Hyundai launches two articulated dump trucks from: Hyundai Construction Equipment Americas Inc.

Hyundai Construction Equipment Americas has announced its entry into the articulated dump truck market with two new models – the HA30 and HA45 articulated dump trucks – targeting the popular 30 and 45 ton segments. The first of the new ADTs are now available to order through Hyundai’s North American network of authorized dealers.

With rated payloads of 28 and 41 tonnes respectively, the HA30 and HA45 articulated dump trucks are a suitable haul truck for Hyundai’s largest crawler excavators and wheel loaders. Designed for high-volume earthmoving projects, highway construction, and mining and quarrying operations, Hyundai articulated dump trucks provide maximum drive and traction in tough jobsite conditions, maintaining customer productivity throughout. of the year.

“Hyundai is excited to enter the ADT market to better serve its aggregate and infrastructure construction customers,” said Mike Ross, senior vice president of CE sales, parts and service, Hyundai Construction Equipment Americas. “Our new ADT models are the first collaborative results of the combined design, engineering and manufacturing expertise of Hyundai Construction Equipment and Hyundai Doosan Infracore.”

The Hyundai Heavy Industries Group bought the Doosan business in 2021, which now operates – together with Hyundai Construction Equipment – as a separate division within Hyundai Genuine. While retaining their respective management and dealer network structures, the two divisions plan for further integration in R&D, design, engineering, supply and manufacturing.

Articulated transport

The new Hyundai HA30 and HA45 trucks are built around a permanent six-wheel drive concept, with front and rear limited-slip differentials and a longitudinal differential that can be manually locked, for maximum ride and traction in difficult terrain .

The trucks have a compact frame design, to aid handling, with a sloping rear frame and a front-mounted differential integrated with the ZF transmission, allowing for a shorter front frame section. This results in the smallest turning radius in the vehicle class and stability. The self-leveling hydro-gas suspension on the front axle additionally promotes a comfortable ride, providing maximum maneuverability in difficult ground conditions.

The swivel ring is mounted in front of the chassis pivot point, allowing even weight distribution to the front wheels in all driving situations, for increased stability and traction.

Tandem final drives on both rear axles allow maximum rear axle oscillation to maintain ground contact on rough terrain. Unique center differential increases ground clearance under the truck. Oil-cooled wet disc brakes achieve extended life of up to 15,000 hours. A hydraulically operated mechanical parking brake keeps the machine stationary. The trucks are supplied with a grade indicator, with rollover protection and a Body Over Center of Gravity feature, to assist drivers when unloading and operating on rough terrain.

The HA30 has a cambered body capacity of 22 yd3 (16.8 m3), which increases to 23.3 yd3 (17.8 m3) when equipped with a tailgate. The larger HA45 offers a heap capacity of 32 yd3 (24.4 m3), increasing to 34 yd3 (26 m3) with a tailgate. Both tippers can be optionally heated by engine exhaust to prevent freezing and sticking of materials when operating in colder temperatures. Internal wear plates are available as an option when working in heavy, hard rock applications.

Proven powertrain

Scania Tier 4 Final diesel engines power both trucks. The HA30 uses a DC9 9.3-liter five-cylinder turbocharged diesel engine, producing 375 hp (276 kW) and 1,876 Nm of torque. The larger HA45 uses a 12.7-liter six-cylinder DC13 diesel engine, producing a maximum of 500 hp (368 kW) and 2,476 Nm of torque.

Both engines are driven by eight-speed ZF automatic transmissions. The torque converter locks up in all gears, reducing fuel consumption and increasing efficiency. Ground level service points are designed for maximum efficiency and improved safety. The engine hood tilts forward to access filters and fill points, while the entire cab structure can also be tilted towards the rear of the truck, to allow access for repairs and maintenance. ‘maintenance.

Hyundai’s Hi-Mate telematics monitoring system is standard, with satellite and GSM connectivity, to reach inaccessible construction and mining sites around the world. This allows remote monitoring of productivity, fuel consumption, system alerts and maintenance status, reducing unplanned downtime and improving fleet utilization.

Comfort and protection

With the most spacious ROPS/FOPS cab on the market, the Hyundai ADT features an ergonomic control layout, air suspension operator seat, internal noise level of only 72 dB(A), MP3 and Bluetooth compatible radio , a USB charger , versatile safety rails and a footrest. Interior cab storage includes space for an optional cooler/warmer and 12V power outlets for operator phones and other accessories. Full cab air conditioning is standard on both models for maximum comfort throughout the workday.

A comprehensive control panel provides an integrated payload indicator to prevent overloads and record productivity. Diagnostic functions are included in the monitoring system, and the operator can remotely check hydraulic and transmission oil levels from the cab. A grade indicator ensures the truck is driven safely within its limits, while an integrated rear-view camera and large mirrors provide all-round visibility when reversing under a shovel or in the dump area.
