The embodiment of the invention provides a counterweight device and a crane. The counterweight device comprises a counterweight assembly and a supporting assembly, wherein the counterweight assembly is connected with a rotary platform of the crane; one end of the supporting assembly is connected onto the counterweight assembly or the rotary platform; and the other end of the supporting assembly is supported on the ground. Through the structural arrangement, the supporting assembly can form supporting between the counterweight assembly and the ground or between the rotary platform and the ground. Therefore, the whole crane can be effectively prevented from tilting backwards, and the stability of the crane is greatly improved. Furthermore, the phenomenon that the rotary platform and a slewing bearing are damaged due to the fact that the whole machine tilts backwards is effectively prevented.

    本发明实施例提供了一种配重装置及起重机。其中,配重装置包括:配重组件和支撑组件。其中,所述配重组件与起重机的回转平台连接,所述支撑组件的一端连接于所述配重组件或者所述回转平台上,所述支撑组件的另一端支撑于地面。通过这种结构设置,所述支撑组件能够在所述配重组件与地面之间、或者在所述回转平台与地面之间形成支撑。由此,能够有效防止起重机整机发生后倾现象,极大提升了起重机的稳定性。进而,有效防止了由于整机后倾所导致的破坏所述回转平台和所述回转支承的现象发生。
