Double Chain Coupler
Motor Coupling
This table indicates that 100-20 double roller chain coupling can accommodate 77,000+ inch pounds of force, or about 5000 pounds of force at a 15 inch diameter of a bulldozer wheel. This indicates 20,000 pounds of pushing force in 4 wheel drive configuration - as a scaling of the LifeTrac design strategy.
