You are a contractor and and you would like to utilize Caterpillar 637G scrapers for an upcoming project. The project's haul route is 2,000 lf each direction, the elevation of the cut is 1,443 ft and the fill is 1,560 ft. The scrapers will work in tandem and load in the push-pull arrangement. You are expecting 1.5" of tire penetration on the haul routes and will utilize the total operated empty and loaded weights that Caterpillar lists for that machine in their product brochure.
