The invention relates to the technical field of hoisting construction. The lifting appliance is used for connecting lifting equipment and an object to be lifted and comprises a main beam and a plurality of auxiliary beams. The main beam is used for being connected with hoisting equipment, all the auxiliary beams are arranged on the main beam at intervals, and any two adjacent auxiliary beams can be close to or away from each other. And a plurality of telescopic first slings are arranged on each secondary beam at intervals. During use, the main beam is connected to a lifting hook of lifting equipment, then the position of the gravity center of a to-be-lifted object is obtained according to the structure of the to-be-lifted object, the position of a lifting lug on the to-be-lifted object is determined, and then the appropriate first sling on the auxiliary beam is selected to be connected with the lifting lug on the to-be-lifted object. And after the connection is completed, the operator tries to lift the object to be lifted according to the length of the first sling, so that the lifting hook of the lifting equipment and the calculated gravity center of the object to be lifted are located on the same vertical line. Compared with the prior art, a lifting appliance does not need to be designed before lifting operation, and the construction cost is reduced.

    本发明提供了一种,涉及起重施工的技术领域。本发明的吊具,用于连接起重设备与待起重物体,包括:主梁和多个副梁。主梁用于与起重设备连接,全部副梁间隔设置于主梁上,且任意相邻的两个副梁能够相互靠近或者远离。每个副梁上均间隔设置有多个可伸缩的第一吊索。使用时,将主梁连接于起重设备的吊钩上,之后根据待起重物体的结构,得出待起重物体计算重心的位置,以及确定待起重物体上吊耳的位置,之后,选取副梁上合适的第一吊索与待起重物体上的吊耳相连。连接完成后,操作人员通过对待起重物体试吊并第一吊索的长度,以使起重设备的吊钩和待起重物体的计算重心位于同一垂直线上。相比于现有技术,无需在吊装作业前设计吊具,降低施工成本。
