Hyundai Construction Equipment Americas Inc.’s HL770-9A and the HL780-9A wheel loaders are part of Hyundai’s new 9A product line, all of which meet Interim Tier IV standards and are ideal for aggregate, quarry and truck loading applications. Operators can look forward to many upgrades including more horsepower and fuel efficiency, improved durability and serviceability as well as enhanced operator comforts, according to the manufacturer.
This loader’s introduction follows close behind the HL760-9A wheel loader model, which was introduced earlier this year.
Hyundai’s HL770-9A and HL780-9A loaders are built with electronically controlled, fuel efficient, Cummins Interim Tier IV and EU Stage IIIB engines. The HL770-9A boasts a 297 hp, QSL9 engine, where as the more powerful HL780-9A features a 351 hp, QSX11.9 engine. Both loaders have three engine modes, power mode for heavy duty work, standard mode for general work and economy mode for light duty work, giving operators the utmost flexibility and allowing for full power or reduced fuel consumption depending on the task. The HL770-9A and HL780-9A also are equipped with a fully automatic transmission designed for minimum power loss, improved travel speed and low noise.
The HL770-9A loader has an operating weight of 51,810 lbs. (23,500 kg), a bucket capacity of 5.5 cu. yds. (4.2 cu m) and a bucket breakout force of 47,930 lbs. while its larger counterpart, the HL780-9A, has an operating weight of 66,800 lbs. (30,300 kg), a bucket capacity of 7.1 cu. yds. (5.4 cu m) and a bucket breakout force of 52,360 lbs. For jobs such as loading high-sided trucks or hoppers where a higher dump height is needed, both loaders are available in extended reach (XTD) models.
Hyundai’s two newest 9A wheel loaders have many enhanced features for improved durability. Both loaders are now equipped with a long-life cooling system with relocated cooling fan and radiator designed to resist thermal shock, impulse and vibration.
Operators also will find a redesigned steering cylinder lug and bucket link, made of steel cast, for additional strength and reliability. The new load sensing hydraulic system with a variable displacement piston pump and closed center main control valve is set to provide operators with efficient hydraulic power and additional energy savings. Other improvements include an enhanced axle to provide better driving over variable ground conditions and self-adjusting brakes, which automatically regulate disc clearance.
As always, Hyundai has kept operator comfort in mind with the HL770-9A and HL780-9A models. Visibility has been improved in the newly redesigned, operator’s cab. New rounded front glass and larger door glass will give operators a larger field view while the overall larger cab will provide operators with improved comfort. Both loaders also feature an increased heating and cooling capacity using a fully automatic climate control system to provide optimum air temperature. Other amenities include a tilting and telescopic steering column, adjustable wrist rest for reduced operating stress, roller-type sunshades, heated side mirrors, multiple storage compartments, an AM/FM radio with MP3 interface, USB output and hands-free Bluetooth capabilities. For further convenience, the HL770-9A and HL780-9A are installed with an improved ladder with 20 degree incline, large deep tread and aluminum cast steps making entering and exiting the cab much easier and safer.
An advanced feature of the new 9A loader models is a 5.7 in. touch screen, color monitor. Operators will appreciate the easy-to-read LCD display with a natural movement screen. The monitor also features an integrated load weighing system, giving operators valuable data to help improve work efficiency and prevent overloading. Self-diagnostics, a color rear-view camera, maintenance check lists and start-up machine security are additional features of the LCD monitor making it a versatile and essential device to have on-hand. The display unit is mounted on an adjustable swivel which, can be rotated horizontally and vertically to meet the operator’s preference and to avoid glare.
To ensure profitability, Hyundai has equipped the HL770-9A and HL780-9A loaders with enhanced service features and longer life components. Like all of Hyundai’s equipment, these new models will be equipped with the Hi-mate remote management system in order to prevent any unexpected maintenance or downtime. This system provides operators and dealer service personnel with vital service and diagnostic information on the machine from any computer with internet access. Capabilities of the Hi-mate system include pinpointing the machine’s location, setting work boundaries, identifying working hours and fuel consumption and reporting of any daily maintenance needed.
Servicing is made easier with a tilting transmission and swing-open hydraulic oil coolers for quick access and regular maintenance checks. The HL770-9A and HL780-9A also feature conveniently located oil site gauges and ground line access to fuel and oil filters, grease fitting, fuses, machine computer components and wide open compartments.
