のブラケツト。 A pair of boxes-shaped cross-sectional frames that support both ends of an earthwork plate attached to the front of the bulldozer body and are rotatable about the side of the car body as a fulcrum, a first arm that connects both ends of the earthwork plate, and the center thereof. In the support device for an earthwork board, the bracket for attaching the second arm provided on the frame is connected to a flat plate having a convex portion on the front side and a rib on the back side. The flat plate is made of cast iron, and the flat plate is matched with the side plate of the frame, and the longitudinal direction of the rib is in contact with and fixed to the inner side of the frame,
A bracket for a bulldozer earthmoving machine frame, characterized in that a second arm is attached to a convex portion on the front side.
