The invention discloses an engineering machinery maintenance hoisting crane, which belongs to the technical field of cranes, and comprises a mounting unit, a crane body, a hydraulic cylinder body arranged at the rear part of the upper end of the crane body, an adjusting assembly arranged in the hydraulic cylinder body, and a hoisting assembly arranged on the adjusting assembly; and the control unit comprises a control assembly arranged below the hoisting assembly. According to the lifting crane for engineering machinery maintenance, the ejector rod extends outwards to be in contact with one side of the lifting rope, and an acting force for outward movement is applied, so that the lifting rope is bent, and the height of one hanging point is different from that of other hanging points, so that the effect of forming a required inclined posture after machinery is lifted is achieved; the relative position of the ejector rod in the lower pressing disc is controlled by controlling the rotating rod, and then whether the extrusion block can make contact with the ejector rod or not is controlled, so that the effect that the ejector rod at the designated position exerts acting force on the lifting rope, and the lifted mechanical part forms the needed posture is achieved.

    本发明公开了一种工程机械维修吊运起重机,属于起重机的技术领域,包括安装单元,包括起重机本体、设置于所述起重机本体上端后部的液压缸体、设置于所述液压缸体内部的调节组件,以及设置于所述调节组件上的起重组件;控制单元,包括设置于所述起重组件下的控制组件。该工程机械维修吊运起重机能通过顶杆向外伸出与吊绳的一侧接触,并施加向外移动的作用力,让吊绳产生弯折,使得其中一个挂点的高度区别于其他挂点,从而达到使机械吊起后形成所需倾斜姿态的效果,通过控制转杆控制顶杆在下压盘内的相对位置,进而控制挤压块能否与顶杆接触,从而达到让指定位置的顶杆对吊绳施加作用力,使得吊起的机械部件形成所需姿态的效果。
