SQ Series | Professional Hydraulic Breaker Chisel Manufacturer

Silent Operation & Intelligent Control: SQ Series’ Standout Advantages

The Soosan SQ Series hydraulic breakers are professional equipment for medium and heavy-duty construction. Leveraging the brand’s mature hydraulic technology, they balance operational efficiency, stability and maintenance ease, suitable for mining, building demolition and road construction.

Featuring an optimized hydraulic valve core, the series has an impact frequency of 350-600 times/min, adaptable to working media: 500-600 times/min for hard rock crushing and 350-450 times/min for loose soil excavation to save energy. Compatible with 6-30 ton excavators, it enables accurate installation via standard flange connection without additional modification.

Its high-strength alloy steel drill rod (135mm-185mm diameter) undergoes high-frequency quenching (HRC55+), offering 800-1200 hours of service life. The integrated cast shell with internal buffers reduces vibration damage and noise (8-10dB lower than traditional odels), ideal for urban construction.

Equipped with a built-in intelligent pressure regulating module, the SQ series monitors pressure and load in real time, cutting fuel consumption by 5-8% while ensuring efficiency. The 10μm precision hydraulic oil filtration system protects key components and extends hydraulic system life.

With modular design, vulnerable parts (drill rods, bushings, oil seals) can be replaced in 30 minutes via side ports. It has clear lubrication ports (25-hour cycle), and daily inspection only requires checking oil level, temperature and seal leakage. The IP65 dustproof and waterproof structure plus wear-resistant base plate adapts to harsh environments, with annual maintenance costs at 3-5% of the total price.
