DNHI Co., Ltd. (CEO Gap-seon Jin) acquired Daenong Heavy Industries' "DNB Brand" with Daenong Heavy Industries' breaker division in 2008 and became a production company specializing in hydraulic breakers. After the acquisition, it has been improving its technology through its own R&D, and in 2014, it is recognized by the industry as it succeeded in developing and commercializing the world's first D500ls model that can be mounted on the world's largest 140-ton excavator.

DNB Breaker is a highly recognized Hydraulic Breaker manufacturer in overseas markets, has more than 35 years of experience and is a low-vibration, low-noise, full-pressure premium product sold mainly in Europe and Australia. It is intended to strike the target to dismantle buildings, demolition, and crushing paved roads. It is used by attaching it to an excavator, and it is a principle that the piston in the hydraulic breaker is moved up and down from the hydraulic power source supplied from the excavator's hydraulic motor, hits the chisel (tool), and transmits the hitting energy to the crushed object.

The product is Europe's preferred Full Hydraulic Type, and the noise is 20-30% lower than the gas type and the body is sealed in a box form, preventing internal penetration of foreign substances such as dust during work, so the cycle of regular maintenance is 1.5 times longer than that of the gas type.

The Fully Hydraulic Type operates with oil, and the Gas Type operates with oil 50% and nitrogen 50%. Hydraulic type has no hits than Gas type and has 20-30% higher batting energy, which can increase work efficiency.

Because the Hydraulic type uses only the flow/hydraulic pressure of the excavator, the stability of the excavator and the fatigue of the worker are low, while the gas type has strong repulsive force that bounces during work, so the impact is transmitted to the excavator and the worker's fatigue is high. In addition, the Hydraulic type can be recognized by the operator before a serious problem occurs due to automatically stopping work with the bolt broken, but the Gas type can work regardless of the bolt breaking, which may cause secondary problems, making it difficult for the operator to recognize the problem.

An official from DNHI said, "Compared to advanced countries' hydraulic type breaker producers, DNHI is evaluated as having 20-30% superior price competitiveness and never lagging behind in quality and performance," adding, "DNA has a year and a half product guarantee period and does not lose competitiveness compared to global brand companies."

In addition, he explained, "It is also a relative strength that Daenong Heavy Industries has exported to developed markets since the 1990s, so there are already many used products, old products, and parts in developed markets, so it can be recycled."

Regarding future plans, he said, "We want to become a company that contributes to the international infrastructure industry by supplying products with global quality and performance."

Meanwhile, Chungbuk Techno Park has prepared and focused on Chungbuk National Innovation Cluster TF since last year to strengthen the competitiveness of regional representative industries. The main content is to establish a national innovation cluster in Chungcheongbuk-do, enhance global competitiveness and lay new growth bases for local industries by "intelligent high-tech parts industry"
