Silent Series Technology
Why SQ Series Stands Out
The SQ Series combines SOOSAN's 40-year hydraulic expertise with advanced noise and vibration reduction technology — purpose-built for urban and noise-sensitive environments.
Silent Technology
Patented sound-dampening housing reduces noise by up to 10 dB vs. standard breakers — ideal for urban and noise-restricted job sites.
High Efficiency
Optimized hydraulic circuit delivers consistent blow energy with lower oil consumption, reducing operating costs per hour.
Vibration Damping
Integrated anti-vibration mounts protect the excavator arm and reduce operator fatigue during extended breaking operations.
Auto Lubrication
Built-in auto-grease system ensures continuous chisel lubrication, extending tool life and reducing maintenance downtime.
Urban-Ready Design
Compact, enclosed body design minimizes dust and debris scatter — compliant with urban construction site regulations worldwide.
CE & ISO 9001
Fully certified to international standards. Trusted by contractors in Europe, the Middle East, Southeast Asia, and beyond.
Construction Machinery Applications
Where SOOSAN Heavy
Breakers Work
The SQ Series is the go-to choice for contractors operating in noise-restricted zones. From urban demolition to underground metro construction, SQ breakers deliver full power with minimal acoustic impact.
🏙
Urban Demolition
Building teardown, reinforced concrete breaking, and structural dismantling in city centers where noise limits apply 24/7.
🏢
Indoor Breaking
Floor slab removal, basement excavation, and interior demolition where enclosed spaces demand low-noise equipment.
🌙
Night Operations
Road maintenance, utility repairs, and emergency excavation during nighttime hours in residential and commercial zones.
🏘
Residential Areas
Foundation work, drainage installation, and site preparation adjacent to homes, schools, and hospitals.
🔧
Trenching & Utilities
Pipeline and cable installation in urban streets with strict noise ordinances and vibration-sensitive underground infrastructure.
🚇
Tunnel & Metro Work
Underground construction, metro line expansion, and tunnel face breaking where noise and vibration control is critical.

Selection Guide
How to Choose the Right SQ Model
01
01
Match Your Excavator
Select the SQ model that matches your excavator operating weight. SQ10 for 0.8–1.5t mini excavators up to SQ150 for 25–35t large machines.
02
02
Assess Noise Requirements
For standard outdoor sites, the SB Series may suffice. For urban, indoor, or night work, the SQ Series silent design is the right choice.
