CAB FALL PREVENTING STRUCTURE FOR WORK MACHINE
PROBLEM TO BE SOLVED: To provide a cab fall preventing structure for a work machine which can prevent falling off of a fall preventing device.SOLUTION: One end side of a stopper shaft portion 51 of a fall preventing device 16 is inserted into a through hole 37a. The other end side of the stopper shaft portion 51 is inserted into an insertion hole 23b. A stopper main body portion 52 is provided at the other end of the stopper shaft portion 51. A part of a key member 53 is fitted into a hole portion 51c provided in a direction crossing the axial direction on one end side of the stopper shaft portion 51. The other part of the key member 53 protruding from the stopper shaft portion 51 is fixed to one of a cab 14 and a revolving frame 23. Even if the key member 53 is detached from the cab 14 or the revolving frame 23, since a part of the key member 53 is fitted in the hole portion 51c of the stopper shaft portion 51, the stopper shaft portion 51 does not come out from the through hole 37a, so that it is possible to prevent the fall preventing device 16 from falling off.SELECTED DRAWING: Figure 1
【課題】抜止装置の脱落を防止できる作業機械のキャブ抜止構造を提供する。【解決手段】抜止装置16のストッパ軸部51の一端側を貫通穴37aに挿通する。ストッパ軸部51の他端側を挿通穴23bに挿通する。ストッパ軸部51の他端にストッパ本体部52を設ける。ストッパ軸部51の一端側の軸方向と交差する方向に沿って設けた穴部51cに対してキー部材53の一部を嵌合する。ストッパ軸部51から突出するキー部材53の他部をキャブ14と旋回フレーム23との一方に対して固定する。キー部材53が仮にキャブ14または旋回フレーム23から外れた場合でも、キー部材53の一部がストッパ軸部51の穴部51cに嵌合しているため、ストッパ軸部51が貫通穴37aから抜けることがなく、抜止装置16の脱落を防止できる。【選択図】図1
