従来技術の昇降用手摺りは、上部旋回体前部の右端部付近に設けられていた。 油圧ショベルを林道工事などの狭隘地で使用するとき、上記位置に取付けた手摺 りだと、機械の旋回あるいは走行時に、張りだした樹木の枝や障害物などに接触 して、手摺りが曲がったり、破損することが多く発生した。本考案は、上記の問 題点を解決することを目的とする。 The lifting handrail of the prior art is provided near the right end of the front part of the upper swing body. When the hydraulic excavator is used in a narrow area such as forest road construction, if the handrail attached to the above position contacts the tree branches or obstacles that project when the machine turns or runs, the handrail will bend. It often happened to be damaged. The present invention aims to solve the above problems.

本考案の昇降用手摺りは、上部旋回体の昇降用通路の機体中央部寄りに手摺り を設け、その一端を上部旋回体下部の前面部に取付け、他の一端を上部旋回体の 上面部に取付けて、構成した。 The lifting handrail of the present invention is provided with a handrail near the center of the body of the lifting passage of the upper revolving structure, one end of which is attached to the front part of the lower part of the upper revolving structure, and the other end is attached to the upper surface of the upper revolving structure. Installed and configured.
【０００５】[0005]
油圧ショベルを使用するとき、エンジンその他機器類の点検、修理などメンテ ナンスのために上部旋回体の上部に昇る機会も多く、その昇降用通路は、トラッ クシュ−上面よりステップ及びボックス上面部を経て、フュエルタンク上面部す なわち上部旋回体上面部へと至るものがほとんどである。本考案では、その昇降 用通路の機体中央部寄りで、かつ通路に沿って昇降用手摺りを設けた。したがっ て、オペレ−タは上記手摺りを利用して、上部旋回体の上面部へ安全に昇降する ことができ、また、狭隘地の作業においても、障害物による手摺りの接触、破損 を激減できる。 When using a hydraulic excavator, there is often an opportunity to climb to the upper part of the upper revolving structure for maintenance such as inspection and repair of the engine and other equipment, and its elevating passage has its upper and lower passages from the track-top through the step and box top. In most cases, the upper surface of the fuel tank, that is, the upper surface of the upper revolving structure is reached. In the present invention, a handrail for raising and lowering is provided near the center of the body of the raising and lowering passage and along the passage. Therefore, the operator can use the above handrails to safely move up and down to the upper surface of the upper revolving structure, and even when working in narrow spaces, the contact and damage of the handrails due to obstacles are drastically reduced. it can.

以下、本考案の実施例を図面に基づいて詳細に説明する。図１は、本考案の手 摺りを装着した油圧ショベルの要部斜視図である。図において、従来技術と同一 構成要素を使用するものに対しては同符号を付す。１３は上部旋回体、１４は昇 降用手摺りである。 Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. FIG. 1 is a perspective view of a main part of a hydraulic excavator equipped with a handrail according to the present invention. In the figure, the same reference numerals are given to those using the same constituent elements as those in the prior art. 13 is an upper revolving structure, and 14 is an ascending / descending handrail.
【０００７】 次に、本考案の手摺り１４の構成を図１について述べる。本考案の手摺り１４ は、上部旋回体１３の右前部で、昇降用通路の機体中央部寄りに配設し、その一 端をアッパフレ−ム３の前面部に取付け、他の一端をフュエルタンク６の上面部 に取付けている。Next, the structure of the handrail 14 of the present invention will be described with reference to FIG. The handrail 14 of the present invention is disposed on the right front part of the upper swing body 13 near the center of the body of the lifting passage, one end of which is attached to the front part of the upper frame 3 and the other end is attached to the fuel tank. It is attached to the upper surface of 6.
【０００８】[0008]
従来技術の手摺りは、上部旋回体前部の右端部付近に取付けていたので、狭隘 地で稼働するとき、障害物に接触して破損させることが多かった。しかし本考案 では、上部旋回体の中央部寄りに取付けたので、手摺りを破損させることがなく なった。これにより、車体上部への昇降も安全にでき、さらに修理費用を低減で きる。 Since the handrail of the prior art is attached near the right end of the front part of the upper swing body, it often comes into contact with an obstacle and breaks when operating in a narrow space. However, in the present invention, the handrail is not damaged because it is mounted near the center of the upper swing body. As a result, it is possible to safely move up and down to the upper part of the vehicle body and further reduce repair costs.
