The invention provides a crawler telescopic boom crane and a control method thereof. The crawler telescopic boom crane comprises a hoisting mechanism, a connecting arm mechanism and a balance weight trolley, the hoisting mechanism comprises a hoisting chassis, a slewing bearing arranged on the hoisting chassis and an upper part hinged to the slewing bearing, the balance weight trolley is provided with a balance weight chassis, one end of the connecting arm mechanism is hinged to the slewing bearing, and the other end of the connecting arm mechanism is hinged to the upper part of the slewing bearing. The other end of the lifting rod is hinged with the counterweight trolley; when the counterweight chassis does circular motion along the hoisting mechanism, the slewing bearing and the upper part on the slewing bearing are driven to rotate through the connecting arm mechanism; and when the counterweight chassis is parallel to the hoisting chassis, the crawler telescopic boom crane is in a walking or to-be-walking state. According to the invention, large-load far-amplitude hoisting operation can be realized, actions such as on-load walking and rotation can be realized, and the hoisting construction requirements are met.

    本发明提供一种履带伸缩臂起重机及其控制方法。所述履带伸缩臂起重机包括起重机构、连接臂机构和配重小车,所述起重机构包括起重底盘、设于所述起重底盘上的回转支承、及铰接于所述回转支承上的上装,所述配重小车设有配重底盘,所述连接臂机构的一端与所述回转支承铰接,另一端与所述配重小车铰接;所述配重底盘沿所述起重机构做圆周运动时,通过所述连接臂机构驱动所述回转支承及其上的上装回转;所述配重底盘与起重底盘平行时,所述履带伸缩臂起重机处于行走或待行走状态。本发明可实现大载荷远幅度的吊装作业,同时可带载行走、回转等动作,满足吊装施工要求。
