Hyundai Construction Equipment has added its HL770-9A and HL780-9A wheel loaders to its 9A product line. The new machines feature upgrades to horsepower, fuel efficiency, durability, serviceability and operator comfort.

A Cummins QSL9 Tier 4 Interim engine provides 297 horsepower to the HL770-9A, which has an operating weight of 51,810 pounds, a bucket capacity of 5.5 cubic yards and a bucket breakout force of 47,930 pounds. The HL780-9A, which boasts 351 horsepower, is powered by a Cummins QSX11.9 Tier 4 Interim engine and has an operating weight of 66,800 pounds, a bucket capacity of 7.1 cubic yards and a bucket breakout force of 52,360 pounds.

Both loaders are available in extended reach (XTD) models for applications needing a higher dump height.

Both machines have fuel-saving features. The three engine modes–Power, Standard and Economy–allow the operator to adjust fuel consumption to the task at hand, while the machines’ fully automatic transmissions are designed for minimum power loss, improved travel speed and low noise.

Keeping durability in mind, Hyundai equipped both loaders with a long-life cooling system with relocated cooling fan and radiator designed to resist thermal shock, impulse and vibration.

Other durability-enhancing features include a redesigned steering cylinder lug and bucket link, a new load sensing hydraulic system with a variable displacement piston pump and closed center main control valve, an enhanced axle and self-adjusting brakes.

The redesigned operator cabs in HL770-9A and HL780-9A wheel loaders include several features focused on operator comfort. Improvements over previous models include a rounded front glass and larger door glass, as well as an increased heating and cooling capacity.

Cab features 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, hands-free Bluetooth capabilities and a 5.7-inch touch screen, color monitor.

Also included for improved operator comfort is a ladder with 20 degree incline, large deep tread and aluminum cast steps, intended to make entering and exiting the cab easy and safe.

Hyundai also kept service in mind when designing the loaders. Each machine features a tilting transmission, swing-open hydraulic oil coolers, conveniently located oil site gauges and ground line access to fuel and oil filters, grease fitting, fuses, machine computer components and wide open compartments.

The machines are also equipped with the company’s Hi-mate Remote Management System, which allows operators and dealer service personnel to locate the machine, set work boundaries, identify working hours and fuel consumption and receive maintenance reports.
