Selecting a hydraulic hammer for a Kobelco excavator requires more than matching the attachment to the excavator's operating weight. Hydraulic flow, operating pressure, carrier stability, attachment weight, working conditions, and the intended application should all be considered before making a purchasing decision.
Kobelco offers excavators across a wide range of operating classes, from compact models such as the SK17SR to larger machines such as the SK210LC, SK350LC, and SK500LC. Each machine requires a hydraulic breaker with suitable impact characteristics and hydraulic requirements.
This guide provides 10 common Kobelco excavator and BEILITE hydraulic hammer combinations as a reference for contractors, equipment dealers, rental companies, fleet owners, and OEM buyers. The recommended combinations should be verified against the specific excavator configuration and auxiliary hydraulic specifications before installation.

How to Select a Hydraulic Hammer for a Kobelco Excavator
1. Check Hydraulic Flow and Operating Pressure
Hydraulic flow and pressure are among the most important factors when matching a breaker to a Kobelco excavator.
Before purchasing a hydraulic hammer, confirm:
Auxiliary hydraulic flow rate
Operating pressure
Maximum allowable pressure
Return-line requirements
Hydraulic hose specifications
Coupler configuration
The breaker should operate within the hydraulic range specified by the manufacturer. Incorrect hydraulic settings can result in reduced impact performance, excessive heat generation, or unnecessary wear on hydraulic components.
2. Match the Breaker to the Application
The required breaker specification depends heavily on the material being processed and the expected working cycle.
For example, concrete demolition may require a different operating configuration from quarry rock breaking. Buyers should consider:
Material hardness
Concrete thickness
Rock size and structure
Required production rate
Daily operating hours
Working environment
Noise restrictions
Required tool type
For urban demolition, noise and vibration control may be important purchasing considerations. For quarrying and mining, tool durability, impact energy, service intervals, and spare-parts availability may have greater importance.
3. Consider Carrier Stability and Attachment Weight
A hydraulic breaker is an extension of the excavator's working equipment. Its operating weight should be compatible with the carrier.
An attachment that is too heavy can affect machine stability, lifting performance, and maneuverability. An attachment that is too light may not provide the required impact characteristics for demanding applications.
Therefore, excavator operating weight should be treated as a starting point rather than the only selection criterion.
4. Evaluate Breaker Construction and Maintenance Requirements
For commercial and fleet applications, attachment durability and maintenance requirements directly affect operating costs.
When comparing hydraulic breaker suppliers, buyers may evaluate:
Cylinder and piston manufacturing quality
Hydraulic sealing system
Tool material and heat treatment
Internal component machining accuracy
Lubrication requirements
Service access
Spare-parts availability
Technical documentation
A breaker designed for straightforward inspection and maintenance can help reduce unnecessary downtime during regular operation.
5. Consider Parts and Technical Support
For contractors and equipment dealers, after-sales support is an important part of the purchasing decision.
Before placing an order, confirm whether the supplier can provide:
Replacement chisels and tools
Seal kits
Hydraulic components
Wear parts
Technical documentation
Installation guidance
Troubleshooting support
Warranty terms
Export and logistics support
For distributors and OEM customers, private-label manufacturing and long-term parts supply may also be relevant requirements.
