Hyundai Construction Equipment Americas Inc., has introduced its first attachment product line to the North American market: a full line of hydraulic breakers. Consisting of 14 different models HDB10 through HDB800, the all new HDB series breakers complement Hyundai’s excavators of all sizes.

Hyundai’s HDB series breakers offer a powerful impact with a large chisel diameter from 1.6 to 7.9 in. (4 to 20 cm). Operating weights range from 271 to 12,401 lb. (123 to 5,625 kg) and overall lengths range from 44.4 to 159.8 in. (113 to 406 cm). The breakers are suitable for a wide range of applications due to four chisel options — moil, wedge, blunt or conical.

Hyundai’s HDB series breakers are engineered with advanced technology for optimum performance despite harsh working conditions. 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.

For maximum productivity, a two stroke selector system 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 is provided to increase efficiency. This system captures upward flow energy after the piston hits the chisel and retracts back up the cylinder and harnesses up to 15 percent to be applied on the flow energy back down. This feature increases blow speed without the need for additional flow, resulting in higher production rates.

Not only are the HDB series breakers advanced, productive and efficient, they’re also highly durable. These models feature only NOK oil seals leading to a longer seal life. On the HDB210 to HDB800 models, an additional square buffer was 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, according to the manufacturer.

An optional auto grease bracket mounted system is available on the HDB140 to HDB800 models, which allows for automatic greasing several times a day contributing to longer machine life, particularly for the chisel.

Like all Hyundai products, the HDB series breakers are backed by Hyundai’s extensive dealer network.
