The type of equipment best suited for hauling large rock fragments or masses of slate/shale is the _______.

• A. Dump Trailer
• B. Wheel Loader
• C. Scraper
• D. End-Dump Truck

Answer: (D)

Heavy, bulky rock like large fragments or slate/shale needs a hauling method that can carry a big load and unload quickly and cleanly. An end-dump truck fits this perfectly because its bed is built for high payloads and it unloads by tilting the rear, dumping the material straight onto the stockpile or ground with gravity. This setup handles irregular rock pieces well and works well on rough jobsite roads typical of quarries and construction yards. Dump trailers don’t match the payload or discharge efficiency for such heavy material, and wheel loaders or scrapers are mainly for moving material around the site rather than hauling large masses over a distance to a dump or stockpile.
