Passive Transport System for Tracked Vehickles
PTSTV is an innovative transport system that enables tracked vehicles to move using wheel-based traction powered by their own drivetrain. With a specialized rolling platform and a passive mechanical coupling to the vehicle’s drive sprockets, it allows fast and efficient relocation of heavy equipment in urban areas, over long distances, and in regions without access to rail or heavy-truck infrastructure. The system relies entirely on mechanical components—with no additional electronics or power supply—which ensures the highest level of reliability in military and industrial environments.
Key Benefits of PSTPG
✅ Triple increase in the service life of tracked vehicle drivetrains
Switching movement from tracks to wheels significantly reduces engine and drivetrain load, especially on hard road surfaces.
✅ Elimination of track wear during transport
Since the tracks are not used to propel the vehicle, operational costs are drastically reduced.
✅ Unlocking heavy-equipment logistics
PSTPG reduces dependence on trucks, trailers, and external transport assets. Tracked vehicles can be relocated at scale and in multiple directions simultaneously.
✅ High mobility in armored maneuvers
The platform’s increased movement speed (×1.5 transmission ratio) enables much faster tactical and operational-level maneuvers.
✅ Full control from the vehicle’s own controls
The platform steers and moves in sync with the vehicle’s drive wheels—functioning similarly to a conventional wheeled chassis.
✅ Reliability through passive technology
No electronics, no wiring, no auxiliary engines—only robust mechanical systems based on differentials, pumps, and chains.
