According to the crane boom, one end of a first limb rod and one end of a second limb rod are hinged to a rotary table, and the other end of the first limb rod makes contact with the other end of thesecond limb rod. A first lifting hook group is arranged at the other end of the first limb rod, and a second lifting hook group is arranged at the other end of the second limb rod. A first variable-amplitude winding mechanism bypasses the top end of a propeller strut, and the two ends of the first variable-amplitude winding mechanism are connected with a first variable-amplitude winch and the other end of the first limb rod respectively and used for driving the first limb rod to rotate around a hinge point in a variable-amplitude mode; a second variable-amplitude winding mechanism bypasses thetop end of the propeller strut, and the two ends of the second variable-amplitude winding mechanism are connected with a second variable-amplitude winch and the other end of the second limb rod correspondingly and used for driving the second limb rod to rotate around the hinge point in a variable-amplitude mode; a first hoisting winding mechanism bypasses the top end of the propeller strut, and two ends of the first hoisting winding mechanism are respectively connected with a first hoisting winch and the first lifting hook group and used for driving the first lifting hook group to lift; and asecond hoisting winding mechanism bypasses the top end of the propeller strut, and two ends of the second hoisting winding mechanism are respectively connected with the first hoisting winch and the second lifting hook group and used for driving the second lifting hook group to lift.

    本发明公开了一种起重机臂架,其中,第一肢杆和第二肢杆的一端分别铰接在转台上,第一肢杆和第二肢杆的另一端接触;第一吊钩组设置在第一肢杆的另一端,第二吊钩组设置在第二肢杆的另一端;第一变幅缠绕机构绕过人字架的顶端,两端分别与第一变幅绞车和第一肢杆的另一端连接,用于驱动第一肢杆绕铰接点变幅转动;第二变幅缠绕机构绕过人字架的顶端,两端分别与第二变幅绞车和第二肢杆的另一端连接,用于驱动第二肢杆绕铰接点变幅转动;第一起升缠绕机构绕过人字架的顶端,两端分别与第一起升绞车和第一吊钩组连接,用于驱动第一吊钩组升降;第二起升缠绕机构绕过人字架的顶端,两端分别与第一起升绞车和第二吊钩组连接,用于驱动第二吊钩组升降。
