Abstract: A swing control apparatus for a swing type hydraulic shovel capable of reducing impact at a stroke end of swing at a low cost. For this purpose, the swing control apparatus includes a swing angle detector for detecting that a swing angle of a working machine, which is swingingly driven by swing drive means, is within a predetermined angle range short of a stroke end, and a controller for outputting a speed reduction command to reduce a swing speed gradually from a position at a predetermined angle short of the stroke end of a swing toward the stroke end, based on a swing angle signal inputted from the swing angle detector.

Abstract: A work machine for achieving efficient coordinated operations by a plurality of kinds of operating units, comprising first and second swivel driving members and first and second swivel joints, wherein a first swiveling base bearing a first operating unit and a second swiveling base bearing a second operating unit can swivel around a common swiveling axis independently relative to a traveling base.

Abstract: An apparatus for attaching an implement to an earth moving vehicle, comprising a pair of lift arms for lifting the implement, a pair of tilt rods for effecting tilting motion of the implement, a pair of lower couplers pivotally connected to said lift arms at one end thereof, and a pair of upper couplers pivotally connected to said pair of tilt rods, the upper and lower couplers being pivotally connected with each other. The pair of lower couplers and pair of upper couplers are transversely connected by connecting beams, respectively. The connecting beams are adapted to engage with C-shaped hooks fixedly secured to the rear surface of the implement.
