Equipment Overview
The CAT 777 is a rigid dump truck built for high-volume ore and overburden hauling in large open-pit mines and quarries, sitting between the CAT 775 and CAT 785 in Caterpillar’s off-highway truck line. It carries a 91.7-tonne target payload and a 63.5 m³ body, delivering 765 kW of gross power, suited to large-scale mining, quarrying, and bulk earthworks where high-capacity wheel loaders or hydraulic shovels keep loading cycles fast.
Power comes from a Cat C32B 12-cylinder diesel engine producing 765 kW (1,025 hp) gross and 683 kW (916 hp) net, with 5,044 N·m of peak torque at 1,200 rpm. The engine meets U.S. EPA Tier 4 Final and EU Stage V emission standards, with a Tier 2 equivalent version available for non-regulated regions. A seven-speed automatic powershift transmission drives the rear axle, coordinated by Caterpillar’s APECS control strategy, with an available traction control system to manage wheel slip on loose or wet haul roads.
