<p>The excavator (10) has a chassis (14) including two axes (20, 22), wheels (16, 18) for road travel, and wheels (34, 36) for rail travel. The wheels (34, 36) are supported by two rockers. The rockers are supported in an attaching frame, and are pivotable around a pivoting point (28) by a hydraulic cylinder (38). The rockers are alternatively and strongly connected with each other by a transverse rod. The transverse rod has a pipe that is strongly connected with a closely lying rocker, by a screw connection. The transverse rod is received in the rockers, in a form-fitted manner.</p> |
