The invention discloses a crane capable of preventing overturning and achieving automatic protection. The crane comprises a crane body, hydraulic supporting rods capable of sliding up and down are symmetrically arranged at the left side and the right side in the crane body, a fixing piece is fixedly connected to the left end face of the crane body, and a connecting rod capable of sliding up and down is arranged in the fixing piece; and a connecting rod base is in hinge connection to the lower end of the connecting rod, when the crane body overturns with the hydraulic supporting rod at the left side as the fulcrum, the crane body is prevented from being damaged due to overturning through a manner of supporting the crane body through a supporting rod, then the crane body is protected through a manner that a hanging piece is disconnected from the crane body, the loss is reduced, meanwhile, workers can be prevented from being injured, finally, shock absorption is conducted through shock absorption supporting rods, damage to the crane body during resetting of the crane body is prevented, and the maintenance cost is reduced.

    本发明公开的一种能防止翻倒并自动保护的起重机,包括起重机主体,所述起重机主体内左右两侧对称设有能上下滑动的液压支撑杆,所述起重机主体左端面固定连接有固定件,所述固定件内设有能上下滑动的连杆,所述连杆下端铰链连接有连杆底座,当所述起重机主体以左侧所述液压支撑杆为支点进行翻转时,本发明先通过支撑杆对起重机主体进行支撑的方式,防止起重机主体进行翻转,造成损坏,再通过悬挂件与起重机主体脱离连接的方式,对起重机主体进行保护,减少损失,同时能防止工作人员受到伤害,最后通过减震支撑杆进行减震,防止起重机主体复位时对其自身造成的损伤,降低了维修成本。
