The invention relates to the technical field of hoisting equipment, in particular to a reliable crane. According to the technical scheme, the crane comprises a crane body and further comprises a balancing weight arranged on the lower side of the crane body, a concentric-square-shaped groove is formed in the outer side wall of the balancing weight, external connection mechanisms capable of rotating towards the outer side are arranged at the four corners of the concentric-square-shaped groove, and a driving mechanism for driving the four external connection mechanisms to rotate synchronously is arranged in the concentric-square-shaped groove; the external connection mechanism comprises a rotating rod rotationally installed in the concentric-square-shaped groove, a hydraulic telescopic rod capable of stretching out and drawing back is fixed to the outer side of the rotating rod, and an installation through hole is formed in the tail end of the hydraulic telescopic rod. The driving mechanism is operated to enable the four external connection mechanisms to rotate to the outer side, then the supporting mechanisms are assembled to the tail ends of the external connection mechanisms, meanwhile, the supporting pieces support the external connection mechanisms, the flexible plates incline towards the outer side, barb structures are formed, the firmness with the land is improved, and then the overall stability and reliability can be improved.
本发明涉及吊装设备技术领域,尤其涉及一种可靠型起重机。其技术方案包括:包括起重机主体,还包括设置于起重机主体下侧的配重块,所述配重块的外侧壁开设有回形槽,所述回形槽的四角处均设置有可向外侧转动的外接机构,所述回形槽内设置有驱动四个外接机构同步转动的驱动机构;所述外接机构包括转动安装于回形槽内的转动杆,所述转动杆的外侧固定有可进行伸缩的液压伸缩杆,所述液压伸缩杆的末端开设有安装通孔。本发明运行驱动机构使得四个外接机构均转动至外侧,再将支撑机构组装至外接机构末端,同时支撑件对外接机构进行支撑,软性板向外侧倾斜,形成倒刺结构,增加了与土地的牢固形,进而可增加整体的稳定性以及可靠性。
