The invention relates to a crane capable of adjusting a counterweight position. The crane comprises a crane main body, a counterweight, and a telescopic driving device; the counterweight is connectedwith the crane main body through a parallelogram mechanism; the parallelogram mechanism comprises two parallel connecting arms with the same length; the top ends of the connecting arms are hinged to the crane main body, and the bottom ends of the connecting arms are hinged to the counterweight; and one end of the telescopic driving device is hinged to the crane main body, and the other end of thetelescopic driving device is hinged to the counterweight, so that when the telescopic driving device stretches out and draws back, the relative position of the counterweight and the crane main body isadjusted. The counterweight and the crane main body are connected through the connecting arms hinged to the counterweight and the crane main body respectively, and the counterweight is driven to moverelative to the crane main body through the stretching and the retracting of the telescopic driving device, so that the operation is easy, and the adjustment of the counterweight can be easily achieved.

    本发明涉及一种可调节配重位置的起重机,包括起重机主体和配重,配重与起重机主体之间通过平行四边形机构连接;平行四边形机构包括两只平行且长度相等的连接臂,所述连接臂的顶端铰接在起重机主体上,底端铰接在配重上,还包括伸缩驱动装置,伸缩驱动装置的一端铰接在重机主体上,另一端铰接在配重上,以在伸缩驱动装置伸缩时调整配重与起重机主体的相对位置。配重与起重机主体通过分别与配重和起重机主体铰接的连接臂连接,并通过伸缩驱动装置伸缩,带动配重相对于起重机主体运动,操作简单,能够轻易的实现对配重的调节。
