SMALL HYDRAULIC SHOVEL
PROBLEM TO BE SOLVED: To provide a small hydraulic shovel of which height can be changed by rotating or separating an upper support pillar relative to a lower support pillar of a canopy and that enables enhancement of strength of a portion connecting the lower support pillar and the upper support pillar with each other.SOLUTION: A small hydraulic shovel includes: right and left support pillars 9 provided on the rear side of a driver seat 7; and a roof 10 supported by the right and left support pillars 9. Each of the support pillars 9 includes: a lower support pillar 11 having a connection portion 14 on the upper end side; an upper support pillar 12 having a connection portion 16 rotatable to the connection portion 14 on the lower end side; a cylindrical fixation member 18 covering the connection portion 14 and its adjacent portion of the lower support pillar 11 and the connection portion 16 and its adjacent portion of the upper support pillar 12; and fixation bolts 23 and nuts 24 for detachably fixing the cylindrical fixation member 18 to the lower support pillar 11 and the upper support pillar 12.SELECTED DRAWING: Figure 3
【課題】キャノピの下側支柱に対して上側支柱を回動又は分離して小型油圧ショベルの高さを変更することができ、かつ、下側支柱と上側支柱を接続する部分の強度を高めることができる小型油圧ショベルを提供する。【解決手段】小型油圧ショベルは、運転席７の後側に設けられた左右の支柱９と、左右の支柱９で支持されたルーフ１０とを備えている。各支柱９は、上端側に接続部１４を有する下側支柱１１と、下端側に接続部１４に対して回動可能な接続部１６を有する上側支柱１２と、下側支柱１１の接続部１４及びその隣接部と上側支柱１２の接続部１６及びその隣接部を覆う筒状固定部材１８と、筒状固定部材１８を下側支柱１１及び上側支柱１２に着脱可能に固定する固定ボルト２３及びナット２４を備えている。【選択図】図３
