Generally, an excavator is an excavator for soil excavation, which consists of a back-ho, a clam-shell, a shovel, a hammer, an orange -peel), and so on.

In particular, excavators are required to perform various tasks such as residential land development, road and sewer construction, sea reconstruction and resurfacing, tunnels and subway construction, reclamation work, forest clearing construction, and soil loading work.

These various operations are mainly possible by replacing a bucket or the like which is coupled to the tip of the arm with a suitable one for a work purpose.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, referring to the accompanying drawings, a flat device for an excavator according to a preferred embodiment of the present invention will be described in detail.

The embodiments of the present invention can be modified in various forms, and the scope of the present invention should not be construed as being limited to the embodiments described in detail below. This embodiment is provided to more fully describe the present invention to those skilled in the art. Therefore, the shapes and the like of the elements in the drawings can be exaggeratedly expressed to emphasize a clearer description. It should be noted that in the drawings, the same members are denoted by the same reference numerals. Detailed descriptions of well-known functions and constructions which may be unnecessarily obscured by the gist of the present invention are omitted.
