Claim 0:
1. A tandem walking beam suspension system for a track-mounted vehicle defining a sub-frame and a track, the system comprising:
a main walking beam defining a main walking beam first end and a main walking beam second end opposite the main walking beam first end, the main walking beam being pivotally supported by the sub-frame of the track-mounted vehicle to define a pivot axis intermediate the main walking beam first and second ends;
a first pair of parallel and spaced apart secondary walking beams pivotably mounted about the main walking beam first end;
a second pair of parallel and spaced apart secondary walking beams pivotably mounted about the main walking beam second end;
a first pair of rollers rotatably mounted in-between and to the first pair of parallel and spaced apart secondary walking beams;
a second pair of rollers rotatably mounted in-between and to the second pair of parallel and spaced apart secondary walking beams, the first and second pairs of rollers being configured to roll along the track when the track-mounted vehicle is in displacement; and
a compression device interconnecting the sub-frame and the main walking beam at the pivot axis thereof and configured for providing vertical displacement of the main walking beam including the pivot axis relative to the sub-frame.
