Claims

[Scope of utility model registration request]

In a construction machine that has a swing wheel between an upper rotating body and a lower traveling body on which work attachments are attached, and in which the upper rotating body can freely rotate with respect to the lower traveling body, a swing ring 4 is attached to the upper surface of the lower frame 2,
a lower base frame 1 fixed to the upper surface of the swing wheel 4;
3 with brackets 6, 6', 16, 16',
The lower ends of the links 5, 5', 15, 15' of equal length are rotatably attached to the brackets 6, 6', 16, 16', respectively.
, 15' of the upper base frame 14 whose upper ends are fixed to the lower surface of the upper revolving body 3,
8', 18, and 18', and the bracket 11 of the lower base frame 13 and the bracket 12 of the upper base frame 14 are connected by a hydraulic cylinder 10, so that the upper revolving body 3 can be moved in the front-rear direction. A mechanism for moving the upper rotating body of construction machinery.
