What is a hydraulic breaker used for?

• Small breakers – Primarily used for trenching, roadwork, demolition in residential areas, and building renovations.

• Medium-sized breakers – Commonly utilized for demolishing structures, urban excavations, and secondary rock breaking in quarries.

• Large breakers – Designed for heavy-duty tasks such as large-scale demolition, primary excavation in quarries, and digging foundations, tunnels, and railway passages.

Components and operation of hydraulic breakers

Hydraulic breakers are composed of a breaker unit, a protective casing equipped with shock-absorbing and vibration-damping systems, and a working tool, such as a moil or chisel point. The casing helps reduce impact forces on the carrier machine while shielding internal components, ensuring durability and efficient performance.

The breaker unit can be constructed as a single-piece monoblock design or assembled from multiple parts secured with four tie rods. Internally, it primarily consists of two moving components: a piston (or striking hammer) and a distributor, along with a tool (moil or chisel) designed to directly impact the material being broken.

Hydraulic breakers are powered by the hydraulic system of an excavator. High-pressure hydraulic fluid, or in some models, low-pressure nitrogen in the accumulator, drives the piston. The force generated by this thrust is transmitted to the top of the tool, which then delivers powerful impacts to the material below, enabling efficient demolition and excavation.

5 Tips for Proper Use of Hydraulic Breakers

• 1.Select the Right Tool for the Task

  • Choose the appropriate breaker size and tool type according to the material’s hardness and the specific application (e.g., use a moil point for general breaking and a chisel for trenching).

• 2.Ensure Correct Hydraulic Pressure and Flow

  • Set the excavator’s hydraulic system to match the breaker’s specifications to avoid damage and ensure maximum efficiency.

• 3.Follow Proper Operating Techniques

  • Maintain steady pressure and ensure the breaker is positioned correctly. Avoid using the tool as a lever or applying excessive force.

• 4.Conduct Regular Maintenance

  • Inspect and replace worn components such as bushings, seals, and chisels. Regularly check hydraulic hoses for leaks or wear, and ensure all bolts are secure.

• 5.Avoid Extended Operation Without Intervals

  • To prevent overheating, operate the breaker in short bursts and allow it to cool down periodically to maintain performance.

  • 5-Step Routine Maintenance Procedure for Hydraulic Breakers

    1. 1.Inspect Hydraulic Hoses and Connections

       • Check all hydraulic hoses and connections for wear, leaks, or damage. Ensure they are securely fastened and replace any damaged hoses to prevent fluid loss and maintain pressure.

    2. 2.Examine the Breaker Tool (Chisel/Moil Point)

       • Regularly inspect the tool for signs of wear, cracks, or damage. Replace the tool when it becomes worn out or damaged to ensure efficient operation.

    3. 3.Check and Replace Seals and Bushings

       • Inspect seals and bushings for wear or leakage. Replace them as needed to avoid hydraulic fluid loss and prevent internal damage to the breaker unit.

    4. 4.Lubricate Moving Parts

       • Grease the moving components, such as the piston and bushings, to reduce friction and prevent wear. Follow the manufacturer’s recommendations for lubrication intervals and types of grease.

    5. 5.Inspect and Tighten Fasteners

       • Check all bolts and fasteners for tightness. Loose components can lead to malfunctions or damage, so ensure that all parts are secure and properly tightened.
