[0003] For example, application number: CN202311529108.5 discloses a single-beam crane for rolling mills, including: a moving car body, a lifting mechanism, a deadweight clamping assembly and a hanging beam assembly. A counterweight turntable is rotatably mounted on the top surface of the moving car body. A controller for controlling the moving car body, the counterweight turntable and the lifting mechanism is provided inside the moving car body. The lifting mechanism includes a connecting rod lifting assembly, a telescopic beam arm, a small arm assembly and an end turntable movably mounted at one end of the small arm assembly. The connecting rod lifting assembly is located inside the counterweight turntable. By setting a new type of lifting clamping assembly, the hanging beam assembly and the deadweight clamping assembly cooperate with each other, and the sliding movement of the deadweight clamping assembly on the surface of the hanging beam assembly replaces the flexible sling lifting of the rolling mill. The deadweight clamping assembly can slide restrictively on the surface of the limit plate to adapt to the lifting of rolling mills of different sizes, and limit the free deflection movement of the rolling mill, which is convenient for docking and installation with the rolling mill and improves the safety of lifting.
