Description
請求項1の作業機の手摺装置は、下部走行体上に旋回装置を介して旋回フレームを設置し、
前記旋回フレーム上の前部の片側に運転室を搭載すると共に、後部にパワーユニットを搭載して上部旋回体を構成し、
前記上部旋回体における前記運転室の搭載部の反対側の外側部に頂部が前記上部旋回体の上面より上方に突出する手摺を立設し、
前記手摺より内側の上部旋回体の上面を前記上部旋回体の前後方向の少なくとも中間部から前記パワーユニット上に至る通路として用いる作業機の手摺装置において、
前記手摺を、前記上部旋回体に固定する下手摺と、この下手摺に取付ける上手摺からなる分割構造とし、
前記上手摺を前記下手摺に対して前記上部旋回体の内側に起伏可能に取付けると共に、
前記上手摺を前記上部旋回体の内側に倒した際に、前記上手摺で前記通路を遮断する構成にしたことを特徴とする。
The handrail device of the working machine according to claim 1 is provided with a turning frame on a lower traveling body via a turning device,
A driver's cab is mounted on one side of the front part on the revolving frame, and a power unit is mounted on the rear part to constitute an upper revolving body.
It said top outside portion of the opposite side of the mounting portion of the cab in the upper rotating body is erected handrail projecting upwardly from the upper surface of the upper rotating body,
In handrail device of the working machine used as a passage leading onto the power unit from at least the middle portion in the front-rear direction of the upper surface of the upper rotating body of the upper rotating body inside from the handrail,
The handrail has a divided structure composed of a lower handrail fixed to the upper swing body and an upper handrail attached to the lower handrail,
The upper handrail is attached to the inner side of the upper revolving body with respect to the lower handrail so as to be able to undulate,
When defeating the handrail on the inside of the upper swing body, characterized in that the arrangement for blocking the passage in the handrail.
作業機を図1に示すように輸送トラック2上に搭載して輸送する際には、手摺22が輸送制限高さHを超えないように、図4に2点鎖線で示すように上部旋回体13の内側に倒して輸送する。この場合、固定ピン29の操作部29aをつまんでガイド溝30aの固定溝30bから外し、操作部29aをガイド溝30aに沿って移動させて固定ピン29をブラケット26のピン孔26fから引き抜く。そして操作部29aを固定溝30cに嵌めて固定ピン29がピン孔26fから引き抜かれた状態を保つ。 When the work implement is mounted on the transport truck 2 as shown in FIG. 1 and transported, the upper swing body as shown by a two-dot chain line in FIG. 4 is used so that the handrail 22 does not exceed the transport limit height H. Tilt inside 13 and transport. In this case, the operation portion 29a of the fixing pin 29 is pinched and removed from the fixing groove 30b of the guide groove 30a , the operation portion 29a is moved along the guide groove 30a, and the fixing pin 29 is pulled out from the pin hole 26f of the bracket 26. And the operation part 29a is fitted in the fixing groove 30c, and the state where the fixing pin 29 is pulled out from the pin hole 26f is maintained.
このように、上手摺24で通路18を遮断した状態において、操作部29aをガイド筒30の周方向に回して操作部29aを固定溝30bに嵌めることにより、固定ピン29が振動等によりピン孔20gから外れることを防止する。このように上手摺24を倒した状態においては、上手摺24は下手摺23の頂部より低くなるので、手摺22は輸送制限高さH以下とすることができる。 Thus, in a state where the passage 18 is blocked by the upper handrail 24, the operating portion 29a is turned in the circumferential direction of the guide tube 30 to fit the operating portion 29a into the fixing groove 30b, whereby the fixing pin 29 is pinned by vibration or the like. Prevents it from falling off 20g. Thus, in the state in which the upper handrail 24 is tilted, the upper handrail 24 is lower than the top of the lower handrail 23, so that the handrail 22 can be set to a transport restriction height H or less.
