Articulated Dump Truck Showcase

DoosanDoosan

Doosan Infracore Construction Equipment has launched the new DA40 ADT, the first in a new family of Doosan ADTs offering increased engine power and torque, higher payloads, lower fuel consumption, enhanced operator comfort and faster travel speeds. Incorporating more than 40 years of expertise in the ADT market, the new Doosan ADTs are optimized for extreme performance. The exceptionally agile undercarriage, designed to ensure that all six wheels are in permanent contact with the ground, means that Doosan articulated dump trucks can operate on very rough and soft terrain on construction sites such as road projects and mass excavation hauling as well as in mining and quarrying applications. Powered by a six-cylinder, Tier 4 Interim-compliant diesel engine with a net power output of 490 hp at 2,100 rpm, the new DA40 offers an 11 percent increase in engine power compared with the previous MT41 model.

Designed and built in Davenport, Iowa, the E-Series ADTs feature a John Deere PowerTech 13.5-L Tier 4 Interim engine with three power levels based on the model — 422 net hp (370E), 443 net hp (410E) and 481 net hp (460E). The 460E is North America’s largest ADT, says the company. All models come equipped with a purpose-built ZF transmission that includes a high capacity retarder, eight forward gears and four reverse gears. In addition, the John Deere hauler axles are designed for heavy-duty applications and include on-the-fly differential locks, outboard planetaries and each axle is independently pressure lubed and filtered. The E-Series axles use internal wet disc brakes that utilize independent cooling circuits. The E-Series also allows true ground level servicing to simplify daily maintenance and overall serviceability. All daily service can be completed from the ground.

KomatsuKomatsu

Komatsu America’s HM400-3 articulated truck is powered by a Komatsu SAA6D140E-6 engine with 469 net hp and is EPA Tier 4 Interim certified. The truck features a maximum gross vehicle weight (GVW) of 162,569 lbs., hauling up to a 44.1-ton payload at its maximum ground speed of 34.7 mph. Its low 10-ft, 5-in. loading height easily matches with 40- to 60-ton hydraulic excavators or 5.5- to 7.5-cu yd wheel loaders. The HM400-3 is equipped with the Komatsu Traction Control System (K-TCS), which automatically provides optimum traction when operating in soft ground conditions. As ground conditions worsen, speed sensors located on four wheels detect tire slippage, and automatic application of the inter-axle differential lock occurs. The HM400-3 comes standard with Komatsu CARE, which includes complimentary factory scheduled maintenance for 2,000 hours or the first three years (whichever occurs first).
