The invention discloses a novel crane which is provided with a truss arm frame and a box type telescopic arm frame, and the box type telescopic arm frame serves as a mast. A winch system of the crane comprises a first lifting winch, a variable-amplitude winch and a second lifting winch, a steel wire rope led out of the first lifting winch goes to the top of the truss arm frame and winds a main lifting hook to serve as a main hoisting system, and a steel wire rope led out of the second lifting winch goes to the top of the box type telescopic arm frame and winds a main lifting hook to serve as a main hoisting system. And the auxiliary hoisting system is used as an auxiliary hoisting system. According to the invention, a truss arm crane and a telescopic arm crane (box type) are integrated, different engineering requirements can be met, and meanwhile, one product can be used as the truss arm crane as required, can also be used as the telescopic arm crane, and can also have the hoisting functions of the truss arm crane and the telescopic arm crane at the same time; the arm raising capability of the whole machine is improved, namely the arm of force during arm raising is increased; the equipment utilization rate of crane users is improved, and the purchase and operation cost is reduced.
本发明公开了一种新型起重机,起重机设有桁架臂臂架与箱型伸缩臂架,箱型伸缩臂架作为桅杆;起重机的卷扬系统包括第一起升卷扬、变幅卷扬与第二起升卷扬,从第一起升卷扬引出的钢丝绳走向桁架臂臂架顶部,缠绕主吊钩作为主吊重系统使用,从第二起升卷扬引出的钢丝绳走向箱型伸缩臂架顶部,缠绕于副吊钩作为副吊重系统使用。本发明融合了桁架臂起重机和伸缩臂起重机(箱型),可以适应不同的工程需要,同时一台产品可以根据需要作为桁架臂起重机使用,也可以作为伸缩臂起重机,还可以同时具有桁架臂起重机和伸缩臂起重机的吊装功能;提高整机的起臂能力,即增加起臂时的力臂;提高起重机用户的设备利用率,降低采购运营成本。
