Hyundai strengthened its excavator lineup with the addition of two new mid-range models: the 16-ton HX160A L and the 18-ton HX180A L.
The new machines come with Tier 4 Final/EU Stage V, B4.5 Cummins diesel engines that eliminate the need for exhaust gas recirculation (EGR) for emissions control while at the same time offering a 5% improvement in fuel efficiency, the company says. Horsepower has increased 13% (to 155 gross hp) and the all-important torque output muscles up 27%.
A new lifting mode improves fine hydraulic control by using engine rpm reduction, power boost action and an optimized hydraulic pump flow rate that matches power to the machines’ working demands, the company says. Hyundai calls this their Electric Pump Independent Control, or EPIC. A redesign of the main control valve and efficient hydraulic hose routing minimize energy loss within the system.
The P mode is designed for leveling and truck loading, and fine swing control smooths out the movement of the boom at the stop-start of the swing motion. The boom lift speed compared to swing speed is operator selected. The dipper arm can also be fine-tuned by activating and deactivating the arm regeneration function. And once you’ve got it dialed in, you can save your machine settings through Hyundai’s new “Key On Init” work mode that applies your preferred settings on start-up.
Both machines can be spec’d with a range of track pads from 1.6 feet to 2.3 feet. The HX180A L gives you the option to spec 2.62-foot track pads for low ground pressure and stability. The standard monoboom reaches up to 31 feet and digs to 21.4 feet. Or you can choose a factory-built, two-piece boom that reaches 29.9 feet and digs to 18.6 feet.
