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. It is commonly used in mass excavation, site preparation, and land development where fast cycle times and high productivity are required. The machine is part of Caterpillar's K Series scraper lineup and is typically paired with a push tractor for loading in tougher ground conditions.
