Terex celebrates birthday with truckloads of ideas

Terex has launched several new products to coincide with this, its Golden Anniversary Year.
The list is headed up by the TR70, a 65t capacity which is a new expression of Terex's design strategy. From its softly aggressive front to its spacious air-conditioned cab, it makes many other dumptrucks look old-fashioned.
It's powered by a 567kW (torque 3118Nm@1, 200rpm) Detroit Diesel vee-12 driving through an Allison MT6600R six-speed automatic box with soft-shift, lock-up in all speeds and a built-in hydraulic retarder.
Foundation brakes are dry-disc front and oil-cooled multi-disc rear with full hydraulic operation and a nitrogen accumulator to give instant response. Parking brakes are spring-on power-off for safety.
The power steering feeds off the same hydraulic circuit and an accumulator gives uniform steering regardless of engine speed. It also provides two turns of lock-to-lock steering in an emergency.
The 29m3 (struck) capacity V-shaped body has a high-hardness steel floor and is hoisted by twin in-frame cylinders powered from a separate tipping circuit-body raise, time = 13 seconds, body lower = 11.5 seconds. The body is standard exhaust-heated.
The TS14G is the latest incarnation of Terex twin-engined scraper technology. It's a derivative of the TS14F which was only introduced at Conexpo '99. The new model features the Funk transmission as before but has the newest version of the Detroit Diesel series 40 engine with electronic control and 'drive by wire' throttle. Combined power is 255kW.
The cab is also new with full ROPS/FOPS rating, and the bowl now has a power-down apron for more accurate control over loading rates. The cab is upgraded with a broad family likeness to both rigid and articulated dumptruck cabs.
At the same time Terex has made major changes to its TA25 and TA30 ADTs by opting for a lower bonnet line (by 175mm) with a new one-piece GRP hood moulding, instead of the previous two-piece steel component.
Engine bay access is much better and the operator's sightline is improved, especially close-up to the front.
A new crossflow radiator is mounted lower, with its drive also set lower on the engine front gear housing. Fan diameter is increased to 762mm and the transmission oil cooler is now mounted directly behind the bumper.
A single-gear pump for the hydraulic steering and hoist system replaces the previous two-pump set-up. A ground-driven secondary steering pump replaces the previous accumulator-fed system in an emergency. Steering system pressure is up by 69bar to 241bar and means quicker response, especially at lower engine speeds.
An additional calliper on each of the front disc brakes increases braking power by one-third, and a dual-circuit foot valve means 50%of braking is available in an emergency - say when a hose bursts.
