The TA300 articulated truck from Terex is the only 30-ton hauler that comes standard with a fully independent front suspension system, the manufacturer says. The unit has a 385-hp, Tier 3-compliant Cummins diesel engine, a ZF fully automatic with manual-override transmission and a maximum torque of 1,309 foot-pounds at 1,400 rpm. The truck is designed for quarrying, mining, construction and road maintenance. Oil-cooled, multiple-disc brakes on each axle, designed to provide extended brake component life, reduce service intervals and improve braking performance. A hydraulic transmission retarder is available as an option.
