The machines are the well-accepted Doosan models built in Norway and now being offered in Hyundai branding following the tie up between the firms.
The firm claims equal weight distribution due to the sloping rear chassis frame design, which is said to deliver stability by distributing more load towards the centre of the machine and resulting in a low centre of gravity. The machines also have the proven tandem rear axle bogie configuration, which is said to offer a higher degree of articulation than competing designs and optimises ground contact to maximise traction. The machines also feature the articulation joint turning ring mounted close to the front axle, which further helps to equalise load distribution between the front to rear and across the front axle during steering.
The trucks are powered by Stage V-compliant Scania diesels. The HA30A uses a five-cylinder, 9.3litre, DC9 turbocharged diesel, developing 276kW and 1,876Nm of torque. The larger HA45A employs a six-cylinder, 12.7litre DC13 diesel engine, producing 368kW) and 2,476Nm of torque.
Both engines drive through eight-speed ZF automatic transmissions, with integrated retarders. The torque converter has lock-up in all gears, reducing fuel consumption and increasing efficiency. Fuel, AdBlue diesel engine exhaust fluid and a standard auto-lube greasing system can all be easily accessed from ground level. The engine canopy tilts forward for access to filters and fill points, while the cab structure can be tilted to provide access for repair and maintenance.
Hyundai’s Himate telematic monitoring system is fitted standard, with satellite and GSM connectivity. This allows customers to monitor productivity, fuel consumption, system warning and maintenance status remotely, reducing downtime and improving fleet utilisation.
