Hyundai Construction Equipment Americas Inc., a maker of earth moving and material handling equipment based in Norcross, Georgia, has introduced its first attachment product line to the North American market: a 14-model line of hydraulic breakers. The all new HDB series breakers, ranging from Models HDB10 through HDB800, are designed to complement Hyundai’s excavators of all sizes, the company says.
Hyundai’s HDB series breakers offer chisel diameters from 1.6 to 7.9 inches. Operating weights range from 271 to 12,401 pounds and overall lengths range from 44.4 to 159.8 inches. The breakers are suitable for a wide range of applications thanks to four chisel options – moil, wedge, blunt or conical, according to the company.
Hyundai’s HDB series breakers are engineered to withstand harsh working conditions, says the company. An anti-blank firing (ABF) system, which prevents the breaker from continuing to strike once material has been demolished, comes standard on the HDB50-HDB800 models. This system helps protect the chisel pins, tie bolts and front heads from blank firing and increases the service life of all components. When the auto control valve is turned on, breaker operation will automatically start again by giving a small amount of pressure to the chisel. Automatic stop will take place once the chisel is lifted up or after breaking.
A two-stroke selector system, designed for maximum productivity, comes standard on the HDB50-HDB180 models. This feature allows operators to change from long to short strokes according to their preference and the job at hand.
On the HDB600 and HDB800 models, an energy regeneration valve captures upward flow energy after the piston hits the chisel and retracts back up the cylinder. The technique harnesses up to 15 percent of the energy to be re-applied on the flow energy back down. This feature increases blow speed without the need for additional flow, resulting in higher production rates, according to the company.
These models feature oil seals made by Japan’s NOK Corp., leading to a longer seal life, according to Hyundai. On the HDB210 to HDB800 models, an additional square buffer has been added to increase the durability of the gas seals, step seals and the piston. This buffer seal also helps to minimize the piston’s shaking action.
An optional auto-grease bracket-mounted system is available on the HDB140 to HDB800 models, which the company says allows for automatic greasing several times per day, contributing to longer machine life, particularly for the chisel. HDB series breakers are backed by Hyundai’s dealer network.
