How Does a Hydraulic Breaker Work?

The piston is typically set at the bottom dead center, with the mandrel free to move. The striking piston is raised by the high-pressure oil acting on the lower working surface of the piston head, which keeps moving upward until it shuts down the outlet gap in the upper position.

The piston head’s high-pressure oil consumes the energy storage which is the nitrogen gas in the tank. The stored energy in the energy conversion system is released when the exhaust valve opens, pressing the percussion piston downward with massive force.

The ecavator’s hydraulic system supplies the hydraulic breaker with the hydraulic oil, which is a prerequisite for the hydraulic breaker to function.

A hydraulic breaker includes the front head, back head and cylinder. There are usually 3 types hydraulic breaker for your choice according to the shapes, Silenced type hydraulic breaker, Open top hydraulic breaker and side type hydraulic breakers.

Piston and Cylinder: The hydraulic breaker houses a piston that moves within a cylindrical housing. The hydraulic oil pressure, which is supplied through the control valve, facilitates the reciprocal movement of the piston.

Striking: When the piston is propelled forward due to hydraulic pressure, it strikes the chisel or the tool fitted to the breaker, thus creating a high-energy impact to break materials such as concrete, rock, etc.

Nitrogen Gas Chamber, we also called back head: Some hydraulic breakers have a nitrogen gas chamber, which works as a cushion absorbing the recoil forces and reducing stress on the excavator.

Chisel: The chisel is the part of the hydraulic breaker that comes into directly. It can come in various shapes and sizes, catering to different applications, and they are replaceable.

Frequency and Energy Regulation: Modern hydraulic breakers come with variable frequency and energy regulation systems, allowing operators to adjust the striking frequency and energy as per the hardness of the material to be broken.

How to use a hydraulic breaker?

Step 1: Installation

First and foremost, the hydraulic breaker should be correctly installed on the excavator or the carrier machine. Ensure all connections are tight and that the breaker is securely attached to avoid accidents during operations.

Step 2: Pre-operation Checklist

Before commencing with the operations, perform a routine check on the hydraulic breaker and the carrier machine. Check the hydraulic oil level, and the condition of the chisel, and ensure that all nuts and bolts are tightened adequately.

Step 3: Positioning

Place the carrier machine in a stable position. The breaker should be positioned perpendicularly to the material that needs to be broken to achieve the best results.

Step 4: Starting the Breaker

Activate the hydraulic breaker by starting the hydraulic flow from the carrier machine. The breaker should start with a moderate speed to prevent bouncing off the working surface.

Step 5: Breaking Process

Apply a steady pressure and allow the breaker to penetrate the material slowly. It is advised to start from the edges of the material and work your way towards the center for an effective breaking process.

Step 6: Controlled Operation

Operate the breaker with controlled movements. Avoid applying excessive force as it might damage the chisel and the breaker. Furthermore, periodic cooling breaks should be taken to prevent overheating of the breaker.

Step 7: Maintenance

After the operation, carry out a post-operation check. Regular maintenance, including greasing and checking the wear and tear of the chisel and other components, is vital for the longevity of the hydraulic breaker. More information, please refer to the manual book

What is the difference between pneumatic and hydraulic breakers?

Absolutely, distinguishing between pneumatic and hydraulic breakers is crucial in navigating the decision-making terrain in construction projects. Here we delineate the primary differences between the two:

  1. Power Source
  • Pneumatic Breakers

Powered by compressed air generated by an external compressor.

Require a steady air supply, necessitating a continuous connection to the compressor.

  • Hydraulic Breakers

Utilize hydraulic fluid, powered typically by the hydraulic system of the carrier machine or a separate hydraulic power unit.

They harness the power of fluid mechanics, ensuring a stable and potent power source.

  1. Efficiency and Power Output
  • Pneumatic Breakers

Generally offer lower power output compared to hydraulic counterparts, rendering them more suitable for medium to light-duty tasks.

  • Hydraulic Breakers

Have a substantial power output, aligning them with heavy-duty operations such as breaking robust rocks and demolishing substantial structures.

As a choice of an adept hydraulic breaker supplier, they are crafted to deliver superior efficiency and higher impact energy.

  1. Versatility and Application
  • Pneumatic Breakers

Often lighter and more portable, proving handy for operations in confined spaces or for lighter duties.

Can be handheld, affording more control and maneuverability in certain applications.

  • Hydraulic Breakers

Boast of a more extensive range of applications, being compatible with a diverse array of carrier machines, including various excavators and skid steer loaders.

Offer more considerable versatility, grappling efficiently with a broad spectrum of tasks, from breaking rocks to trenching and other intensive construction operations.

  1. Maintenance and Durability
  • Pneumatic Breakers

Have a relatively simpler construction, which often translates to lesser maintenance requirements and breakdowns.

  • Hydraulic Breakers

Require regular maintenance checks to uphold optimal performance levels and longevity.

When sourced from a reliable hydraulic breaker supplier, they demonstrate remarkable resilience and endurance in tough working conditions, promising a longer lifespan.

  1. Investment and Operational Costs
  • Pneumatic Breakers

Generally come with a lower initial cost but might incur higher operational costs over time due to lower efficiency.

  • Hydraulic Breakers

Might entail a higher upfront investment, but their superior efficiency and productivity often translate to more cost-effective operations in the long run.

What is the size of hydraulic breaker?

  1. Weight Classification

Hydraulic breakers are often categorized based on their weight, which roughly translates to their size and power:

Small Breakers: Generally weigh between 120 to 500 kg. These are ideal for minor breaking operations and are often paired with small excavators or skid steer loaders.

Medium Breakers: Their weight ranges from 500 to 2000 kg, suitable for a wide array of moderate-duty applications, often partnered with medium-sized excavators.

Large Breakers: Weigh over 2000 kg and are used for heavy-duty tasks involving large excavators, and are perfect for breaking hard materials in large-scale projects.

  1. Tool Diameter

The tool diameter also plays a pivotal role in determining the breaker size, with larger diameters facilitating more substantial breaking force:

Small Diameter Tools: Suitable for delicate operations where precision is a priority.

Large Diameter Tools: Employed in operations where a higher breaking force is needed, generally in heavy-duty applications.

  1. Expert Advice

It is prudent to consult with a hydraulic breaker supplier to secure a breaker of the right size that aligns with your carrier machine’s specifications and the demands of your operational environment. If you want to know which model hydraulic breakers are suitable for you, please contact us.
