Caterpillar says its new 70-ton-payload (63.5 metric ton) 775G off-highway truck combines new drive train strategies and a 5% power increase to give it enhanced efficiency over its predecessor. To balance fuel savings and production, two different economy shift mode selections enable the user to tailor performance to the needs of the application, while advanced control systems also integrate the optional engine compression brake with Automatic Retarder Control to enable faster downhill travel and reduced cycle times―without increased fuel consumption. To meet Tier 4 Final emissions regulations in the U.S., the Cat C27 ACERT engine includes a NOx reduction system and diesel oxidation catalyst. The system requires the use of ultra low sulphur diesel fuel and does not use a diesel particulate filter.

The 775G also features a new cab design. The operator seat is now in the center of the cab, which provides more space for the operator, and the cab has access and egress from either side with stairs illuminated by LED lights. The 775G has a ground level electrical service center and diagnostics port on the front bumper. Cat’s VIMS data collection system is standard equipment on the 775G, and an optional VIMS service light on the front of the truck will indicate any machine event that affects performance. Fluid level indication and fluid fill ports are grouped for efficient service, and fluid filters are grouped. Filter service intervals for steering, hoist/brake, and transmission/torque converter have been increased from 500 to 1,000 hours.
