The invention belongs to the technical field of engineering machinery and provides a telescopic arm unit and hoisting machine.The telescopic arm unit comprises an outer arm section, an inner arm section and a sliding block assembly, the outer arm section is a polygonal barrel arm, the inner arm section is arranged in the outer arm section and is a polygonal barrel arm, and the number of edges of the inner arm section is smaller than that of edges of the outer arm section; the sliding block assembly is arranged between the outer arm section and the inner arm section. The number of edges of the inner arm section is set to be smaller than that of the outer arm section, and on the premise that both the inner arm section and the outer arm section meet the lifting performance of the telescopic arm, the manufacturing difficulty of the inner arm section can be reduced by reducing the number of the edges of the inner arm section, so that the manufacturing cost of the telescopic arm is reduced on the whole.

    本发明属于工程机械技术领域并提供一种伸缩臂单元及起重机械,伸缩臂单元包括外臂节、内臂节和滑块组件,外臂节为多边形筒臂,内臂节设置在外臂节内并为多边形筒臂,内臂节的边数小于外臂节的边数,滑块组件设置在外臂节和内臂节之间。通过将内臂节的边数设置为小于外臂节,在内臂节和外臂节均满足伸缩臂的起重性能的前提下,通过减少内臂节的边数,能够降低内臂节的制造难度,从而从整体上降低伸缩臂的制作成本。
