REVOLUTION TYPE CONSTRUCTION MACHINE
PROBLEM TO BE SOLVED: To protect an exterior cover not to contact an obstacle even when the obstacle exists at a height position opposite to the exterior cover above a revolving frame.SOLUTION: A rear super-small revolution type hydraulic shovel includes an exterior cover 8 including an opened/closed door 8a, and a guard structure 10 for protecting the exterior cover 8, the guard structure 10 including a door guard part 12 formed into a shape along the side-face shape of the exterior cover 8 in a planar view to move the opened/closed door 8a to be opened/closed when the opened/closed door 8a included in the exterior cover 8 is opened/closed, the guard structure 10 being arranged to approximately correspond to a trajectory 27 drawn by a revolution radius 26, in which fixing means such as sheet screws 13 including bolts 14, 15 are provided for fixing the guard structure 10 to a revolving frame 8a.
【課題】旋回フレームよりも上の外装カバーに対向する高さ位置に障害物が存在する場合でも、外装カバーを障害物に接触しないように保護する。【解決手段】本発明は、開閉扉８ａを含む外装カバー８と、この外装カバー８を保護するガード構造１０とを備えた後方超小旋回型油圧ショベルにおいて、ガード構造１０は、平面視で外装カバー８の側面形状に沿う形状に形成され、外装カバー８に含まれる開閉扉８ａの開閉に際しては開閉扉８ａの開閉を可能に動かすことのできる扉ガード部１２を含み、ガード構造１０を旋回半径２６によって描かれる軌跡２７に略一致させるように配置し、このガード構造１０を旋回フレーム８ａに固定させるシートスクリュー１３等、ボルト１４，１５などを含む固定手段を備えている。【選択図】図３
