Equipment Overview
The CAT 730 is an articulated dump truck built for off-road hauling across broken, uneven ground, part of Caterpillar’s articulated truck range alongside the 725, 735, 740, and 745. It carries a 28-tonne rated payload and produces 280 kW of gross power, suited to construction sites, quarries, and civil earthworks where a rigid-frame truck struggles with traction or ground clearance.
Power comes from a Cat C13B engine rated at 280 kW (375 hp) gross, with 274 kW (367 hp) net and 2,141 N·m of peak torque at 1,200 rpm. The engine meets U.S. EPA Tier 4 Final, EU Stage V, Japan 2014, and Korea Stage V emission standards. A CX31 six-speed auto-shift transmission drives all three axles, and automatic inter- and cross-axle differential locks help maintain traction on loose or wet ground. The front suspension also oscillates six degrees each way to keep all six wheels planted on rough terrain.
