The invention relates to a crane structure improvement technology, and discloses an anti-shake hoisting device for a crane, which is characterized in that a hoisting rope limiting mechanism is movably mounted at one end of a pulley assembly, and the whole hoisting rope limiting mechanism is jointly formed by a U-shaped frame, a guide pipe, a damper and a clamping assembly; the characteristic that the guide pipe is connected with the damper is utilized to effectively limit the swing amplitude of the whole lifting rope limiting structure, meanwhile, through cooperation of the guide pipe and the clamping assembly, the lifting rope limiting structure is clamped and fixed through power generated when the lifting hook ascends, and therefore the situation that the lifting hook shakes due to stormy waves under the non-lifting condition is avoided, and potential safety hazards are reduced.
本发明涉及起重机结构改进技术,本发明公开了一种用于起重机的防晃吊装装置,其在滑轮组件的一端活动安装吊绳限制机构,整个吊绳限制机构采用U形框、导向管和阻尼器和夹紧组件共同构成,利用导向管与阻尼器相互连接的特点有效的限制整个吊绳限制结构的摆动幅度,同时通过导向管与夹紧组件的配合,利用吊钩上升时的动力对其进行加紧固定,从而避免吊钩在非吊装情况下因风浪产生晃动,降低安全隐患。
