Hyundai Construction Equipment Americas launched the HA30 and HA45, 30- and 45-ton articulated dump trucks, marking the company’s entrance to the articulated truck market.
The HA30 has a 16.8-m3 heaped body capacity that rises to 17.8 m3 when fitted with a tailgate. The larger HA45 offers a 24.4-m3 heaped capacity, rising to 26 m3 with a tailgate.
Tier 4 Final Scania diesel engines power both trucks. The HA30 uses a 5-cylinder, 9.3-liter DC9 turbocharged diesel, producing 276 kW and 1,876 Nm of torque. The larger HA45 uses a 6-cylinder, 12.7-liter DC13 diesel engine, producing a maximum 368 kW and 2,476 Nm of torque.
Both engines drive through eight-speed ZF automatic transmissions. The torque converter has lockup in all gears, reducing fuel consumption and increasing efficiency.
The HA30 and HA45 are built around a full-time six-wheel drive concept, with front and rear limited slip differentials and a longitudinal differential that can be manually locked, for maximum drive and traction on difficult terrain. They have a compact chassis design to aid maneuverability, with a sloping rear frame and a front-mounted differential integrated into the ZF transmission, allowing for a shorter front-frame section.
Self-leveling hydro-gas suspension on the front axle further supports a comfortable ride, delivering maximum tractability in tough ground conditions.
The turning ring is mounted in front of the chassis articulation point, resulting in an equal weight distribution to the front wheels in all driving situations for increased stability and traction.
Tandem reduction gearboxes on the two rear axles enable maximum oscillation of the rear axles to maintain ground contact on rough terrain. The single, central differential increases ground clearance beneath the truck. Oil-cooled wet disc brakes achieve an extended service lifetime of up to 15,000 hours. A hydraulically activated mechanical parking brake holds the machine when stationary.
Both dump bodies can be optionally heated by the engine exhaust gases to prevent freezing and sticking of materials when operating in colder temperatures.
With the most spacious ROPS/FOPS cab on the market, the Hyundai ADT features an ergonomic layout to the controls, a high-quality air-suspended operator’s seat, an internal sound level of just 72 dB(A), MP3 and Bluetooth-compatible radio, USB charger, all-round safety rails, and a footrest, the company said. Interior cab storage includes room for an optional cool/hot box and 12-V power sockets for operator phones and other accessories. Full-cab climate control is standard on both models for maximum comfort throughout the working day.
Hyundai’s Hi-Mate telematic monitoring system is standard, with satellite and GSM connectivity, to reach the most inaccessible construction and mining sites across the world.
