APPARATUS FOR FIXING UPPER SWING STRUCTURE OF CONSTRUCTION MACHINE
An apparatus for retaining an upper pivoting body of a construction machine having a lower traveling body includes a protrusion on a lower surface of the upper pivoting body, a socket portion on an upper side of the lower traveling body that couples with the protrusion, an elastic member on a lower side of the socket portion that elastically supports the socket portion, a first tapered member on a lower side of the elastic member to support the elastic member, a lower surface of the first tapered member having a sloping surface, and a second tapered member on a lower side of the first tapered member. The upper surface of the second tapered member has a sloping surface that makes sliding contact with the first tapered member. The second tapered member lifts the socket portion, through a horizontal movement, to be coupled with the protrusion or lowers the socket portion to be separated from the protrusion.
