Bulldozer/Research Development

Overview

Research pertaining to the Bulldozer.

Industry Standards

• Caterpillar D3 - 30,000 lb, 63 hp - drawbar power?

_______________________________________ Well designed bulldozers develop a tractive force of 80-90% of their weight under favorable soil conditions. Tractive force minus force needed for bulldozers rolling resistance gives drawbar pull. Bastelmike 20.1.2012

Design Proposals

Wide with two Power Cubes

Motor Coupling

• http://ustsubaki.com/pdf/brochures/L10794_coupling.pdf

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.
