Terex Trucks’ TA300 hauler – more fuel
efficient than ever before
Simple to operate and easy to maintain, the TA300 is a proven performer that delivers low total cost of ownership and high productivity. Since August, the machine has incorporated a new transmission that leads to a 5% improvement in fuel efficiency.
The TA300 articulated hauler from Terex Trucks is a popular choice on quarries, construction sites and infrastructure developments. The 28 tonne (30.9 ton) workhorse offers a heaped capacity of 17.5 m3 (22.9 yd3) and is powered by a Scania DC9 engine, which develops gross power of 276 kW (370 hp) and a maximum torque of 1880 Nm (1387 lbf ft). The TA300’s fuel efficient engine range is globally emissions compliant and meets the requirements of EU and North American legislation without the need for a diesel particulate filter (DPF). This is achieved via the latest generation selective catalytic reduction (SCR) technology, combined with exhaust gas regeneration (EGR) and a variable geometry turbo (VGT).
Product improvements
Since August 2018, the TA300 has been manufactured with the latest EP320 transmission. The updated machine now delivers a 5% improvement in fuel efficiency, a 5 km/h (3.1 mph) increase in speed to 55 km/h (34 mph), an extended maintenance period and enhanced performance when compared with the previous model. All of this means that customers can be more productive, achieving faster cycle times, lower cost per tonne and reduced carbon emissions.
The TA300’s new transmission comes with eight forward gears as well as four reverse gears, higher overall gear ratio spread, equal ratio steps between gears, and optimized gear shifting with partial load shifts. These features mean that the upgraded TA300 offers lower fuel consumption with smoother gear shifting and thereby higher levels of operator comfort. The TA300 also now comes with long life transmission fluid, increasing the length of time between oil maintenance intervals from 1,000 to 4,000 hours.
High power, maximum comfort
The TA300 is equipped with true independent front suspension as standard, further enhancing operator comfort and enabling excellent traction control and maximum productivity, even in challenging conditions. The TA300 also has fully enclosed, oil- cooled, multi-disc brakes at all six wheels. These are supported by both the engine brake and the transmission retarder, giving the operator superb control and increasing safety and stability while providing a low cost of operation.
Helping to ensure high levels of operator comfort and productivity, the TA300 has a spacious, ergonomically designed cab with pressurized properties, which ensures operators are comfortable when behind the wheel. Acoustic insulation helps to minimize noise levels inside the cab while a high performance and easily adjusted heating, ventilation, and air conditioning (HVAC) system ensures a stable temperature. Other features that help to deliver a comfortable work environment include a tilt/telescopic steering wheel, an adaptive air suspension operator’s seat with adjustable armrests, anti-vibration mounts for the engine and cab, and cushioned stops on the steering cylinders.
For safe, easy servicing, the TA300 has ground level test points, a fully tilting cab, an electronically raised hood and a full suite of on-dash diagnostic and machine health check readouts which help to maximize uptime.
