The Caterpillar 631E is a self-propelled wheel tractor scraper used in earthmoving, mining, road construction, and large-scale site preparation. As part of Caterpillar's scraper lineup, the 631E is designed for high-volume material loading, hauling, and spreading over medium to long distances. It typically features a twin-engine or tractor-scraper configuration depending on version and application, with a large bowl capacity, heavy-duty frame, and hydraulic controls for efficient cut, load, transport, and dump cycles.
