The invention relates to a floor balance weight device and a telescopic arm crawler crane, the floor balance weight device comprises a lower balance weight, at least two lifting pieces are arranged on the lower balance weight, penetrate through the lower balance weight and are fixedly connected with the bottom of the lower balance weight, and the lifting pieces are uniformly distributed around the center of the lower balance weight; the upper balance weight is arranged above the lower balance weight, the lifting piece penetrates through the upper balance weight, and a first limiting block is arranged above the upper balance weight and used for being matched with a rotary table; a limiting assembly is arranged between the upper balance weight and the lower balance weight and used for limiting linear displacement between the upper balance weight and the lower balance weight in the horizontal plane direction. According to the floor balance weight device and the telescopic arm crawler crane, a supporting component below the balance weight device is omitted, quick centering can be achieved, overall hoisting can be achieved, and the transition efficiency of the telescopic arm crawler crane is improved.

    本发明涉及到一种落地配重装置及伸缩臂履带起重机,所述落地配重装置包括:下配重,所述下配重上设有提升件,且所述提升件贯穿所述下配重,与所述下配重的底部固定连接,所述提升件至少设有两个,绕所述下配重的中心均布;上配重,排列设置于所述下配重的上方,所述提升件贯穿所述上配重,所述上配重上方设有第一限位块,用于与转台匹配;所述上配重与所述下配重之间设有限位组件,所述限位组件用于限制所述上配重与所述下配重之间沿水平面方向的线性位移。本申请提供的落地配重装置及伸缩臂履带起重机,省掉配重装置下方的支撑部件,能快速对中,且能整体吊装,提高伸缩臂履带起重机转场效率。
