The invention provides an eccentric hoisting method, an eccentric hoisting device and an eccentric hoisting system. The eccentric hoisting method comprises the following steps: a determination step: determining the number of hoists to be three; setting and measuring: setting a first lifting hook and a second lifting hook to be positioned on one side of the steel structural member and a third lifting hook to be positioned on the other side of the steel structural member; the distance between the first lifting hook and the center line of the crane is measured as l4, the distance between the second lifting hook and the center line of the crane is measured as l3, and l4 is equal to l3; measuring the distance L4 from the gravity center line of the steel structural member to the first lifting hook in the first direction, and measuring the distance L3 from the gravity center line of the steel structural member to the second lifting hook in the first direction; a judgment step: judging if L4gt; l4 or L3gt; l3; and a calculation step: calculating the stress of the first lifting hook, the stress of the second lifting hook and the stress of the third lifting hook. The steel structural part can be smoothly hoisted when the distance between the center line of the crane and the gravity center line of the steel structural part has a certain deviation.
本申请提供了偏心吊装方法、偏心吊装装置以及偏心吊装系统,偏心吊装方法包括以下步骤:确定步骤:确定吊马的数量为三个;设定、测量步骤:设定第一吊钩与第二吊钩位于钢结构件的一侧,第三吊钩位于钢结构件的另一侧;测量第一吊钩到吊车的中心线的距离为l4,测量第二吊钩到吊车的中心线的距离为l3,且l4=l3;测量钢结构件的重心线到第一吊钩在第一方向上的距离为L4,测量钢结构件的重心线到第二吊钩在第一方向上的距离为L3;判断步骤:如果L4>l4或L3>l3;计算步骤:计算第一吊钩的受力、第二吊钩的受力以及所述第三吊钩的受力。本申请能够在吊车的中心线与钢结构件的重心线的距离有一定偏差,实现钢结构件的顺利吊装。
