Patent ID: 7722008

Claim:
A load support apparatus for a cabin of a heavy equipment, comprising: vibration absorption apparatuses installed between an upper frame of a heavy equipment and a cabin for thereby elastically supporting the cabin with respect to the upper frame, wherein the cabin is provided with a bottom plate at its lower side and mounted on the upper frame; stoppers which include an escape prevention part at one side thereof and, an engaging part extended downwards from the escape prevention part with the engaging part being detachably fixed to the upper frame, and with the escape prevention part being installed on the upper side of the upper frame through the bottom plate, for thereby preventing the cabin from being, released said escape prevention part including a bolt head shaped stop head part, and a washer shaped stopper plate which is integrally engaged with the stop head part; and a vibration prevention apparatus which includes a vibration prevention member engaged with an outer rear side of the cabin, a support bracket installed on an upper side of the upper frame for receiving the vibration prevention member therein, and an elastic member which is installed between an outer side of the vibration prevention member and an inner side of the support bracket for thereby absorbing the left and right direction vibrations which are transferred from the upper frame to the cabin, the vibration prevention member engaging with an outer side of the cabin by disposing a fixing bracket which is fixed to the rear side of the cabin in parallel with respect to the upper frame and the support bracket being formed into a hollow cylindrical shape which is longitudinally extended in a vertical direction and being fixed to the upper frame; wherein the stoppers further comprise: a rotation prevention plate which includes an engaging surface fixed to one side of the upper frame and an extended surface which is extended upwards over an upper side of the upper frame, the engaging surface being provided with a fixing hole and fixed to one side of the upper frame by a rotation-prevention fixing member, the extended surface being provided with at least one straight line part formed at the edge portion thereof in channel shapes; and a cylindrical rotation prevention boss which is installed between the engaging part and the escape prevention part and has a rotation prevention part formed on an outer surface corresponding to the straight line part, thereby preventing the escape prevention part from loosening by fixedly contacting the rotation prevention part with the straight line part.
