摘要： Provided is an upper slewing body (1) allowing elements to be compactly arranged while preventing required length of a hydraulic pipe from increase. The upper slewing body (1) includes an upper frame (10), an engine (31), a hydraulic pump (33) coupled thereto, a control valve (60) forward of the engine and rearward of a slewing axis, and a rear tank (50) between the engine (31) and the control valve (60). The control valve (60) is oblique to a frame lateral direction so as to locate a front end portion (65) thereof forward of an inner end portion (67) thereof. The rear tank (50) has a rear opposition side surface (53) opposed to a rear side surface (63R) of the control valve (60) while being oblique to the rear side surface thereto.

摘要： To permit selective mounting of a small first control valve unit or a large second control valve unit on bodies of construction machines of different models the same family without incurring an increase in the number of kinds of parts or components.
A mount structure for a control valve unit is provided for arrangement on a compact excavator. The control valve unit can be either a small first control valve unit (11A) and a large second control valve unit (11B). On a bracket (10) for these control valve units (11A, 11B), the first or second control valve unit (11A or 11B) is selectively mounted. The mount structure is constructed such that upon mounting the first or second control valve unit (11A or 11B) on the bracket (10), a barycentric position (G) of the bracket (10) with the first control valve unit (11A) mounted thereon and a barycentric position (G) of the bracket (10) with the second control valve unit (11B) mounted thereon are located on an imaginary line that connects paired hanging-member fixingportions of the bracket (10) with each other.
