The invention relates to a hoisting device with a floor double-rocker-arm derrick additionally provided with a herringbone auxiliary derrick, and belongs to the technical field of hoisting. The hoisting device with the floor double-rocker-arm derrick additionally provided with the herringbone auxiliary derrick comprises an iron tower cross arm, a mast and rocker arms rotationally arranged on the two opposite sides of the mast, and further comprises herringbone derrick single bodies arranged on the two opposite sides of the iron tower cross arm; the two rocker arms are located between the two herringbone derrick single bodies, the herringbone derrick single bodies are located below the rocker arms, the distances from the herringbone derrick single bodies to the mast are sequentially increased from bottom to top, and the distance from the end, away from an iron tower cross arm, of each herringbone derrick single body to the mast is larger than the distance from the end, away from the mast, of the iron tower cross arm to the mast. The lifting device has the effects that the lifting range is expanded, and tower materials above the iron tower cross arm can be conveniently lifted under the condition that the length of the iron tower cross arm exceeds the lifting range of the rocker arm.
本申请涉及一种落地双摇臂抱杆加装人字辅助抱杆的吊装装置,属于吊装技术领域,落地双摇臂抱杆加装人字辅助抱杆的吊装装置包括铁塔横担、桅杆和转动设置在桅杆相对两侧的摇臂,还包括设置在铁塔横担相对两侧的人字抱杆单体,两个所述摇臂位于两个人字抱杆单体之间,所述人字抱杆单体位于摇臂下方,所述人字抱杆单体至桅杆的距离从下至上依次增大,所述人字抱杆单体远离铁塔横担的一端至桅杆的距离大于铁塔横担远离桅杆的一端至桅杆的距离。本申请具有扩大吊装范围,方便在铁塔横担长度超出摇臂吊装范围的情况下对铁塔横担以上的塔材进行吊装的效果。
