Choosing the hydraulic breaker for your excavator requires careful consideration of its configuration. This decision directly impacts efficiency, safety, and the lifespan of both the breaker and the carrier equipment. We guide you through the essential parameters to ensure optimal performance for your projects.
Understanding Hydraulic Breaker Configuration: A Quick Guide
Selecting the correct hydraulic breaker involves matching its technical specifications with your excavator’s capabilities and the demands of the job. This alignment is crucial for achieving peak productivity and preventing premature wear. An improperly matched breaker can lead to reduced breaking power, increased fuel consumption, and potential damage to the excavator’s hydraulic system. We focus on key configurations like carrier operating weight, oil flow, operating pressure, and chisel diameter to help you make an informed decision.
Matching Your Hydraulic Breaker to Excavator Specifications
Carrier Operating Weight: The Foundation of Compatibility
The carrier operating weight is the primary factor in determining compatibility. The excavator must be heavy enough to safely and stably handle the hydraulic breaker’s weight and absorb its impact forces. If the breaker is too heavy for the excavator, it can cause instability, excessive wear on the excavator’s boom and pins, and even structural damage. Conversely, a breaker that is too light will not deliver sufficient breaking power for heavy-duty tasks. We always recommend checking the manufacturer’s guidelines for both the excavator and the breaker to ensure a safe and effective match.
Oil Flow (l/min): Fueling Your Breaker’s Power
Oil flow refers to the volume of hydraulic fluid supplied by the excavator to the breaker per minute. This parameter directly influences the breaker’s impact rate (BPM). A higher oil flow generally results in a higher impact rate, meaning more blows per minute and faster material breakdown. It is critical that the excavator’s hydraulic pump can provide the oil flow specified by the hydraulic breaker manufacturer. Insufficient oil flow will reduce the breaker’s performance, while excessive flow can cause overheating and damage to the breaker’s internal components. For instance, a BLT-155 breaker requires an oil flow of 180~240 l/min to operate at its specified impact rate of 200~300bpm.
Operating Pressure (bar): The Force Behind the Impact
Operating pressure is the hydraulic pressure at which the breaker functions. This pressure determines the force of each impact. Matching the breaker’s required operating pressure with the excavator’s hydraulic system output is essential. Too little pressure results in weak impacts, making the breaker ineffective. Too much pressure can overstress the breaker’s internal components, leading to seal failures and structural fatigue. Our breakers are designed to operate within specific pressure ranges to deliver consistent and powerful impacts. For example, the BLT-155 operates at 200~220bar, delivering substantial breaking force.
Chisel Diameter: Tailoring to the Task
The chisel diameter indicates the size and robustness of the working tool. A larger chisel diameter generally corresponds to a more powerful breaker designed for heavier materials and larger breaking tasks. Smaller chisel diameters are suitable for precision work or breaking softer materials. The choice of chisel type (e.g., moil point, narrow chisel, blunt tool) also depends on the specific application, such as breaking hard rock, concrete demolition, or asphalt cutting. We offer various chisel options to maximize the breaker’s versatility across different job sites.

The BLT-40, with a chisel diameter of 40mm and a total weight of 86kg, is suitable for 0.5–1.2t excavators. It operates with an oil flow of 15~30 l/min and an operating pressure of 90~120bar. The BLT-70, designed for 4.5–6t excavators, features a 70mm chisel diameter, a total weight of 362kg, and requires an oil flow of 40~70 l/min at an operating pressure of 110~140bar. These models are ideal for urban demolition, landscaping, and small-scale trenching.
Mid-Range Power: The BLT-135 and BLT-155
When projects demand more power and larger excavators, the BLT-135 and BLT-155 models deliver. The BLT-135, with a 135mm chisel diameter, weighs 1736kg and is designed for 18~22t excavators. It requires an oil flow of 100~150 l/min and operates at 160~180bar. The BLT-155, one of our most powerful mid-range options, features a 155mm chisel diameter, weighs 2610kg, and is compatible with 27~33t excavators. It operates with an oil flow of 180~240 l/min and an operating pressure of 200~220bar. These breakers are well-suited for quarrying, large-scale construction, and breaking heavily reinforced concrete.

From Our Field Engineers: Avoiding Common Mismatches
Our field engineers often see issues arising from mismatched equipment. A common mistake is using a breaker that is too large for the excavator’s hydraulic capacity. This can lead to the excavator’s hydraulic system overheating, reducing its lifespan. Another frequent problem is neglecting the accumulator gas pressure. If the accumulator is not correctly charged, the breaker’s impact force significantly diminishes, leading to slow progress and increased wear on the piston. Always ensure your accumulator is charged to the manufacturer’s recommended pressure, typically 55~60bar for our larger models like the BLT-155. Regular checks and maintenance of these parameters are essential for sustained performance.

Frequently Asked Questions About Hydraulic Breaker Selection
What happens if my hydraulic breaker is too heavy for my excavator?
If your hydraulic breaker is too heavy, the excavator may become unstable, leading to safety hazards. It can also cause excessive stress on the excavator’s boom, pins, and hydraulic system, resulting in premature wear and potential structural damage. Always match the breaker’s weight to the excavator’s recommended carrier operating weight range.
How does oil flow affect hydraulic breaker performance?
Oil flow directly influences the breaker’s impact rate. Higher oil flow generally means more impacts per minute, leading to faster material breakdown. If the excavator’s oil flow is insufficient, the breaker will operate below its optimal impact rate, reducing its efficiency.
Why is operating pressure important for a hydraulic breaker?
Operating pressure determines the force of each impact. Correct operating pressure ensures the breaker delivers its full breaking power. Too low pressure results in weak impacts, while too high pressure can damage the breaker’s internal components, such as seals and the piston.
Can I use any chisel with my hydraulic breaker?
While many chisels are interchangeable by diameter, the specific type of chisel (e.g., moil point, narrow chisel, blunt tool) should be selected based on the material you are breaking and the specific application. Using the wrong chisel type can reduce efficiency and increase wear on both the chisel and the breaker.
How often should I check the accumulator gas pressure?
The accumulator gas pressure should be checked regularly as part of routine maintenance, typically every 100-200 operating hours, or as recommended in your breaker’s manual. Correct gas pressure is crucial for maintaining optimal impact force and protecting the hydraulic system.
