The invention relates to the technical field of hoisting equipment, in particular to a self-dismounting-mounting transposition balance weight device and a crane. The self-dismounting-mounting transposition balance weight device comprises a drive mechanism arranged at one of multiple preset positions of a frame of the crane and a balance weight mechanism, wherein the part of the balance weight mechanism is connected with the drive mechanism, and the drive mechanism can drive the balance weight mechanism to move; and when the drive mechanism is arranged at different preset positions, the balanceweight mechanism can be connected with the corresponding installing position of an upper trolley on the crane. According to the provided self-dismounting-mounting transposition balance weight device,other hoisting equipment is not needed, the drive mechanism is used for driving the balance weight mechanism to ascend and descend, the balance weight mechanism is connected to the upper trolley of the crane, then the balance weight mechanism can rotate along with the upper crane, it is ensured that a hoisting arm normally runs, the hoisting arm can have good stability and safety under any rotation radius through selection of different installing positions and corresponding preset positions, and the trolley overturning risk is obviously reduced.
本申请涉及起重设备技术领域,尤其是涉及一种自拆装变位配重装置及起重机,自拆装变位配重装置包括:驱动机构,被安置于起重机的车架的多个预定位置中的其中一个预定位置;配重机构,配重机构的部分与驱动机构相连接,驱动机构能够驱动配重机构运动;驱动机构被安置于不同的预定位置时,配重机构能够与起重机的上车对应的安装位置连接。本申请提供的自拆装变位配重装置,不需要其他起重设备,通过驱动机构驱动配重机构的升降,使配重机构连接至起重机上车,配重机构即可随上车回转,确保起重臂正常运作,并且通过选定不同的安装位置以及对应的预定位置,能够使得起重臂在任一回转半径下均具有较好的稳定性以及安全性,显著降低翻车的风险。
