SOOSAN Hydraulic Breakers: High Durability for Demolition & Road Construction

Forty Years of Percussion Engineering

Since the first breaker rolled out from the Soosan factory back in 1984, the ingenious and patented design of Soosan breakers have received recognitions for its superb performance from worldwide customers. That four-decade track record is not accidental — it reflects a deliberate engineering philosophy built around a patented unique valve system that simplifies the hydraulic circuit, needs less oil flow, makes high efficiency and allows reliable operation. Fewer moving parts mean fewer things that can go wrong on a demolition site or in the middle of a road-maintenance window.

The SB series sits at the core of the Soosan line, running from the compact SB10 for 6–9 tonne excavators all the way up to the SB157 and SB160 for the heaviest carriers. Soosan designs and builds hydraulic breakers, compactors, crawler drills and other attachments to perform exactly and reliably as you would expect — with power, reliability and an entire support team to stand behind them, and you. Soosan's commitment to quality and service is a commitment to you and your operational efficiency. The company holds ISO 9001 and ISO 14001 accreditation and treats both certifications as the core of its corporate mission rather than a compliance checkbox.

What Demolition and Road Work Actually Demand

Road construction and building demolition sit at opposite ends of the impact-energy spectrum but share one requirement: the breaker cannot stop working mid-shift. On a road job, the excavator typically moves continuously along a pavement strip — cement pavement breaking, foundation excavation, and highway repair all need a tool that cycles reliably for hours without thermal buildup or valve wear. On a demolition site, the challenge shifts toward structural unpredictability: one swing hits weathered brick, the next hits post-tensioned concrete, and the breaker has to handle both without overloading the carrier's hydraulic system.

Two engineering decisions in the TS-P and TR-F lines address both scenarios directly. First, TS-P series brackets fully isolate the power-cell with premium quality urethane cushions and wear plates which absorb shock and vibration resulting in reduced noise emission and failures. That isolation extends the life of the excavator boom as much as the breaker itself — a point that matters more on road work, where the same machine runs all day, than on a demolition project where the carrier takes natural breaks between structural elements. Second, the fully enclosed housing, dust protector and slim profile with robust structure deliver better visibility, reduced dirt entry and high durability — directly relevant on road jobs where disturbed base material and flying aggregate are constant hazards to internal seals.

Durability That Shows Up in the Field

Soosan hydraulic breakers conform to all the small, medium and large excavators on the market, and the strike force and durability are leading the industry level. That broad compatibility matters for fleets running mixed excavator brands — the same SB81, for example, can be adapted to CAT, Doosan, Hyundai, Komatsu, and Volvo carriers without fabricating a custom adapter for each machine.

Material choices back up the performance claims. We use only the highest quality steel and employ professional heat treatment technology, ensuring that each hydraulic breaker is crafted with precision and care. Heat-treated pistons and nitrided chisel surfaces resist the surface fatigue that is the primary failure mode in road breaking, where the tool repeatedly strikes hard aggregate just below the asphalt rather than penetrating deep into a rock mass. The HARDOX reinforced housing option — available on heavier SB models — adds another layer of abrasion resistance for demolition work in environments where the outer shell takes as much punishment as the chisel.

Soosan breakers are more powerful and lighter than other same class breakers, which pays a practical dividend on road projects: a lighter attachment means less cycle fatigue on the excavator arm during a full-day paving-removal run, and it leaves more payload margin for counterweight when the operator needs reach rather than brute force. Simple structure of TS-P series enables the customers to reduce maintenance cost — and on a road project with a tight traffic-management window, every hour saved on a seal replacement or chisel change is an hour the lane stays open and the penalty clock stays stopped.
