Abstract: There is provided a singly steerable, serpentine steel track crawler. The single-track crawler can steer independently in a serpentine fashion. Two or more single crawler tracks side-by-side can be transformed into a multi-track crawler vehicle. The single-track crawler or multi-track crawler vehicle can be fitted with rubber tires for plying on paved roads. This makes it a versatile, multi-terrain vehicle for agriculture and earth-moving applications.

Abstract: A crawler belt coupling apparatus includes a first crawler belt link, a second crawler belt link, a master pin, a locking pin, and a snap ring. The master pin is inserted in first and second through holes. The master pin is provided with an insertion hole. The locking pin is press fitted into the insertion hole, and has both ends projecting relative to the master pin. The snap ring has a C-like shape, has an outer diameter larger than the first through hole, is disposed opposite to the second crawler belt link relative to the first through hole, and is attached to the master pin. The groove has a width smaller than a diameter of the master pin. The locking pin is disposed in the groove.
