Any idea how long the truck exchange time is when using a scraper? Well, actually it's zero❗ Scrapers can load, haul, spread and can even compact the material while dumping, so you don't need a truck. It's an all-in-one machine that provides very efficient production. Scraper loading time should be around 30 seconds; loading and dumping are done on the go. | Caterpillar Demonstration and Learning Centers
