The invention discloses a mast auxiliary pulling rod system and method and a crane, the system comprises a crane host unit, a mast amplitude changing device, a jacking pulling rod device and an auxiliary pulling rod device, the jacking pulling rod device is used for jacking and pulling the mast amplitude changing device, and the auxiliary pulling rod device comprises an auxiliary support, a telescopic driving part and a self-loading and unloading lifting appliance; the auxiliary support is arranged on the crane main machine unit and located on the front side of the mast luffing device, the telescopic driving piece is arranged at the upper end of the mast luffing device, and the two ends of the self-loading and unloading lifting appliance are connected with the telescopic end of the telescopic driving piece and the auxiliary support in a one-to-one correspondence mode respectively. The mast amplitude changing device can be lifted and pulled in an auxiliary mode under the condition that the telescopic end of the telescopic driving part retracts, so that the rod pulling operation of the reinforced and lengthened mast amplitude changing device can be completed, and then the reinforced and lengthened mast amplitude changing device can meet the arm lifting requirement of a long and heavy arm frame. The purposes of simplifying the installation process of the mast system and reducing the transportation workload are achieved.

    本发明公开一种桅杆辅助扳杆系统、方法及起重机,系统包括起重机主机单元、桅杆变幅装置、顶升扳杆装置和辅助扳杆装置,顶升扳杆装置用于顶升扳动桅杆变幅装置,辅助扳杆装置包括辅助支架、伸缩驱动件和自装卸吊具,辅助支架设于起重机主机单元上并位于桅杆变幅装置的前侧,伸缩驱动件设于桅杆变幅装置的上端,自装卸吊具的两端分别一一对应地与伸缩驱动件的伸缩端和辅助支架连接,以能够在伸缩驱动件的伸缩端进行缩回运动的情况下辅助拉升扳动桅杆变幅装置,从而可以完成加强加长的桅杆变幅装置的扳杆操作,进而使得加强加长的桅杆变幅装置能够满足较长较重臂架的起臂要求,达到了简化桅杆系统的安装过程以及降低运输工作量的目的。
