How to Choose a Hydraulic Breaker: A Guide for Optimal Performance

Written by: xuansc2144@gmail.com Published:2025-11-7

Selecting the correct hydraulic breaker is crucial for maximizing productivity, ensuring safety, and protecting your investment. A mismatch between your carrier and the breaker can lead to reduced efficiency, increased wear on both machines, and potential safety hazards. We guide you through the essential factors to consider, drawing on our extensive experience in the field.

Selecting the Right Hydraulic Breaker

Choosing the right hydraulic breaker involves more than just picking a size. It requires a detailed understanding of your carrier’s capabilities, the specific application, and the breaker’s technical specifications. Our goal is to help you make an informed decision that leads to optimal performance and longevity for your equipment. We ensure our guidance is practical and directly applicable to your operational needs.

Matching Your Breaker to Your Excavator

Understanding Carrier Weight Class

The first step in choosing a hydraulic breaker is to ensure it is compatible with your excavator. The ‘Suit Excavator (t)’ or ‘Carrier Weight Class (t)’ specification indicates the recommended weight range of the host machine. An undersized breaker will lack breaking power, while an oversized one can damage the excavator’s boom and hydraulic system. For example, our BLT-40 model is designed for 0.5–1.2t excavators, while the BLT-155 is for 27–33t machines. This precise matching prevents undue stress on your equipment.

Hydraulic Flow and Pressure Requirements

Your excavator’s hydraulic system must meet the breaker’s requirements for ‘Oil Flow (l/min)’ and ‘Operating Pressure’. If the oil flow is too low, the breaker will operate slowly and with reduced impact force. If the pressure is too high, it can damage the breaker’s internal components. Our breakers are designed to operate within specific ranges to ensure peak performance and prevent damage. For instance, the BLT-100 requires an oil flow of 80~110 l/min and an operating pressure of 150~170bar. Always verify these parameters against your excavator’s specifications.

Key Specifications of Hydraulic Breakers

Breaker Operating Weight

The ‘Breaker Operating Weight’ is the total weight of the hydraulic breaker, including the working tool and mounting bracket. This weight influences the stability of the excavator and the effective transfer of impact energy. A heavier breaker generally indicates more robust construction and greater breaking power, but it must remain within the excavator’s lifting capacity and stability limits. Our BLT-135, for example, weighs 1736kg, making it suitable for larger excavators in demanding applications.

Hydraulic Breaker

Working Tool Diameter and Type

The ‘Working Tool Diameter’ and type are critical for effective breaking. A larger diameter tool typically means a more powerful breaker, suitable for harder materials. The type of working tool—such as a MOIL POINT for general breaking, a NARROW CHISEL for trenching, or a BLUNT TOOL for secondary breaking—should be selected based on the specific task. Using the correct tool minimizes wear and maximizes breaking efficiency. We offer a range of working tools to suit various applications, ensuring you always have the right tool for the job. For specific applications, consider our Forging Tool options for enhanced durability.

Impact Rate and Energy

The ‘Impact Rate (BPM)’ refers to how many times the piston strikes the working tool per minute. A higher impact rate can be beneficial for softer materials or for quickly breaking down already fractured rock. However, for harder materials, a lower impact rate with higher impact energy per blow is often more effective. We design our breakers to offer an optimal balance, such as the BLT-70 with an impact rate of 500~900bpm, allowing for versatility across different material types. The Piston inside the Cylinder Body Assembly is responsible for generating this impact.

Accumulator Gas Pressure

The ‘Accumulator’ plays a vital role in a hydraulic breaker’s performance and longevity. It stores hydraulic energy and absorbs pressure spikes, protecting both the breaker and the excavator’s hydraulic system. Maintaining the correct ‘Accumulator Gas Pressure’ is essential. Too low, and the breaker loses power and experiences increased vibration; too high, and it can damage the accumulator itself. Our models like the BLT-70 maintain an Accumulator Nitrogen Pressure of 55~60bar, ensuring consistent performance and system protection. Regular checks of the Accumulator Assembly are part of our recommended maintenance.

Considering Your Application

Demolition and Construction

For demolition and general construction tasks, you need a breaker that can handle a variety of materials, from concrete to asphalt. Factors like noise levels might also be important in urban areas, making a Silent Outer Casing a preferred choice. We provide breakers that offer a balance of power and control for these diverse environments.

Quarrying and Mining

Quarrying and mining operations demand breakers with high impact energy and durability to break hard rock. Here, the ‘Working Tool Diameter’ and the overall robustness of the Breaker Box are paramount. Our larger models, such as the BLT-155 and BLT-165, are engineered for the most demanding rock-breaking applications, providing sustained power in harsh conditions.

Specialized Tasks

Some tasks require specialized tools. For instance, an ASPHALT CUTTER is specifically designed for cutting asphalt or frozen ground, offering a clean and efficient cut. Understanding these specialized needs helps us recommend the most appropriate tool and breaker combination for your project. The Tool Pin and Outer Bushing are critical components that ensure the working tool performs effectively.

From Our Field Engineers: Maximizing Breaker Lifespan

Proper maintenance is key to extending the life of your hydraulic breaker. We always emphasize daily lubrication of the working tool using Chisel Paste through the Grease Nipple. This prevents premature wear on the Inner Bushing and Outer Bushing. Furthermore, regularly checking the Seal Kit and replacing worn seals, especially the Dust Seal and O-ring, prevents contamination and maintains hydraulic integrity. Our field engineers have seen countless breakers fail due to neglecting these simple steps. A well-maintained breaker, like a well-oiled machine, performs consistently and reliably.

Expert Insight: The Future of Hydraulic Breaker Performance

We observe a clear trend towards more efficient and powerful hydraulic breakers, driven by the need for higher productivity and reduced operational costs. Our BLT-155 model, with a ‘Chisel Diameter’ of 155mm and an ‘Impact Rate’ of 200~300bpm, exemplifies this direction. We focus on optimizing the interplay between ‘Operating Pressure’ (200~220bar for BLT-155) and impact frequency to deliver maximum breaking force with minimal energy consumption. This optimization not only enhances breaking power but also extends the lifespan of the breaker and its components, such as the Piston Control Valve and the Accumulator. We anticipate further advancements in material science and hydraulic control systems, leading to even lighter yet more powerful units. This will allow for greater versatility and adaptability across a broader range of carrier machines and applications.
