Abstract

The invention relates to the field of engineering machinery, and specifically, to a polygonal boom support, a telescopic boom, and an aerial work platform. The polygonal boom support comprises an upper cover part (10) located at the top of the polygonal boom support, a bottom plate part (20) located at the bottom of the polygonal boom support, and side parts (30) located between the upper cover part (10) and the bottom plate part (20), wherein the thicknesses of the side parts (30) are smaller than the thicknesses of the upper cover part (10) and the bottom plate part (20). By arranging the side parts with the relatively small thicknesses, the height of the polygonal boom support can be relatively increased; moreover, the inertia moment of the cross section of the polygonal boom support isincreased; and thus, the rigidity of the polygonal boom support is obviously improved.

Description

technical field [0001] The invention relates to engineering machinery, in particular to a polygonal boom, a telescopic boom and an aerial work platform. Background technique [0002] High-altitude operation equipment needs to ensure the safety and stability of personnel's high-altitude operations. For example, for aerial work platforms, the rigidity requirements for the telescopic boom are relatively high. Especially for high-meter section aerial work platforms (generally above 42 meters), the height requirements for the boom of the telescopic boom are higher. If the boom with the same stiffness is used, the shaking of the high-meter section of the aerial work platform is much larger than that of the low-meter section of the aerial work platform, and the operator's experience is very poor. At present, the telescopic boom adopts a rectangular boom. In order to improve the rigidity of the boom, it is usually necessary to increase the height, width, and thickness of the boom,...
