Terex Trucks has over 70 years’ experience in building tough, reliable articulated haulers.
Trucks for tunnelling projects What makes Terex Trucks’ articulated haulers, the TA300 and TA400, proven performers for the toughest applications?
COTTISH MANUFACTURER TEREX Trucks explains why tough tunnelling projects require extra tough machinery and how its articulated haulers get the job done in challenging working environments.

Maximum uptime The machines working in the tunnel have to follow an intense schedule and usually run around the clock, seven days a week. Any unscheduled downtime can cause delays and increases costs, so machine reliability and availability are important requirements. To ensure maximum uptime, Terex Trucks uses a longlife transmission fluid that extends oil change intervals. The TA300 has a maintenance interval of 4,000 hours and the TA400’s transmission has an oil change interval of 6,000 hours. Terex Trucks has also extended the maintenance life of the actuation hydraulic fluid to 4,000 hours. This does not only increase uptime; the reduction in consumption and disposal of fluids also helps to minimise environmental impact.
Operational safety The machines’ modulating transmission retarder is coupled with an efficient exhaust brake and fully enclosed oilcooled multidisc brakes, to provide high levels of machine
control and operational safety. To ensure safe operations, Terex Trucks haulers are equipped with effective hazard area communications, including indicators for left and right as well as directional lights, often backed up by additional supporting lights. Terex Trucks has over 70 years’ experience in building tough, reliable articulated haulers. The TA300 and TA400 are straightforward machines that get the job done, no matter what.
Strong and fuelefficient engines Thanks to a drivetrain that Is perfectly matched with the engine, Terex Trucks haulers deliver powerful performance and excel in demanding work environments. The TA300 and TA400 are both equipped with Scania engines. The TA300 is powered by a Scania DC9 engine, which develops gross power of 370 hp (276 kW) and a maximum torque of 1387 lbf ft (1,880 Nm), and the TA400’s Scania DC13 engine develops gross power of 331 kW (444 hp) and a maximum torque of 2,255 Nm (1,663 lbf ft). Both the TA300 and TA400 have recently been updated with an EUStage V emission compliant engine and now boast a reduction in fuel consumption of up to 7% (compared to the Stage IV machines). This

improvement is achieved with advanced engine control and effective fuel injections. In combination with its latest upgrade to a highly efficient 8speed transmission, the Stage V TA300 even delivers fuel consumption savings of up to 10%. The TA300 and TA400 come with three stage aspirated air filtration, which provides increased engine protection to lengthen maintenance intervals.
Comfortable working environment Terex Trucks has improved operator comfort and upgraded the cabs of the TA300 and TA400 with a highperformance heating and airconditioning system.
Easy to maintain Both the TA300 and TA400 have a fully tilting cab for easy access, and the electronically raised hood allows technicians to reach the engine service points quickly. “At Terex Trucks, we have over 80 years’ experience in building tough, reliable off highway haulers,” said Paul Douglas, managing director. “This strong hauling heritage is reflected in our products today. The TA300 and TA400 are straightforward machines that get the job done, no matter what.” ■ www.technicalreview.me
