The invention discloses a balance weight system for a crane and the crane, and belongs to the technical field of crane balance weights. The balance weight system involves a supporting frame; the bottom end of the supporting frame is fixedly arranged on a rotary table, and the top end of the supporting frame is connected with a mast connected to the rotary table through a mast luffing mechanism; and the top end of the supporting frame is connected with a set of balance weights through a balance weight connecting mechanism, and the balance weights are connected to the tail portion of the rotarytable through a balance weight luffing mechanism. According to the system, the stress state of the rotary table, the mast and a slewing bearing can be improved, and the arm lifting capacity and the hoisting capacity of the crane are enhanced.

    本发明公开了一种用于起重机的平衡重系统和起重机,属于起重机平衡重技术领域,所述平衡重系统包括支撑架;所述支撑架的底端固定设置于转台上,所述支撑架的顶端通过桅杆变幅机构与连接于转台上的桅杆相连接;所述支撑架的顶端还通过平衡重连接机构与一组平衡重相连接,所述平衡重通过平衡重变幅机构连接于所述转台尾部。本发明能够改善转台、桅杆和回转支承的受力状态,增强起重机的起臂能力和吊重能力。
