Kinton Parts is trusted by professionals worldwide for delivering high-quality parts for excavators, bulldozers, and other construction machinery—with guaranteed performance and durability.
A Side Type Hydraulic Breaker (also called a Triangle Type Breaker) is a demolition attachment mounted on the side of the bracket rather than on top. This structure lowers the breaker’s center of gravity, improving stability and making it ideal for powerful vertical strikes against concrete, rock, or asphalt. It is especially favored in road construction, mining, and urban demolition environments where compactness and strength matter.
Key Features & Advantages
- Triangle Side-Mount Design
The body is fixed between two side plates, creating a sturdy frame that effectively absorbs vibrations and protects the cylinder. - Simplified Maintenance
Fewer components and easy disassembly allow for faster maintenance and lower operating costs. - High-Impact Energy Output
Optimized piston-cylinder design delivers strong and consistent blows for demanding demolition tasks. - Wider Compatibility
Available in various sizes and mounting brackets to suit excavators from 1 ton to 40 tons. - High-Quality Chisel Options
Compatible with pointed, blunt, flat, and wedge-type chisels based on application needs.
Material & Manufacturing Highlights
- Cylinder: Made of forged alloy steel and treated with deep heat-hardening to ensure durability under continuous impact.
- Piston: Precision-machined for tight fit and efficient energy transfer, with chrome plating to reduce wear.
- Tool Bushes: Easily replaceable bushing system for tool alignment and impact protection.
- Valve System: Integrated or external valve designs are both available depending on customer requirements (see diagram).
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.
Compatible Chisel Types
Choose the ideal tool shape for your operation:
| 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.
Excavator Compatibility & OEM Options
Our side type breakers can be customized to fit all major excavator brands:
- Komatsu, Hitachi, Hyundai, Doosan, CAT, Volvo, Sany, XCMG, Kobelco, and others.
OEM bracket and hose connection customization is available upon request.
Maintenance Tips
- Regularly check hydraulic oil levels and filter condition.
- Replace tool bushings before excessive wear damages the piston.
- Use correct nitrogen pressure for optimal impact performance.
- Always match breaker size and oil flow to the excavator’s specifications.
