To provide a handrail device capable of improving safety and working efficiency.SOLUTION: A handrail device has plural struts 2 installed in a standing state on a boom with a space therebetween in a longitudinal direction of the boom, a handrail bar 3 horizontally arranged at a distance apart from each strut 2, a connection member 6 provided at each strut 2 to connect the strut 2 with the handrail bar 3, and a metal fitting 11 engaged in the handrail bar 3 and being movable in the axial direction of the handrail bar 3. The metal fitting 11 has an engaging part 23 engaged in the handrail bar 3, and a projecting part 24 which projects from the engaging part 23 toward the direction intersecting the axial direction and to which a safety belt is attached. The handrail bar 3 is hollow and accommodates the engaging part 23 in its inside, and the handrail bar 3 has a slit 3b formed from one end of the axial direction to the other through which the projecting part 24 passes.SELECTED DRAWING: Figure 6

    【課題】安全性および作業効率を向上させることが可能な手摺装置を提供する。【解決手段】ブームの上に、ブームの長手方向に互いに間隔をあけて立てて設けられた複数の支柱2と、各支柱2に対して間隔をあけて、水平方向に配置された手摺り棒3と、支柱2ごとに設けられ、支柱2と手摺り棒3とを連結する連結部材6と、手摺り棒3に係合し、手摺り棒3の軸方向に移動自在な金具11と、を有する。金具11は、手摺り棒3に係合する係合部23と、軸方向に交差する方向に係合部23から突出し、安全帯が取り付けられる突出部24と、を有する。手摺り棒3は中空であって、その内部に係合部23を収容し、手摺り棒3には、突出部24が通過するスリット3bが軸方向の一端から他端にわたって形成されている。【選択図】図6
