To provide a handrail for assembling work of a derricking member of a work machine, which can reduce the weight of pillars and is easier to operate with a simpler structure than conventional handrails.SOLUTION: A handrail for assembling work of a derricking member of a work machine comprises a first pillar 10 and a second pillar 11(33), a first bracket 12 that supports the first pillar 10 so that the first pillar 10 can move in its axial direction, a second bracket 17 (34) that supports the second pillar 11 (33) so that the second pillar 11 can rotate around its base or the second pillar 33 can move in its axial direction, and guide ropes (14, 15, 36) that are guided between the tip of the first pillar 10 and the tip of the second pillar 11 (33). When the first pillar 10 and the second pillar 11 (33) are in the use position, the first pillar 10 and the second pillar 11 (33) are inclined with respect to the longitudinal direction of a unit derricking member 1 in the direction where their respective tips are separated from each other.SELECTED DRAWING: Figure 1

    【課題】支柱の軽量化が可能で、且つ、従来よりも簡易な構成で操作も行い易い作業機械の起伏部材組立作業用手摺りを提供すること。【解決手段】起伏部材組立作業用手摺りは、第1支柱10および第2支柱11(33)と、第1支柱10がその軸方向に移動するように、第1支柱10を支持する第1ブラケット12と、第2支柱11がその基端部まわりに回動するように、または第2支柱33がその軸方向に移動するように、第2支柱11(33)を支持する第2ブラケット17(34)と、第1支柱10の先端部と第2支柱11(33)の先端部との間に案内されるガイドロープ(14、15、36)と、を備える。第1支柱10および第2支柱11(33)が使用位置にあるとき、それぞれの先端部が互いに離れる方向へ、第1支柱10および第2支柱11(33)が単位起伏部材1の長手方向に対して傾斜している。【選択図】図1
