TEREX TOPS OFF ARTICULATED TRUCK LINE New 40 ton class TA400 articulated truck largest in construction equipment lineup BY DAWN M. GESKE New from Terex is the TA400 articulated truck. The truck sits in the 40 ton class and is the new top end of Terex’s construc- tion division truck lineup. It is not part of the mining operation that Terex is selling to Bucyrus International. Terex has a healthy articulated truck lineup with six models rated 300 to 450 hp and with payloads from 25 to 41. 9 tons. The new TA400 is the largest articulated truck Terex pro- duces, filling out the top end of the company’s lineup with a heaped capacity of 30. 3 cu.yd. Typical applications for the truck include sand and gravel quarries, coal mines and road construction projects. Terex said it designed the TA400 articulated truck with a maximum rim- pull and gradeability for negotiating inclines, as well as a large body capacity with low body weight to max- imize load size and retention. “Our articulated trucks are well known for their productivity and dura- bility, and the new TA400 is our tough- est performer yet,” said Ken Emmett, Terex product manager. “We have rig- orously tested this truck under the most extreme conditions around the world — it has proven through all the trials to keep our customers’ produc- tivity high, fuel consumption low and cycle times short. The TA400 is de- signed to offer Terex customers the best cost-to-value ratio.” Powering the TA400 articulated truck is a Tier 3 Detroit Diesel Series 60 diesel engine rated 450 hp. The in- line engine has six cylinders, a 14 L displacement, is turbocharged with air- to-air charge cooling and has direct injection and electronic engine man- agement. Maximum engine torque is 1548 lb.ft. An Allison HD4560 transmission with integral retarder is mounted directly to the engine. The transmission is fully automatic with planetary gearing and electronic control of the six forward and one reverse gears. Ground power is transferred through a remote-mounted, two-speed transfer gearbox, taking power from the transmission and feed- ing it via a lockable differential to front and rear wheels. The TA400 articulated truck’s 6x6 configuration integrates three axles in a permanent all-wheel drive with dif- ferential coupling between each axle to prevent driveline wind-up, said Terex. The heavy-duty axles have full floating axle shafts, outboard plane- tary reduction gearing and automatic limited slip differentials in each axle. The leading rear axle incorporates a through-drive differential to transmit drive to the rear-most axle. Top travel speed on the truck is 37. 3 mph.
