| Zusammenfassung: | PROBLEM TO BE SOLVED: To avoid acting of an excessive load on a handrail, without hindering a visual field of an operator when operating a construction machine, by being usable as the handrail in work on an upper turning body, without forming the handrail provided in the rear of a cab as a separate shape, in the construction machine.SOLUTION: A construction machine 1 comprises a lower travel body 2, an upper turning body 3 turnably mounted on the lower travel body and having a cab 6 capable of boarding the operator and a front 4 having one end part connected to the upper turning body. The handrail for the construction machine comprises a pipe bending-shaped handrail body 30 provided in an upper part of the upper turning body and on the back face side of the cab, handrail fixing means 40 for fixing a leg part 30a of the handrail body and handrail holding means 20 installed on the back face side of the cab for holding the handrail body in the cab.
【課題】建設機械において、キャブ後方に設けた手摺りを分離形状とすることなく、上部旋回体上での作業中は手摺りとして使用でき、建設機械の運転中には作業者の視野を妨げることがないようにするとともに、手摺りに過大な負荷が作用するのを回避する。【解決手段】建設機械１は、下部走行体２と、この下部走行体上に旋回可能に搭載され、作業者が搭乗可能なキャブ６を有する上部旋回体３と、一端部がこの上部旋回体に接続されたフロント４とを有する。建設機械用手摺りは、上部旋回体の上部であってキャブの背面側に設けられたパイプ折り曲げ形状の手摺り本体３０と、この手摺り本体の脚部３０ａを固定する手摺り固定手段４０と、手摺り本体をキャブに保持するためにキャブの背面側に取り付けた手摺り保持手段２０とを備える。【選択図】 図２ |
