For multiple caterpillar haul-offs:
- Digital controls and separate AC servo drives insure speed stability and optimum pulling force
- Elimination of mechanical linkages to insure equal force distribution
- Overall efficiency improvement
- V-shaped pads vulcanized onto the caterpillars for pipe applications
- Pneumatic cylinders that insure high haul-off forces, even with low coefficient of friction between the haul-off pads and the pipe
