The invention provides a hydraulic system for counterweight displacement and a crane, and relates to the technical field of cranes, the hydraulic system for counterweight displacement comprises a hydraulic cylinder, a hydraulic power source, an energy accumulator and an adjusting valve bank, a piston rod of the hydraulic cylinder is used for being connected with a counterweight displacement mechanism of the crane, and the piston rod of the hydraulic cylinder is used for being connected with a counterweight displacement mechanism of the crane. The hydraulic power source is connected with the hydraulic cylinder, the adjusting valve group is connected between the hydraulic power source and the hydraulic cylinder so as to adjust stretching and retracting of the hydraulic cylinder, and the energy accumulator is connected with the hydraulic cylinder. By means of the structural arrangement of the hydraulic system, manual balance weight adjustment is replaced, the operation efficiency is high, the situation that a balance weight displacement mechanism and related parts in the crane are possibly damaged due to the adverse operation environment is avoided, and the stability of the overall structure is improved.

    本发明提供了一种用于配重变位的液压系统及起重机,涉及起重机技术领域,所述用于配重变位的液压系统包括液压缸、液压动力源、蓄能器及调节阀组,所述液压缸的活塞杆用于连接所述起重机的配重变位机构,所述液压动力源与液压缸连接,所述调节阀组连接于所述液压动力源与所述液压缸之间,以调节所述液压缸的伸缩,所述蓄能器与所述液压缸连接。本发明通过上述液压系统的结构布置,代替了人工进行调整配重,作业效率高,并且避免了起重机中配重变位机构及其相关部件因不利作业环境可能造成的损坏,提高了整体结构的稳定性。
