Hyundai 35.5-ton excavator matches engine power, hydraulic flow to required digging force

HD Hyundai Construction Equipment North America has added the 258 net hp (192 kW) HX355A LCR, a 35.5-ton compact-radius excavator, to its lineup of full-sized crawler excavators.

With an operating weight between 78,483 and 79,807 pounds (35,600 and 36,200 kilograms, respectively), the HX355A LCR fits between the Hyundai HX350A and HX380A conventional-swing excavators. The compact-radius design allows the excavator to perform a multitude of jobs within confined areas typically reserved for smaller machines.

"When contractors and other equipment users need an excavator that delivers serious power with a relatively compact footprint, the Hyundai HX355A will serve them well," said Joe Hodges, product manager at HD Hyundai CE North America. "In the case of this compact-radius model, the cab remains inside the tracks during front or rear operations and extends a minimal four inches outside the tracks during side operations." 

The HX355A LCR is typically equipped with a one- and three-quarters cubic yard (1.34 cubic metre) bucket and features an 18-inch (475 millimetre) ground clearance. Hyundai also offers an 11-foot 10-inch (3.6 metre) dozer blade as an option. Adding a dozer blade to a 35-ton excavator adds versatility that is particularly useful, according to Hodges, in construction and landscaping projects where digging and leveling are required.

"With a dozer blade, operators can push and move materials more efficiently, which is especially beneficial for tasks like backfilling trenches, leveling terrain or pushing debris," Hodges said.

The HX355A LCR has four selectable power modes and a one-touch power boost for better control over machine power and efficiency. The HX355A also comes with an integrated SPC (smart power control) system. SPC uses sensors and software to monitor the excavator's workload in real-time. Based on this data, it automatically adjusts engine power and hydraulic flow to match the required digging force. This ensures that the excavator operates efficiently without unnecessary fuel consumption or strain on the engine.

"SPC helps keep the excavator running longer," Hodges said, "because it keeps the machine operating within optimal power ranges, which reduces wear and tear associated with overloading or inefficient operation. This extends the life of critical components, including the engine, hydraulic system and attachments."

Hodges described the Hyundai HX355A LCR as a full-featured machine.

"Hyundai is known for delivering value by outfitting our excavators with more standard features," Hodges said. "Among the standard features on this model are five years of Hyundai's proprietary Hi MATE telematics system, heated air-suspension seat, an 8-inch automotive-style interactive display monitor, remote ignition and so much more. Making these types of features standard equipment helps keep operators safer, more comfortable and more productive, which keeps owning and operating costs down."
