Equipment Overview
The CAT 740 is an articulated dump truck built for off-road hauling across broken, uneven ground, part of Caterpillar’s articulated truck range alongside the 725, 730, 735, and 745. It carries a 36.3-tonne rated payload and produces 335 kW of gross power, suited to quarrying, mining support, and large-scale civil earthworks where a rigid-frame truck struggles with traction or ground clearance.
Power comes from a Cat C15 engine rated at 335 kW (449 hp) gross, with 324 kW (434 hp) net and 2,320 N·m of peak torque at 1,200 rpm. In this Asia-Pacific market build, the engine is offered in a Brazil MAR-1 configuration equivalent to U.S. EPA Tier 3 and EU Stage IIIA, or in a noncertified configuration equivalent to U.S. EPA Tier 2 and EU Stage II. A CX38 transmission auto-shifts through nine forward and two reverse gears, driving all three axles, and retarding comes from both the engine compression brake and a hydraulic retarder.
