Kinton Parts is trusted by professionals worldwide for delivering high-quality parts for excavators, bulldozers, and other construction machinery—with guaranteed performance and durability.
The silent-type hydraulic breaker, also known as a box-type breaker, features a fully enclosed outer shell with noise-dampening materials to reduce sound and vibration during operation. Unlike side-type or top-type breakers, silent breakers are particularly suited for environments with noise regulations, such as city roads, urban buildings, tunnels, and indoor demolition.
Main Features and Advantages
- Low Noise Housing: Outer box casing reduces noise by up to 50% compared to side-type models.
- Anti-Vibration Structure: Rubber dampeners absorb shock, minimizing stress on excavator arms.
- Heavy-Duty Impact Piston: High-hardness materials (usually 42CrMo) provide long service life under tough conditions.
- Simple Maintenance: Centralized greasing and accessible bolt design ensure ease of service.
- Environmentally Friendly: Helps meet noise regulations on sensitive job sites
Breaker Types Overview
To help you select the right tool for your needs, here's a brief comparison of hydraulic breaker types:
| Type | Structure | Noise Level | Application Areas |
|---|---|---|---|
| Side Type | Exposed frame, compact | Higher | Open-area demolition, mines |
| Top Type | Mounted directly on boom | Moderate | Bridge decks, construction sites |
| Silent Type | Fully enclosed box housing | Low | Urban areas, residential construction |
Silent-type breakers combine powerful performance with excellent noise control, making them the top choice for city and indoor works.
Internal Valve vs. External Valve Hydraulic Breakers
We offer both internal valve and external valve hydraulic breaker models, each designed to meet different working needs and maintenance preferences. The visual diagram above highlights the structural and functional differences between these two systems.
External Valve System
- The control valve is mounted externally on the breaker body, making it easier to access for maintenance and repair.
- This setup provides strong impact energy and flexible control but includes more external piping, increasing the risk of leakage or damage in high-vibration environments.
- A dedicated energy recovery valve and advanced accumulator help improve strike efficiency and hydraulic stability during heavy-duty cycles.
Internal Valve System
- The valve is integrated directly inside the cylinder, simplifying the oil circuit and reducing parts exposure.
- This structure minimizes hydraulic resistance, enhances response speed, and delivers more consistent striking power.
- A simplified air chamber design improves buffer control while reducing component stress and oil contamination.
Key Differences
- Maintenance: External valve models are easier to service; internal valves reduce daily maintenance needs.
- Durability: Internal systems are more compact and dust-resistant, better for harsh working environments.
- Performance: Internal valves offer faster oil flow and energy efficiency, while external valves provide robust control and customization.
Whether you need quick maintenance access or enhanced impact performance, our breakers with both valve systems are designed to meet your job site requirements.
Available Chisel (Rod) Types
We offer a variety of chisel rods to match different working conditions:
| Chisel Type | Application |
|---|---|
| Moil Point | General demolition, concrete breaking |
| Flat Type | Asphalt, slab, and flat-surface demolition |
| Conical Type | Rock trenching and precise breaking |
| Blunt Type | Boulder splitting and high-impact tasks |
| Wedge Type | Quarrying, splitting rock from fissures |
All chisels are manufactured with premium heat-treated alloy steel for superior wear resistance and durability.
Compatibility & Mounting Range
Our silent-type breakers are compatible with most excavators from 6 to 30 tons, including but not limited to:
- Komatsu: PC60, PC120, PC200
- Caterpillar: 306, 312, 320D
- Doosan: DX60, DX140, DX225
- Volvo: EC55, EC140, EC210
- Hyundai: R60, R140, R210
If you have a specific machine model, we can help confirm bracket size and match the correct chisel length and diameter.
Quality & Testing
Each unit undergoes:
- Hardness testing of the chisel and piston
- Pressure testing for hydraulic cylinder leakage
- Noise & vibration testing in operational simulations
- Welding & enclosure inspection for durability and sealing
We guarantee consistent performance and long service life under varied job site conditions.
