting mechanism and the stability requirement, target pulling force provided by the hoisting mechanism for the load is determined; and controlling the execution element to enable the hoisting mechanism to provide the target pulling force. According to the invention, safe and rapid unloading can be realized under the condition that the crane tends to overturn, so that the crane returns to a stable state again, and more serious safety accidents caused by overturning of the crane are prevented.

    本公开涉及一种起重机的控制方法、装置、起重机和计算机可读存储介质,涉及起重机控制领域。起重机的控制方法包括:在起重机产生倾覆趋势的情况下,停止起重机的液压动力系统向起重机的起升机构的执行元件供油,以通过油路中执行元件及控制系统形成的闭式回路控制执行元件;打开起升机构的常闭式制动器;根据起重机的状态、起升机构的载荷以及稳定性要求,确定起升机构向所述载荷提供的目标拉力;控制执行元件以使起升机构提供目标拉力。本公开能够在起重机产生倾覆趋势的情况下,实现安全快速卸载,使起重机重新回到稳定状态,防止因起重机倾覆而造成更严重的安全事故。
