For contractors, equipment dealers, rental companies, and fleet owners operating Hyundai excavators, selecting a suitable hydraulic hammer requires more than matching the attachment to the excavator's operating weight.
A hydraulic hammer must also be compatible with the excavator's auxiliary hydraulic flow, operating pressure, mounting dimensions, and working conditions. An incorrect match can affect breaker performance, increase hydraulic system load, and lead to unnecessary maintenance costs.
BEILITE hydraulic hammers are available for excavators across a wide range of operating weights, from compact Hyundai machines to large excavators used in heavy construction, quarrying, and mining applications.
This guide provides a practical reference for selecting and installing a hydraulic hammer for Hyundai excavators.
Hyundai Excavator and Hydraulic Hammer Matching
When selecting a hydraulic hammer for a Hyundai excavator, three specifications should be checked first:
Excavator operating weight
Auxiliary hydraulic flow
Auxiliary hydraulic pressure
The hammer's operating weight should be appropriate for the carrier to maintain stability and allow the excavator to work normally. Hydraulic flow and pressure should fall within the recommended operating range of the breaker.
The following chart provides a reference for matching BEILITE BLTB hydraulic hammers with commonly used Hyundai excavators.

How to Select a Hydraulic Hammer for a Hyundai Excavator
1. Check the Excavator Operating Weight
The first step is to identify the operating weight of the Hyundai excavator.
A breaker that is too heavy may affect machine stability, boom and arm loading, and overall maneuverability. A breaker that is too small may not provide sufficient impact energy for the intended application.
For this reason, the carrier-weight range specified by the hydraulic hammer manufacturer should be used as a starting point rather than selecting a breaker based only on chisel diameter.
2. Confirm Auxiliary Hydraulic Flow
Hydraulic flow determines how much hydraulic oil is supplied to the breaker during operation.
For example, a small Hyundai excavator may operate a breaker within a flow range of approximately 20–40 L/min, while larger breakers may require several hundred liters per minute.
Before purchasing, compare the excavator's available auxiliary flow with the hydraulic hammer's operating flow range.
If the flow is too low, the breaker may not achieve its intended operating frequency or impact performance. Excessive flow can increase oil temperature and place additional load on the hydraulic system.
3. Check Operating Pressure
Hydraulic pressure is another important parameter.
The excavator's auxiliary circuit should provide pressure within the breaker manufacturer's recommended range. The auxiliary relief valve should also be checked before the breaker is put into regular operation.
Pressure that is too high can increase stress on hydraulic components and seals. Pressure that is too low may prevent the breaker from developing its designed impact performance.
4. Consider the Application
The appropriate hydraulic hammer also depends on the material being processed.
Common applications for Hyundai excavators include:
Concrete demolition
Road and bridge renovation
Rock breaking
Quarrying
Trenching
Foundation work
Secondary material reduction
General construction
Concrete demolition and trenching may require a different breaker configuration from continuous quarry or mining work. For demanding applications, buyers should discuss the expected material hardness, operating hours, and duty cycle with the breaker manufacturer before finalizing the model.
Installation of a Hydraulic Hammer on a Hyundai Excavator
Correct installation is important for both breaker performance and excavator protection.
The following procedure provides a general installation reference. The excavator manufacturer's service instructions and the hydraulic hammer manufacturer's installation requirements should always take priority.
Step 1: Install the Mounting Bracket
Park the Hyundai excavator on stable, level ground and lower the attachment to a safe working position.
Align the excavator stick and linkage with the hydraulic hammer's mounting bracket. Install the mounting pins and secure them using the specified retaining hardware.
The bracket dimensions should be confirmed before installation. If a custom bracket is required, the mounting dimensions should be provided to the breaker manufacturer in advance.
Step 2: Connect the Hydraulic Lines
Before connecting the hoses, shut down the excavator and release residual hydraulic pressure according to the manufacturer's procedure.
Connect the hydraulic supply and return lines to the corresponding ports on the breaker.
The hose diameter, connection type, and pressure rating should be appropriate for the selected hydraulic hammer. Keep the hydraulic lines clean during installation to prevent contamination from entering the excavator's hydraulic circuit.
Step 3: Configure the Auxiliary Hydraulic Circuit
The Hyundai excavator's auxiliary hydraulic settings should be adjusted according to the selected breaker.
Where the machine provides a dedicated breaker mode or attachment setting, configure the auxiliary flow and other available parameters according to the manufacturer's recommendations.
Do not assume that the excavator's maximum auxiliary flow is suitable for every hydraulic hammer.
Step 4: Test the Breaker
After installation, inspect the hydraulic connections for leakage.
Start the excavator at low engine speed and operate the breaker intermittently without applying it to the material. This allows the hydraulic circuit to be checked before full-load operation.
After confirming that the hydraulic circuit and mounting system are functioning correctly, gradually increase the engine speed and begin normal operation.
Operating and Maintenance Recommendations
Proper operation has a direct impact on hydraulic hammer service life.
Avoid Blank Firing
Do not operate the breaker when the chisel is not firmly positioned against the material.
Repeated blank firing can transmit unnecessary shock loads through the breaker and excavator attachment system. Use the breaker only when the tool is properly positioned against the working surface.
Do Not Use the Chisel for Prying
A hydraulic breaker is designed primarily for impact work. Using the chisel as a lever to pry or move large rocks can place excessive side loads on the tool and bushings.
If material needs to be repositioned, use the appropriate excavator attachment or operating method.
Maintain Regular Greasing
The chisel and front bushing require regular lubrication during operation.
For continuous breaking work, grease should be applied according to the hydraulic hammer manufacturer's maintenance schedule. High-temperature grease suitable for hydraulic breaker applications should be used.
The exact lubrication interval may vary depending on the model, working conditions, and operating intensity.
Monitor Hydraulic Oil Temperature
Hydraulic oil temperature should be monitored during extended breaker operation.
If oil temperature rises beyond the excavator manufacturer's recommended operating range, stop the breaker and investigate the hydraulic flow, pressure, return-line restriction, oil condition, and cooling system.
Inspect Wear Components
Regularly inspect the chisel, front and rear bushings, retaining components, hydraulic hoses, and mounting bracket.
For contractors and rental fleets, establishing a routine inspection schedule can help identify wear before it develops into a larger repair issue.
What Should Buyers Confirm Before Ordering?
For fleet owners, dealers, and procurement teams purchasing hydraulic hammers for Hyundai excavators, providing complete machine information can make the selection process faster and more accurate.
Before requesting a quotation, prepare the following information:
Hyundai excavator model
Excavator operating weight
Available auxiliary hydraulic flow
Auxiliary hydraulic pressure
Hydraulic hose and connection specifications
Mounting dimensions
Main application
Material hardness or working conditions
Expected operating hours
Required breaker quantity
For fleet purchases, buyers should also consider spare parts availability, warranty support, maintenance requirements, delivery lead time, and after-sales technical support.
