COMPACT HYDRAULIC SHOVEL
PROBLEM TO BE SOLVED: To improve workability of inspection and maintenance by forming an opening for inspection large.SOLUTION: A compact hydraulic shovel comprises: an opening 33 for inspection which is provided between a driver seat base 14 and a tank-side surface cover 26 on a rear sides of respective vertical plates 7B, 7C of a revolving frame 7 for inspecting a power source, and inclined to be raised from a front side to a rear side to be open; an inspection cover 34 formed of an inclined surface that a lower boom 6A and the respective hydraulic hoses 31 stay along when the opening 33 for inspection is detachably closed and an offset front device 6 is placed in a very small revolving attitude; a lower cover 35 which is provided below the inspection cover 34 and to which a front side part of the inspection cover 34 is detachably fastened using a screw member; and a guide member 42 which is provided to the lower cover 35 at a position nearby the screw member and guides the respective hydraulic hoses 31 of the offset front device 6 so that the respective hydraulic hoses 31 leaves the screw member toward a boom foot part 6A1.SELECTED DRAWING: Figure 6
【課題】 点検用開口を大きく形成することにより、点検、整備の作業性を向上する。【解決手段】 動力源を点検するために旋回フレーム７の各前縦板７Ｂ，７Ｃの後側に位置して運転席台座１４とタンク側面カバー２６との間に設けられ前側から後側に向けて立ち上がるように傾けられて開口した点検用開口３３と、点検用開口３３を着脱可能に閉塞しオフセットフロント装置６を超小旋回姿勢としたときロアブーム６Ａと各油圧ホース３１とが沿う傾斜面からなる点検カバー３４と、点検カバー３４の下側に設けられ点検カバー３４の前側部位がねじ部材を用いて取外し可能に締着される下カバー３５と、ねじ部材の近傍に位置して下カバー３５に設けられオフセットフロント装置６の各油圧ホース３１がねじ部材からブームフート部６Ａ１に向けて離れるように各油圧ホース３１をガイドするガイド部材４２とを備えている。【選択図】 図６
