The Caterpillar 615C II is a self-propelled wheel tractor scraper used for earthmoving, site preparation, and material hauling in construction and mining applications. It is designed to cut, load, transport, and spread soil, gravel, and other loose materials efficiently over short to medium distances. The 615C II features a single-engine scraper configuration, articulated steering, and a bowl and ejector system for controlled loading and dumping. Caterpillar built the model for productivity, traction, and operator control in demanding jobsite conditions. It is commonly used in road building, land development, and large-scale grading operations where high-volume material movement is required.
