The Caterpillar 631K is a wheel tractor-scraper used in large-scale earthmoving, mining support, and highway construction. It is designed for high-volume material loading, hauling, and spreading in medium to long-distance applications. The 631K features a twin-engine scraper configuration with a bowl, apron, and ejector system for efficient cut, carry, and dump cycles.
