The Critical Role of Hydraulic Breakers in Demolition
In demolition, the primary objective is to break down structures safely and efficiently. Hydraulic breakers for demolition achieve this by converting hydraulic power from a carrier into kinetic energy, delivered as repeated impacts to a working tool. This process is far more controlled and powerful than traditional methods, allowing for targeted breaking of concrete slabs, reinforced structures, and various types of rock formations. The effectiveness of a hydraulic breaker directly impacts project timelines and costs, making its selection and operation a crucial consideration for any demolition contractor.
Choosing the Right Hydraulic Breaker for Demolition Projects
Selecting the appropriate hydraulic breaker requires a detailed understanding of the project’s scope, the materials to be broken, and the capabilities of the available carrier equipment. Mismatching a breaker to an excavator can lead to reduced efficiency, increased wear on both machines, and potential safety hazards.
Understanding Carrier Compatibility
The most fundamental aspect of selection is matching the hydraulic breaker to the carrier operating weight. An undersized breaker will lack the power for heavy-duty tasks, while an oversized one can strain the excavator’s hydraulic system and structural integrity. For instance, our BLT-155 model is designed for excavators ranging from 27 to 33 tons, ensuring optimal power transfer and stability. Conversely, smaller excavators, such as those weighing 0.5-1.2t, are best paired with models like our BLT-40.
Impact Rate and Operating Pressure: The Power Equation
The impact rate (measured in BPM) and operating pressure (in bar or MPa) are key technical specifications that dictate a breaker’s power and speed. A higher impact rate generally translates to faster breaking, especially in softer materials, while higher operating pressure indicates greater force per blow, essential for tougher materials. For example, our BLT-155 operates with an impact rate of 200-300bpm and an operating pressure of 200-220bar, providing a balanced combination of speed and power for demanding demolition tasks. This balance ensures that the breaker can efficiently tackle various materials without excessive stress on the system.
Selecting the Optimal Working Tool
The choice of working tool significantly affects demolition efficiency. Different tools are designed for specific applications:
- MOIL POINT: The most common tool, ideal for general rock and concrete breaking due to its focused penetration.
- NARROW CHISEL: Suitable for cutting and trenching, particularly effective in breaking asphalt or frozen ground.
- BLUNT TOOL: Used for secondary breaking of large boulders or for compaction, distributing impact force over a wider area.
Using the correct tool minimizes wear on the breaker and maximizes material breakdown. Furthermore, a Forging Tool offers enhanced strength and wear resistance, prolonging tool life in abrasive conditions.

From Our Field Engineers: Real-World Demolition Scenarios
Our field engineers frequently encounter diverse demolition challenges. One common issue is breaking heavily reinforced concrete. For such tasks, we consistently recommend a hydraulic breaker with a high operating pressure and a robust Moil Point. For example, on a recent bridge demolition project, our BLT-140, mounted on a 22-ton excavator, demonstrated its ability to efficiently cut through thick concrete sections reinforced with rebar. The combination of its 160-180bar working pressure and a well-maintained Moil Point allowed for precise and rapid material breakdown, minimizing secondary breaking requirements. This practical application underscores the importance of matching the breaker’s capabilities to the material’s resistance.
Expert Insight: Optimizing Performance and Longevity
Effective demolition relies on more than just raw power; it requires a deep understanding of how to optimize equipment performance and ensure its longevity. We have observed that the combination of high impact frequency and stable operating pressure is paramount for efficient and economical demolition. Our BLT-155 model, with an impact rate of 200-300bpm and an operating pressure of 200-220bar, exemplifies this principle. These specifications are not merely numbers; they represent a carefully calibrated system that delivers sustained, powerful blows, translating directly into faster material breakdown and reduced project durations. This capability minimizes fuel consumption and operator hours, offering a significant return on investment. Choosing a hydraulic breaker that consistently maintains these critical performance metrics is foundational to project success, and our products are engineered precisely for this purpose.
