Video | HD Hyundai unveils next-generation HX excavators at ConExpo

The new machines feature fully electrohydraulic (FEH) controls, which HD Hyundai claims help to increase productivity by at least 22% while allowing the machines to run more smoothly.

They are powered by HD Hyundai’s DX Series engines, which make the new machines nearly 10% more fuel efficient.

The five new models, the HX230, HX260, HX300, HX360 and HX400, are rated at 186, 226, 277, 300 and 336 net hp (139, 169, 206, 224 and 251 kw), respectively.

Operating weights are 23,705kg; 26,370kg; 33,020kg; 37,060kg and 41,840 kg respectively, and standard bucket capacities ranging from 1.2 yd3 (0.92 m3) to 2.66 yd3 (2.03 m3).

Hyundai said it plans to introduce a sixth Next Gen model to North America, the HX210, later this year.

All Hyundai models feature joystick steering, spring-strength adjusted lever controls and an optional straight-travel pedal.

They also have larger-capacity, heavy-duty buckets and arms as standard. An optional onboard weighing function estimates and displays the weight of objects in the bucket to enable calculating trucking costs and shipping volumes onsite.

Hyundai has upgraded operator comfort features, including making standard a wider, heated/cooled seat and improved venting for exceptional climate control.

And replacement intervals for engine oil, engine filters, and fuel filters have been extended from 500 to 1,000 hours when owners and fleet managers use CK-4 engine oil.

Coolant replacement intervals have been extended from 2,000 to 6,000 hours.

The new machines also come with five years of Hyundai Connect, the upgraded version of Hyundai’s proprietary HiMate remote management system, free of charge.

Other standard technologies on the Next Gen HX excavators include Equipment Health Monitoring, the e-boundary safety and productivity feature that can warn the operator as they approach preset boundaries and a white noise alert that uses a wideband frequency, which dissipates quickly and reduces noise complaints, according to HD Hyundai.

Optional technologies include 330-degree advanced detection to the sides and rear of the machine with visual and audible warnings to alert the operator and slow or stop the machine if an object enters the warning zone.

And Smart Around View Monitoring (SAVW) works off six cameras and uses AI to detect people passing or working around the machine during operation.
