Tracked mini excavators

June 20, 2024

HD Hyundai Construction Equipment North America has introduced four new models to its HX-A series of compact hydraulic excavators.

The new additions: the Hyundai HX17AZ, HX27AZ, HX55ACR, and HX60A excavators - fill in the company’s line of compact excavators, the first models of which debuted last year at the CONEXPO 2023 tradeshow. The Hyundai HX-A series compact excavator line now includes eight models.

The four new models all feature low-emission engines that are Tier 4 Final compliant. The Hyundai HX17AZ excavator is powered by a Kubota D902 diesel engine with a net power rating of 16.0 hp (11.9 kW), while the HX27AZ features a Kubota D1305 engine rated at 24.4 hp (18.2 kW). The HX55ACR uses a Yanmar 4TNV86CT engine that delivers 47.6 hp (35.5 kW), and the HX60A employs a Hyundai DM02VB engine rated at 63.0 hp (47.0 kW) at 2,400 rpm.

The smallest of eight HX-A series compact excavators, the new Hyundai HX17-AZ features a zero tail-swing design. It is available in a canopy-only configuration.

Both the HX17AZ and HX27AZ models are true zero tail-swing machines for working in confined or busy spaces. The HX55ACR is a compact-radius model.

The HX55ACR is equipped with a standard load-sensing hydraulic system that reduces wear and tear on hydraulic components while helping to ensure reliable performance and efficiency, simplified operation, and reduced fuel consumption.

The HX17AZ and HX27AZ models feature conventional open-center hydraulic systems. Standard adjustable hydraulic flow control through the cluster on all four models lets the operator easily set the optimum flow range for multiple attachments and switch between them using a two-way diverter valve that directs hydraulic flow to either of two attachments simultaneously.

All four models feature a five-inch full-color LCD monitor. Standard boom, arm and bucket cylinder guards protect the digging end of the machine. Other standard features include a hydraulic quick coupler and an integrated utility lifting hook.

The HX55ACR and HX60A models offer standard blade float, which automatically forces the blade down to ensure consistent backfilling and grading. Auto engine idle - also standard on the HX55ACR and HX60A - optimizes fuel efficiency by reducing engine speed when the excavator is not in use. Standard auto-shift travel speeds allow a seamless transition between high and low travel speeds for increased efficiency and productivity in moving the excavator around the job site.

The HX17AZ has an operating weight of 4,370 lb (1,980 kg), a dig depth of eight feet (2.44 meters), and a bucket breakout force of 3,668 pounds per foot (1,664 kilograms per foot). The HX27AZ has an operating weight of 6,140 lb (2,478 kg) in its canopy configuration, a dig depth of eight feet 10 inches (2.7 m), and a bucket breakout force of 4,613 lbf (2,093 kgf).

The HX55ACR has an operating weight of 12,600 lb (5,715 kg), a dig depth of 12 feet 8 inches (3.86 m), and a bucket breakout force of 8,354 lbf (3,789 kgf). The HX60A in its standard cab configuration has an operating weight of 13,580 lb (6,160 kg), a dig depth of 12 foot-four inches (3.77 m), and a bucket breakout force of 9,461 lbf (4,292 kgf).
