Model History and Information: The Cat 775E is an off-highway rigid dump truck rated for a nominal payload of 70 tons (63.5 tonnes), a productive hauler in quarrying and mining operations. It is powered by a Cat 3412E twelve-cylinder diesel engine producing 730 hp (544 kW) net at 2,000 rpm, using a four-stroke design tuned for efficient combustion. Depending on body configuration, the 775E carries a flat-floor body of 54.3 cubic yards (41.5 cubic meters) heaped or a dual-slope body of 42.8 cubic yards (32.7 cubic meters) struck, and Caterpillar matched it with loaders such as the 988G for a five-to-six-pass loading cycle. Fast dump cycles, with a 9.5-second body raise time, are aimed at keeping the truck-loader pairing productive.
