The invention provides a luffing system of a tower crane and the crane. The luffing system of the tower crane comprises a luffing rope winding mechanism and a luffing vehicle group, the variable-amplitude rope winding mechanism comprises a fixedly arranged variable-amplitude winding drum and a variable-amplitude rope wound on the variable-amplitude winding drum; the variable-amplitude trolley group comprises a first variable-amplitude trolley and a second variable-amplitude trolley which can walk along a cargo boom of the tower crane, and a connecting frame of which the two ends are detachably connected with the first variable-amplitude trolley and the second variable-amplitude trolley; wherein the connecting frame is connected with the two ends of the variable-amplitude rope, so that the first variable-amplitude trolley and the second variable-amplitude trolley can synchronously change the amplitude or independently change the amplitude. According to the technical scheme, synchronous amplitude variation and independent amplitude variation of the first amplitude variation trolley and the second amplitude variation trolley can be achieved at the same time through one amplitude variation rope winding mechanism, so that the purpose of improving the universality of the crane is achieved.

    本发明提供一种塔机的变幅系统及起重机,塔机的变幅系统包括:变幅绕绳机构和变幅车组;变幅绕绳机构包括固定设置的变幅卷筒以及卷设于变幅卷筒上的变幅绳;变幅车组包括能够沿塔机的起重臂行走的第一变幅小车和第二变幅小车,以及两端可拆卸地连接第一变幅小车和第二变幅小车的连接架;其中,连接架与变幅绳的两端相连,使得第一变幅小车和第二变幅小车能够同步变幅或独立变幅。通过本发明的技术方案,可以通过一套变幅绕绳机构同时实现第一变幅小车和第二变幅小车的同步变幅和独立变幅,以达到提高起重机的通用性的目的。
