COMPACT HYDRAULIC SHOVEL
PROBLEM TO BE SOLVED: To provide a compact hydraulic shovel having a space secured for moving from an entrance to a driver seat when getting on/off, a wide operating range of a boom secured, and a living space secured around the driver seat within a range that would not hinder operation.SOLUTION: A rear small revolving-type mini shovel of the present invention includes: a revolving superstructure 2 having a rear edge part formed to be rotatable within a vehicle width; a work device 3 including a boom 3a; a driver seat 4; a pair of driving levers 7a, 7b; and an openable front guard 11 disposed between the boom 3a and the pair of driving levers 7a, 7b for blocking a flying foreign object on the driver seat 4. The front guard 11 includes a recess 11c for avoiding interference with the boom 3a of the work device 3 when the boom 3a is in a highest lifted state. A height position of the recess 11c has been set to be higher than a top edge of the pair of driving levers 7a, 7b.SELECTED DRAWING: Figure 1
【課題】乗降口から運転席への乗降時の移動空間を確保でき、ブームの作動範囲を広く確保でき、かつ運転席の居住空間を支障を生じさせない範囲で確保できるようにする。【解決手段】本発明は、後端部が車幅内で旋回可能に形成された旋回体２と、ブーム３ａを含む作業装置３と、運転席４と、一対の走行レバー７ａ，７ｂと、ブーム３ａと一対の走行レバー７ａ，７ｂの間に配置され運転席４への異物の飛来を阻止する開閉可能なフロントガード１１とを備えた後方小旋回型ミニショベルであって、フロントガード１１は、作業装置３のブーム３ａの最上げ状態におけるブーム３ａとの干渉を回避するくぼみ部１１ｃを有し、くぼみ部１１ｃの高さ位置を一対の走行レバー７ａ，７ｂの上端よりも高い位置に設定してある。【選択図】図１
