Product Description
Premium SB45 excavator breaker attachment, 75mm Soosan SB45 hydraulic breaker hammer for 8-12 ton excavators. Heavy-duty side type hydraulic breaker attachment with nitrogen accumulator, easy maintenance, high efficiency, perfect for municipal construction and road repair.
- Compact & Lightweight – Perfect for 8–12 ton excavators, flexible in narrow spaces
- Triangular Reinforced Frame – Thickened steel plates, strong lateral impact resistance
- Easy Maintenance Access – Open side design, fast seal & wearing part replacement
- Hydraulic-Gas Combined Power – Nitrogen accumulator boosts impact efficiency by 30%
- Built-In Damping System – Reduces reverse vibration, protects excavator boom
- Universal Mounting Interface – Fits CAT, Komatsu, SANY, XCMG, Doosan and more
- 100% Factory Load Tested – Full-cycle pressure & impact test before shipment
The side type hydraulic breaker attachment operates on a hydraulic-pneumatic cycle:
- Charging Stroke: Hydraulic oil enters the lower cylinder chamber, pushing the piston upward and compressing nitrogen in the top accumulator to store energy.
- Impact Stroke: When the piston reaches the top, the hydraulic valve reverses. High-pressure oil and expanding nitrogen drive the piston downward at high speed to strike the chisel.
- Energy Transfer: Impact force travels through the chisel to break concrete, asphalt or rock.
- Cycle Repeat: The piston returns to the starting position, repeating 400–800 times per minute for continuous breaking.
The open triangular frame dissipates heat quickly, supporting long continuous operation without performance degradation.
| Advantage | Our SB45 Attachment | Ordinary Breaker |
|---|---|---|
| Power System | Hydraulic-gas combined, 30% higher efficiency | Pure hydraulic, weak impact |
| Frame Strength | Thickened triangular steel plate, reinforced | Thin flat plate, easy to deform |
| Impact Stability | Stable force, consistent frequency | Fluctuating force, easy to stall |
| Heat Dissipation | Excellent open structure | Poor, easy to overheat |
| Service Life | 6000+ working hours | 2000–3000 working hours |
| Maintenance | Side open, 30% faster maintenance | Difficult disassembly |
| Cost Performance | 65% of OEM price | Low price but short service life |
