The crane comprises a large lifting hook, a small lifting hook, a first winch, a second winch, a second handle and a first handle, the first winch controls the large lifting hook to ascend and descend, the second winch controls the small lifting hook to ascend and descend, and the second handle controls the small lifting hook to ascend and descend. The crane double-hook working condition switching method comprises the following steps: acquiring a handle state signal, and sending the handle state signal to a judgment module; determining to-be-executed hoisting work according to the handle state signal; the lifting hook working condition information corresponding to the to-be-executed lifting industry is sent to the force limiter; the force limiter receives the working condition of the corresponding lifting hook and performs hoisting performance calculation; and the controller logically judges whether safety exists or not, and if yes, the hoisting work to be executed is executed. When an operator operates the handle, working condition judgment and working condition data sending can be automatically carried out, the purpose of freely switching the working conditions of the large hook and the small hook for hoisting is achieved, the operation steps of a driver during operation are reduced, the workload is reduced, and operation is more intelligent and humanized.

    本发明公开了一种起重机双钩工况切换方法及起重机,所述起重机包括大吊钩、小吊钩、第一卷扬、第二卷扬、第二手柄和第一手柄,第一卷扬控制大吊钩的升降,第二卷扬控制小吊钩的升降,所述起重机双钩工况切换方法包括以下步骤:获取手柄状态信号,将其发送至判断模块;根据手柄状态信号确定待执行吊业;将待执行吊业对应的吊钩工况信息发送至力限器;力限器接收对应吊钩工况,进行吊重性能计算;控制器进行逻辑判断是否安全,若安全,则执行该待执行吊业。本发明使得作业者在操作手柄时,可以自动进行工况判断及工况数据发送,达到自由切换大小钩工况进行吊重的目的,减少了司机在作业时的操作步骤,减少工作量,使得操作更加智能化、人性化。
