The Caterpillar 631E is a wheel tractor-scraper in Caterpillar's 631 series, designed for earthmoving, haul, and grading applications. As a scraper, it is used to cut, load, transport, and spread material in large-scale construction, mining, road building, and site development work. The 631E typically features a tractor unit and a scraper bowl with apron and ejector system for efficient material handling. It is commonly associated with high-capacity production in medium to large earthmoving operations. The model is recognized for its articulated design, heavy-duty frame, and compatibility with demanding off-road conditions in bulk material movement.
