Abstract:
A roll over protection structure for a work machine, the work machine having a centerline in the direction of travel, the structure comprising:an operator cab having a plurality of faces; at least one rotational mount connecting a first face of said operator cab to the work machine, said rotational mount providing for rotation of said cab about an axis parallel to the center line of the work machine; and at least one deforming member connecting a second face of said operator cab with the work machine, said deforming member including a U-shaped member having a first leg connected with a chassis of the machine and a second leg connected with said operator cab, said U-shaped member characterized by elastic deformation responsive to normal operational shocks acting on said cab, and by controlled plastic deformation responsive to larger forces indicative of a machine roll over.
