The invention relates to a using method of a lifting appliance, the lifting appliance and a crane. The using method comprises the following steps: at least two clamping arms are connected with a counterweight base to form a clamp; the lifting rod is in sliding connection with the counterweight base, and a sliding shaft of the lifting rod and the counterweight base is a shaft B; the counterweight base, the clamping arm, the transmission device and the lifting rod form a deformable structure, if the clamp is an expanding clamp, the included angle between the lower end of the clamping arm and the inner side of the counterweight base is an obtuse angle, and if the clamp is a clamping clamp, the included angle between the lower end of the clamping arm and the inner side of the counterweight base is an acute angle; and the enabled clamping arm resetting device is used for resetting the included angle between the clamping arm and the counterweight base in an enabled control mode and enabling the included angle between the clamping arm and the counterweight base to be in an adjustable state in a disabled control mode. The crane comprises a lifting rope and the lifting appliance, and the lifting rope is fixedly connected with the lifting rod in the B-axis direction. The clamping force amplification effect on an object can be conveniently achieved through small starting force.

    本发明涉及一种吊具的使用方法、吊具、吊机,包括:至少两条夹臂与配重基座连接形成夹具;提拉杆与配重基座滑动连接,设提拉杆与配重基座的滑动轴为B轴;配重基座、夹臂、传动装置和提拉杆构成可变形结构,且若夹具为撑胀夹具,夹臂的下端与配重基座的内侧夹角为钝角,若夹具为抱夹夹具,夹臂的下端与配重基座的内侧夹角为锐角;可使能式夹臂复位装置用于在使能控制模式下复位夹臂与配重基座的夹角,在失能控制模式下使夹臂与配重基座的夹角为可调整状态。一种吊机,包括吊绳和前述的吊具,吊绳与在B轴方向上与提拉杆固定连接。使用它们便于小的启动力实现对物体的夹持力放大效果。
