The invention discloses a lifting appliance capable of adjusting the position of a hanging point and the inclination angle of a lifted object and an operation method of the lifting appliance. The lifting appliance comprises a hanging connecting part, a hanging point offsetting assembly, a transverse swinging assembly, longitudinal swinging and tensioning assemblies and a hydraulic control system;the hanging connecting part is connected to the hanging point offsetting assembly; the hanging point offsetting assembly and the transverse swinging assembly are connected to the longitudinal swingingand tensioning assemblies; the two longitudinal swinging and tensioning assemblies are connected to the two ends of the transverse swinging assembly through pin shafts and can rotate along the longitudinal direction of the lifting appliance; and the hydraulic control system is installed on the transverse swinging assembly and connected with each control oil cylinder in the hanging point offsetting assembly, the transverse swinging assembly and the longitudinal swinging and tensioning assemblies. The lifting appliance is compact in structure and safe and reliable to use; the lifting applianceis tightly frapped with a segment box girder and achieves slop adjustment by using a layered hinged and hydraulic/mechanical locked tensioning mechanism; a hydraulic adjusting mechanism is adopted, sothat the lifting point transversely moves in a stepwise and stepless manner so as to adapt to the change of the gravity center positions of segmental box girders with different configurations; and the operation method is simple and convenient to implement, and the operation can be safely and reliably completed.

    可调节吊挂点位置和被吊物体倾斜角度的吊具及操作方法,包括:吊挂连接件、挂点偏移总成、横摆总成、纵摆与张紧总成、液压控制系统;吊挂连接件连接在挂点偏移总成上,挂点偏移总成与横摆总成连接在纵摆与张紧总成上,两套纵摆与张紧总成通过销轴连接在横摆总成的两端,能够沿着吊具的纵向转动,液压控制系统安装在横摆总成上,并与挂点偏移总成、横摆总成、纵摆与张紧总成中的各个操纵油缸相连接。本吊具结构紧凑、使用安全可靠。其利用分层的铰接和液/机锁定的张紧机构使吊具与节段箱梁紧缚并实现坡度调整;采用液压调节机构,使起吊点可以分段无级横移以适应节段箱梁不同构型的重心位置变化,操作方法简便,可以安全可靠地完成操作。
