The Hyundai HA30 and HA45 articulated dump trucks were voted a Top 100 New Product of 2022 Winner by Construction Equipment‘s annual New Equipment and Products Contest. In this industry-exclusive awards program, Construction Equipment’s editors decide on winners that represent the leading edge of innovation, quality, efficiency, and productivity in the construction equipment field today.
With rated payloads of 28 and 41 tons respectively, the HA30 and HA45 articulated dump trucks provide an ideal haul truck match for Hyundai’s larger crawler excavators and wheeled loaders. Designed primarily for high-volume earthmoving projects, highway construction, and mine and quarry operations, Hyundai’s articulated haulers provide maximum drive and traction in the worst site conditions, maintaining year-round productivity for the customer.
The new Hyundai HA30 and HA45 trucks 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.
The trucks 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. This results in the smallest turning radius in the vehicle class and outstanding stability. 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 equal weight distribution to the front wheels for increased stability and traction in all driving situations.
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 life of up to 15,000 hours. A hydraulically activated mechanical parking brake holds the machine when stationary. The trucks are supplied with a gradient meter, with flip-over protection and a Body Over Center of Gravity function, to assist drivers when dumping and operating on rough terrain.
The HA30 has a 22 yd3 (16.8 m3) heaped body capacity, that rises to 23.3 yd3 (17.8 m3) when fitted with a tailgate. The larger HA45 offers a 32 yd3 (24.4 m3) heaped capacity, rising to 34 yd3 (26 m3) with a tailgate. Both dump bodies can be optionally heated by the engine exhaust gases to prevent the freezing and sticking of materials when operating in colder temperatures. Internal wear plates are available as an option when working in applications with heavy and hard rock.
Tier 4 Final Scania diesel engines power both trucks. The HA30 uses a five-cylinder, 9.3-liter DC9 turbocharged diesel, producing 375 hp (276 kW) and 1,876 Nm of torque. The larger HA45 uses a six-cylinder, 12.7-liter DC13 diesel engine, producing a maximum of 500 hp (368 kW) and 2,476 Nm of torque.
Both engines drive through eight-speed ZF automatic transmissions. The torque converter has lock-up in all gears, reducing fuel consumption and increasing efficiency. Ground-level service points are designed for maximum efficiency and improved safety. The engine canopy tilts forward for access to filters and fills points, while the complete cab structure can also be tilted towards the rear of the truck, to provide access for repair and maintenance.
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. This enables remote monitoring of productivity, fuel consumption, system warning, and maintenance status, reducing unplanned downtime and improving fleet utilization.
