PROBLEM TO BE SOLVED: To provide an undulating body which allows the assembling work while easily joining multiple constituting members each other and an assembling method of a work machine with the undulating body.SOLUTION: A lattice mast comprises a lower mast 17A and an intermediate mast 17B. The lower mast 17A includes a first connection part 17A1, and the intermediate mast 17B includes a second connection part 17B1 and a first guide mechanism 73. The first guide mechanism 73 has a guide surface 73A and a guide surface 73C. A first outer peripheral surface 61A of the first connection part 17A1 moves along the guide surface 73A after abutting on the guide surface 73A, then the first outer peripheral surface 61A abuts on the guide surface 73C, and a first hole 62 coincides with a second hole 72. The first connection part 17A1 and the second connection part 17B1 are connected by inserting a connecting pin into the first hole 62 and the second hole 72.SELECTED DRAWING: Figure 8
【課題】複数の構成部材同士を容易に連結しながら組み立て作業を行うことが可能な起伏体および当該起伏体を備えた作業機械の組立方法を提供する。【解決手段】ラチスマストは、下部マスト17Aと中間マスト17Bとを備える。下部マスト17Aは第1連結部17A1を備え、中間マスト17Bは第2連結部17B1と第1ガイド機構73とを備える。第1ガイド機構73は、ガイド面73Aと、ガイド面73Cと、を備える。第1連結部17A1の第1外周面61Aがガイド面73Aに当接した後、ガイド面73Aに沿って移動されると、第1外周面61Aがガイド面73Cに当接し、第1孔部62と第2孔部72とが合致する。第1孔部62および第2孔部72に連結ピンが挿入され、第1連結部17A1と第2連結部17B1とが連結される。【選択図】図8
