  • Control valve attachment structure for construction machine
    Patent number: 8857549
    Abstract: A mount structure for a control valve unit is provided 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. The control valve unit may be a small first control valve unit or a large second control valve unit. The mount structure is constructed such that upon mounting the first or second control valve unit on a bracket on which the first or second control valve unit may be selectively mounted, a barycentric position of the bracket with the first control valve unit mounted thereon and a barycentric position of the bracket with the second control valve unit mounted thereon are located on an imaginary line connecting paired hanging-member fixing portions of the bracket.
