What Is an Excavator Concrete Breaker?
An excavator concrete breaker is a hydraulic attachment. You mount it onto an excavator arm in place of a bucket. The tool uses the carrier’s hydraulic system to drive a piston. This piston strikes a chisel with great force. As a result, the chisel breaks hard materials like reinforced concrete and granite. Operators use it for demolition, construction, and quarrying tasks. Unlike manual jackhammers, this machine completes work faster and with less labor. It also reduces worker fatigue. Our models are easy to install. You simply connect the hoses and start working. Because the tool is so effective, many firms consider it essential equipment on site.
Hydraulic Breaker Machine Components and Working Principle
First, let us look at the main parts of a hydraulic breaker.
- Piston: The piston moves rapidly inside the cylinder. It creates the impact energy needed for breaking.
- Chisel: This is the tool tip that contacts the material. We use heat-treated alloy steel to ensure a long service life.
- Accumulator: This nitrogen-filled chamber stores energy. It boosts blow power and absorbs pressure spikes.
- Cylinder and Valve System: The valve controls the oil flow. It directs oil to lift the piston and then release it for a fast downward strike.
- Housing and Bracket: The housing protects internal parts. The bracket connects the breaker to the excavator arm.
Now, here is the working principle. Hydraulic oil enters the breaker from the excavator pump. The valve sends oil to the piston’s lower chamber. This pushes the piston upward and compresses the nitrogen in the accumulator. Next, the valve shifts. The compressed gas forces the piston down very fast. The piston then hits the top of the chisel. This impact transfers energy into the rock or concrete. The cycle repeats hundreds of times per minute. Our design minimizes internal wear. Therefore, you get a reliable and long-lasting tool. Furthermore, regular grease maintenance keeps the chisel in top condition.
Application Fields for Our Breakers
A rock breaker for sale from YG Machinery serves many industries. Here are the key application areas.
- Demolition: Break building foundations, bridge piers, and thick concrete walls. The tool handles reinforced concrete with ease.
- Quarrying: Extract stone blocks or perform secondary breaking. It reduces oversized boulders into transportable pieces.
- Road Construction: Remove old asphalt pavement and concrete roads for resurfacing. It also helps with trenching in hard ground.
- Landscaping and Site Preparation: Clear rock obstacles and prepare uneven land. Compact models fit mini excavators perfectly.
No matter your task, we have a model to match your needs. Moreover, all our breakers work efficiently with standard hydraulic systems.

These advantages make your investment secure and profitable.
FAQ About Our Breaker Attachments
Here are common questions about our breaker attachments.
A1: Match the carrier weight. First, check your excavator’s operating weight. Then, look at our parameter table. For example, a 10-ton excavator works well with the YG100 model. Choosing the correct size prevents damage and improves efficiency. Therefore, contact us if you are unsure, and we will help.
A2: Use standard anti-wear hydraulic oil #46 or #68. The exact grade depends on your climate. Warmer regions need #68, while cooler areas use #46. Always keep the oil clean to protect the valves. Additionally, check the oil level daily.
A3: Yes, all YG concrete breaker attachments come with a one-year warranty. This covers manufacturing defects under normal use. We also supply spare parts at affordable prices.
A4: Apply grease every two hours of continuous work. Use a high-temperature molybdenum disulfide grease. This reduces friction and prevents premature wear. Proper greasing extends the life of your breaker.
