Today’s tutorial covers the essentials of using a hydraulic hammer effectively. Although the hydraulic breaker might seem straightforward, mastering it involves some specific techniques. Here’s how to get the most out of this powerful tool.
1. Understanding the Hydraulic Hammer
A hydraulic hammer is designed to break and demolish tough materials. It consists of a heavy, impactful shank that is crucial for effective operation. This shank, which extends from the bottom of the hammer, is both expensive and delicate. Avoiding damage to the shank is critical.
2. Proper Setup
Before you start, ensure that your hydraulic breaker is correctly attached to the excavator. This involves:
Using Quick Couplers: Make sure the quick couplers are clean and securely attached.
Adjusting the Top Cap: The top cap, which connects the breaker to the machine, should be level. Proper alignment ensures maximum downforce and efficiency.
3. Techniques for Effective Operation
Positioning and Angle:
Maintain Perpendicularity: For optimal performance, keep the hammer perpendicular to the surface you are breaking. This alignment allows for maximum force application.
Avoid Shallow Angles: A shallow angle can cause the breaker to scoot across the surface rather than breaking material effectively.
Pressure and Engagement:
Apply Down Pressure: When using the hammer, ensure that it is firmly pressed down onto the material. This setup helps engage the hammer properly and prevents damage.
Avoid Lifting Off the Ground: Lifting the excavator off the ground does not increase efficiency. Instead, it places undue stress on the machine and can lead to damage.
4. Handling Common Issues
Getting Stuck:
Avoid Excessive Force: If the hammer gets wedged or stuck, avoid cranking aggressively. Instead, adjust the alignment by curling or extending the excavator’s boom. This adjustment can help relieve pressure and ease the breaker out of the hole.
Flexing the Shank:
Proper Use: Never use the hammer to pull or pry material aggressively, as this can bend or snap the shank. Always work the hammer in a straight up-and-down motion to avoid unnecessary stress.
5. Additional Tips
Avoid Dry-Firing:
Engage Properly: Ensure that the hammer is in contact with the material before engaging hydraulics. Dry-firing, or activating the breaker without contact, can cause damage.
Dealing with Alignment Issues:
Adjust as Needed: If the hammer isn’t aligning correctly, make minor adjustments to the bucket angle or the boom position. This will help ensure effective impact and operation.
6. End
Using a hydraulic breaker effectively requires practice and attention to detail. By maintaining proper alignment, applying correct down pressure, and avoiding excessive force, you can maximize the hammer’s efficiency and lifespan. Remember, the key to successful operation is understanding the dynamics of the hammer and making precise adjustments as needed.
