PROBLEM TO BE SOLVED: To reinforce a desired portion after a latticed boom is assembled and improve the workability of reinforcement work.SOLUTION: A reinforcement structure of a latticed boom has reinforcement members 2 which are provided on outer peripheral surfaces of at least one of main pipes 41 and lattice pipes 42 and extend in axial directions of the pipes. The two or more reinforcement members 2 are provided in a circumferential direction of the outer peripheral surfaces of the pipes (the main pipes 41, the latticed pipes 42). Further, each reinforcement member 2 is disposed between connection portions 44 of the main pipes 41 and the lattice pipes 42.SELECTED DRAWING: Figure 3

    【課題】ラチスブームを組み立てた後に所望の箇所を補強することができるとともに、補強作業の作業性を向上させることができるようにする。【解決手段】メインパイプ41およびラチスパイプ42の少なくとも一方の外周面に設けられて、その軸方向に延びる補強部材2を有する。補強部材2は、パイプ(メインパイプ41、ラチスパイプ42)の外周面の周方向に2以上設けられている。また、補強部材2は、メインパイプ41とラチスパイプ42との接続箇所44同士の間に配置されている。【選択図】図3
