The New Hyundai Construction Tier 4 HL770-9A and HL780-9A Loaders
Once again Hyundai Construction has produced state-of-the-art equipment that can withstand the test of time as well as whatever job-site conditions throw your way. This time it’s the new HL770-9A and HL780-9A wheel loaders — designed with you in mind, if your days include quarry, aggregate or truck loading work.
Hyundai Construction has built numerous upgrades into these wheel loaders, all geared toward giving you increased flexibility on the fly. These machines give you better fuel efficiency without sacrificing power or utility. Both come with electronically controlled Cummins Interim Tier 4 engines, and both are available in extended-reach models.
Vital statistics.

- Bucket capacity: 5.5 cubic yards
HL780-9A:
- 351 hp QSXl11.9 engine
- Operating weight: 66,800 lbs.
- Net power: 2000 rpm
- Breakout force: 52,360 lbs.
- Bucket capacity: 7.1 cubic yards
Advantages everywhere you look.
- You can change engine power and transmission modes on the fly, to get extra strength when you need it but reduce fuel consumption for lighter-duty tasks.
- You can match the clutch cut-off mode to the work at hand.
- Fully automatic transmission minimizes power loss and noise while increasing travel speed.
- The totally redesigned cooling system has a repositioned cooling fan and radiator. The parallel-mounted coolers have non-louvered fins for easier cleaning and service. And the system has been extensively factory-tested for durability against thermal shock and vibration.
- The redesigned, steel cast steering cylinder lug and bucket link are stronger and more reliable.
- A new load-sensing hydraulic system saves energy but puts out more efficient hydraulic power, thanks to its variable displacement piston pump and closed center main control valve.
- Enhanced axles offer smoother travel over uneven ground.
- Self-adjusting brakes automatically compensate for disc wear, improving performance and stretching service intervals.
A better day at the “office.”
Hyundai Construction knows operator comfort isn’t a luxury — conveniences make the work go faster and more productively. So the roomier cab offers:
- Rounded front glass and larger door glass for broader visibility.
- Fully automatic climate control.
- Tilting, telescopic steering column.
- Adjustable wrist rest.
- Roller-type sunshades.
- Heated side mirrors.
- Multiple storage compartments.
- AM/FM radio with MP3 interface, USB output and hands-free Bluetooth capability.
- Easier, safer access with a 20-degree incline ladder that has large, deep tread and cast aluminum steps.
- An optional ride control system uses a shock-absorbing accumulator to cushion the boom cylinders, offering greater operator comfort. It also reduces material loss.
Convenient rotational switches for engine power, automatic transmission shift timing and clutch cut-off. And a 5.7-inch touch-screen color monitor with rear-view camera enables at-a-glance monitoring of work in progress as well as diagnostics. The monitor is swivel-mounted so it rotates horizontally and vertically for glare-free viewing. Operators can tailor the display to match their personal preferences.
Bottom-line conscious maintenance.
Longer-lasting components and longer service intervals save labor and reduce down time. Service is a snap, with tilting transmission and swing-open hydraulic oil coolers, conveniently located oil site gauges and ground-level access to fuel and oil filters, grease fittings, fuses, machine computer components.
And the Hi-mate Remote Management System can be accessed from any computer that has internet access, providing data about the loader’s location, working hours, fuel consumption and daily maintenance needs.
The HL770-9A and HL780-9A give you all the advantages. Increased productivity. Increased comfort and convenience. Increased fuel efficiency. You’ll want to make space at your yard for one of these latest additions to the Hyundai Construction 9A series of wheel loaders.
