Doosan Moxy 41-Ton Articulated Dump Truck Combines Power, Stability and Traction

The Doosan Moxy MT41 articulated dump truck offers high horsepower per ton of loaded weight, a free-swinging rear tandem bogie and a special articulation system for enhanced productivity and driving performance.

The MT41 is powered by a 444-hp (331 kW), Tier III compliant Scania diesel engine that provides a power-to-weight ratio of 6.38 hp (4.7 kW) per ton. It has a payload capacity of 82,010 lbs. (37,199 kg).

The turning ring on the MT41 is located in front of the articulation joint, ensuring equal weight distribution to the front wheels at all times, even in maximum turns. This results in easier steering and less front tire wear. The MT41 also features independent front-wheel suspension for better traction and operator comfort.

Permanent 6-wheel drive provides traction in rough terrain. The free-swinging rear tandem bogie allows the rear wheels to maintain ground contact at all times. Only one differential lock/limited slip differential is required on the rear axles, resulting in less driveline and tire wear, according to the manufacturer.

The sloping body ensures a low center of gravity and enhanced weight distribution, further enhancing the stability of the MT41 and providing fast and easy tipping for increased productivity.

A fully automatic transmission provides six forward speeds and three reverse. Top speed is 32.9 mph (53 kmh) in high range and 21.1 mph (34 kmh) in low range.

Wet disk brakes provide more efficient braking under load, even in very adverse conditions such as deep mud and water. Because they are fully encased in oil, brake discs also last longer, reducing maintenance costs.

The comfortable, air-conditioned cabin features an air suspension seat, low noise and vibration levels and good visibility, due to the sloping front hood. The “tip-tronic” gearshift allows the operator to run the truck in both automatic and manual gears for the smoothest possible gear-shifts and momentum.
