Kinton Parts is trusted by professionals worldwide for delivering high-quality parts for excavators, bulldozers, and other construction machinery—with guaranteed performance and durability.
Top Type Hydraulic Breakers are mounted on the top of the excavator’s boom, with the breaker body aligned vertically. This design delivers a more direct impact force along the centerline, making it highly effective for vertical rock breaking, foundation removal, and road surface demolition.
Compared to side and silent types, the Top Type offers:
- Stronger straight-line impact transmission
- Simpler structure for easier maintenance
- Better cooling and heat dissipation performance
Key Components & Material
Our top type breakers are engineered with precision-forged and heat-treated components, ensuring consistent high performance under tough conditions:
- Piston & Cylinder: Made of high-strength alloy steel (20CrNiMo), precisely honed for smooth operation and long wear life.
- Front & Back Head: Forged steel bodies with advanced tempering treatment.
- Chisel Rod: Options include Mo40, 42CrMo, or customized materials based on impact needs.
- Valve System: Optional internal or external valve structure based on performance demands.
- Nitrogen Chamber: Energy-absorbing chamber helps regulate recoil and ensures consistent force.
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.
Compatible Excavator Models
This Top Type breaker can be matched with a wide range of excavators between 6 to 30 tons. Compatible brands include:
- Caterpillar, Komatsu, Doosan, Hyundai, Volvo, Hitachi, SANY, and more.

Maintenance Tips
- Regularly check nitrogen gas pressure and refill as needed.
- Use only clean hydraulic oil (recommendation: ISO VG46 or OEM spec).
- Avoid blank firing to reduce piston wear.
- Replace bushings and seals periodically depending on usage conditions.
