Hyundai Construction Equipment Americas Inc. introduced its first attachment product line to the North American market: a full line of hydraulic breakers. Consisting of 13 different models HDB10 through HDB450, the 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 6.5 inches. Operating weights range from 271 to 8,186 lb and overall lengths range from 44.4 to 141.5 inches. The breakers are suitable for a range of applications thanks 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-HDB450 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.
The models feature only NOK oil seals leading to a longer seal life. On the HDB210 to HDB450 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.
An optional Auto Grease Bracket Mounted system is available on the HDB140 to HDB450 models, which allows for automatic greasing several times a day contributing to longer machine life, particularly for the chisel.
The HDB series breakers are backed by Hyundai’s dealer network.
