The invention relates to the technical field of hoisting, in particular to a crane with an overload locking device, which comprises a tower body, a rotary arm, a hoisting mechanism and a trigger device, and the hoisting mechanism and the trigger device are respectively arranged on two side arms of the rotary arm; the trigger device comprises a load torque module and a counterweight torque module, and the counterweight torque module is used for converting the gravity of the counterweight block and then outputting the gravity in a rotating form; the load torque module integrates the gravity of the heavy object and the distance between the heavy object and the tower body, outputs the gravity in a rotating mode, compares the gravity with the rotating amplitude output by the counterweight torque module, judges whether the torque of the heavy object exceeds the counterweight torque of the counterweight block or not, and if the torque of the heavy object exceeds the counterweight torque of the counterweight block, the hoisting mechanism is locked and stopped in time. And the device is prevented from being damaged. The weight of the heavy object and the distance between the heavy object and the tower body are comprehensively considered, and whether overload occurs or not is judged more accurately according to the result.

    本发明涉及起吊技术领域,具体涉及一种具有过载锁定装置的起重机,包括塔身、回转臂、卷扬机构和触发装置,卷扬机构和触发装置分别安装于回转臂的两侧臂;触发装置包括负载力矩模块和配重力矩模块,配重力矩模块用于将配重块的重力转化后以转动的形式输出;负载力矩模块将重物的重力和与塔身的距离整合后以转动的形式输出,并与配重力矩模块输出的转幅对比,判断重物的力矩是否大于超出了配重块的配重力矩,若重物的力矩超出配重块的配重力矩,则使卷扬机构及时锁定停止,避免造成装置损坏。综合考虑重物的重量以及重物与塔身的距离,以此为结果判断其是否过载更为准确。
