Soosan Hydraulic Breakers
Soosan Heavy Industries
Volume manufacturer with facilities in South Korea and China — broad SB-series range
Overview
Soosan Heavy Industries is one of the largest hydraulic breaker manufacturers in the world and among the highest-volume producers globally. The company operates manufacturing facilities in both South Korea and China. The SB series covers excavators from 1 to 50+ tons and is widely distributed across Asia, the Middle East, and emerging markets. Soosan breakers are known for competitive pricing and broad availability.
History
Soosan was founded in 1981 in Incheon, South Korea, initially as a manufacturer of construction attachments. The company expanded into hydraulic breakers in the 1980s as demand from South Korea's rapidly growing construction sector increased.
Through the 1990s and 2000s, Soosan built an extensive distribution network across Asia and the Middle East, establishing itself as a volume manufacturer serving price-sensitive markets. The company invested in manufacturing automation and quality control systems to support high-volume production while maintaining competitive pricing.
Today, Soosan operates manufacturing facilities in both South Korea and China, exporting to over 80 countries. The SB series remains the company's core product line, with models ranging from the compact SB10 for mini excavators to the SB series for large mining machines.
Key Technologies
Gas-Hydraulic Percussion System
Soosan breakers use a conventional gas-hydraulic percussion system where nitrogen gas in the accumulator works in conjunction with hydraulic oil to drive the piston. This is the industry-standard approach used by most major manufacturers. The system provides reliable performance and straightforward maintenance.
Auto-Stroke Control
Larger Soosan models (SB50 and above) incorporate an auto-stroke control system that automatically adjusts the piston stroke length based on material hardness. In hard rock, the system uses a longer stroke for maximum impact energy. In softer materials, it switches to a shorter, faster stroke for higher frequency. This improves productivity across varying material conditions.
Dust Prevention System
Soosan breakers include a dust prevention system that uses compressed air or nitrogen to create positive pressure in the front head, preventing dust and debris from entering the bushing area. This extends front head bushing life in dusty operating environments.

Strengths & Limitations
Strengths
- Broad product range covering all excavator classes from 1 to 50+ tons
- Competitive pricing — typically 20–40% below European brands at equivalent specifications
- Wide global distribution network with parts availability in most markets
- Straightforward design facilitates field maintenance and repair
- Established track record in Asian and Middle Eastern construction markets
Limitations
- Impact energy and frequency specifications are generally below European premium brands at equivalent weight class
- Seal and bushing life may be shorter than premium brands in demanding applications
- Less advanced technology features compared to Epiroc, Furukawa, or Rammer
- After-sales support quality varies significantly by distributor
Market Position
Soosan occupies the value segment of the hydraulic breaker market. The brand competes primarily on price and availability rather than technology leadership. It is the dominant choice in price-sensitive markets (Southeast Asia, Middle East, Africa) and is widely used by contractors who prioritize low acquisition cost and parts availability over maximum performance.
In premium markets (Western Europe, North America, Australia), Soosan competes as a budget alternative to European brands, typically chosen for lower-intensity applications where maximum performance is not critical.
