Abstract
Disclosed are a bending boom, a boom device and a work machine. The bending boom includes a middle portion and two extending portions. The middle portion is configured to connect external components. The extending portion has a first side wall and a second side wall opposite to the first side wall. The first side wall is flush with middle portion, and the second side wall is bent from middle portion towards a direction near first side wall. The two extending portions are connected to two opposite ends of middle portion. By providing the matching middle portion and extending portions, a situation in which stress concentration occurs at the middle portion can be prevented, which improves stress condition of the bending boom, and improves durability of the bending boom, the boom device and the work machine.
