REVOLVING WORK MACHINE
To provide a revolving work machine capable of reducing the number of bias members for bearing the weight of a fuel cylinder when the fuel cylinder is rotated in a downward direction to thereby ensure a large installation space for the fuel cylinder.SOLUTION: The revolving work machine includes: a revolving table; a motor mounted on the revolving table; a working unit provided to the revolving table; and a support mechanism that has a support rotating body that supports rotatably in the vertical direction a fuel cylinder storing fuel for the motor. The support mechanism includes: a biasing member that bears the weight of the fuel cylinder and gives an elastic rebound force in a direction to inhibit the downward rotation of the support rotating body; and an auxiliary mechanism that increases the elastic rebound force acting on the support rotating body.SELECTED DRAWING: Figure 11
【課題】燃料ボンベを下方向に回動したときに燃料ボンベの重量を受ける付勢部材の数を削減可能とし、これによって燃料ボンベの設置スペースを広く確保すること。【解決手段】旋回作業機は、旋回台と、前記旋回台に搭載された原動機と、前記旋回台に設けられた作業装置と、前記原動機の燃料を収容する燃料ボンベを上下方向に回動可能に支持する支持回動体を有する支持機構と、を備え、前記支持機構は、前記燃料ボンベの重量を受けて前記支持回動体の下方への回動を阻害する方向に弾性反発力を付与する付勢部材と、前記支持回動体に作用する前記弾性反発力を増大させる補助機構と、を有している。【選択図】図１１
