The present invention provides a track-type carriage system for heavy vehicles, and, in the preferred embodiment, a track-type carriage system for an articulated steering seismic vibrator vehicle. The carriage system consists of four track modules, two fore and two aft, each independently mounted at one end of a heavy axle and bearing a proportionate share of the vehicle weight as applied to the track module via a ground pressure cylinder. Each track module includes an S-shaped frame interrelating a large drive wheel mounted to the axle, a pair of forwardly mounted idler wheels and a plurality of mid-wheels. A stabilizing mechanism manages torsional and lateral forces and also accommodates for fore and aft movement of the track module frame.
