The invention discloses a counterweight system of a fixed crane and the fixed crane. The counterweight system comprises a rotary walking track and a counterweight assembly, and the rotary walking track is arranged on the upper portion of the supporting plate and comprises a first track and a second track; the balance weight assembly comprises a balance weight rope, a gravity body, connecting frames, a rotary driving device and a rotary walking mechanism, the balance weight rope is connected between the upper portion of the gravity body and the tail of the rotary table, the two connecting frames are symmetrically fixed to the two sides of the bottom of the gravity body, the rotary walking mechanism is arranged on the connecting frames, and the rotary driving device is connected to the rotary walking mechanism; the rotary walking mechanism comprises a first walking wheel and a second walking wheel, and the first walking wheel and the second walking wheel are installed on the first track and the second track respectively. The bending moment borne by the stand column is greatly reduced, the section of the stand column and the length of the supporting rod can be reduced, the self weight of equipment is remarkably reduced, meanwhile, the gravity center height of the whole machine is greatly reduced, and the overturning stability of the whole machine is effectively improved.
本发明公开了一种固定式起重机的配重系统及固定式起重机。配重系统包括回转行走轨道和配重组件,回转行走轨道设置在支撑板上部,包括第一轨道和第二轨道;配重组件包括配重绳、重力体、连接架、回转驱动装置、回转行走机构,配重绳连接在重力体的上部以及转台的尾部之间,重力体的底部两侧对称固定有两个连接架,回转行走机构设置在连接架上,回转驱动装置连接于回转行走机构;回转行走机构包括第一行走轮和第二行走轮,第一行走轮和第二行走轮分别安装在第一轨道和第二轨道上。本发明使得立柱承受的弯矩大幅降低,可减小立柱的截面以及缩短支撑杆的长度,显著降低设备自重,同时整机重心高度大幅度降低,有效提高了整机倾覆稳定性。
