The invention provides a crane, a steel wire rope pre-tightening device and method thereof, electronic equipment and a storage medium. The steel wire rope pre-tightening device for the crane comprises a lifting mechanism, a steel wire rope, an arm head pulley assembly, a lifting hook pulley assembly, a pre-tightening mechanism and a holding member, and the arm head pulley assembly is mounted at the top end of a cargo boom of the crane; the lifting hook pulley assembly is connected with the arm head pulley assembly through steel wire ropes; the pre-tightening mechanism is fixedly connected with the free ends of the steel wire ropes penetrating through the arm head pulley assembly and the lifting hook pulley assembly, and the steel wire ropes can be sequentially arranged on the outer side of the pre-tightening mechanism; and the holding member that can hold the hook pulley assembly relative to the ground. The winding and unwinding of the two ends of the steel wire ropes are adjusted in a matched mode through the pre-tightening mechanism and the lifting mechanism, pre-tightening is completed after the steel wire ropes hook a heavy object and before the heavy object is lifted, it is guaranteed that when the lifting mechanism winds and unwinds the steel wire rope, the steel wire ropes are in a tensioned state, the rope disorder phenomenon is avoided, and meanwhile, energy consumption is reduced.

    本发明提供的起重机及其钢丝绳预紧装置、方法、电子设备、存储介质。该起重机用钢丝绳预紧装置包括提升机构和钢丝绳,还包括臂头滑轮组件,安装在起重机的起重臂顶端;吊钩滑轮组件,与臂头滑轮组件通过钢丝绳连接;预紧机构,与穿设过臂头滑轮组件、吊钩滑轮组件后的钢丝绳的自由端固定连接,且钢丝绳可被依次按序排列在预紧机构的外侧;保持部件,可相对地面保持吊钩滑轮组件。本发明通过预紧机构和提升机构对钢丝绳的两端的卷收和放送配合调整,实现对钢丝绳在钩挂重物后,吊起重物之前,完成预紧,保证提升机构对钢丝绳进行卷收和放送时,钢丝绳处于张紧状态,不会出现乱绳现象,同时,节约能耗。
