Abstract
Provided is a door hinge for heavy equipment, including: first plate and a second plate disposed on a hinge shaft of a door of heavy equipment and hinge-coupled to each other to open and close the door; and a stay unit rotatably disposed on the first plate and supporting the second plate when the door is opened to prevent the door from being closed. Thus, according to the present invention, an open state of a door can be maintained by only the stay unit without mounting a bracket by overcoming the limitation that the bracket for mounting a separate door stay must be mounted to a door body in order to maintain the open state of the existing door during opening of the door.
