Abstract

See full text

A method for coupling a machine frame (12) of an earth working machine (10) to a working device (28) between the machine frame (12) and a substrate (U) encompasses the following steps:

    arranging the machine frame (12) and the working device (28) between the machine frame (12) and the substrate (U);aligning the receiving portion (42) and working device (28) relative to one another in such a way that fastening formations (56, 60) of the working device (28) are lined up, along a spacing direction, with fastening counter-formations (58, 62) of the machine frame (12);bringing the fastening formations (56, 60) and fastening counter-formations (58, 62) closer to one another; andoperably fastening the working device (28) onto the receiving portion (42).According to the present invention the aligning step encompasses the following sub-steps:connecting the machine frame (12) and the working device (28) to one another by means of a connecting apparatus (76), in such a way that the working device (28) is movable in response to its weight, parallel to the effective direction of gravity (g) and orthogonally thereto, relative to the machine frame (12); thenallowing the working device (28) to hang on the machine frame (12); and thensupporting the working device (28).
