4. How Does an Excavator Hammer Work?
An excavator hammer is powered by the excavator’s hydraulic system. The hydraulic fluid is directed into the hammer, where it activates a piston. The piston then strikes the hammer tool, transferring force to the material being worked on. Here’s a more detailed breakdown of how this process occurs:
- Hydraulic Power:
- The excavator’s hydraulic pump generates high-pressure fluid that is delivered to the hammer. This fluid flows into the hydraulic cylinder, which drives the piston.
- Piston Action:
- Once the fluid enters the hydraulic cylinder, the piston moves forward with extreme speed, striking the hammer tool. The piston then returns to its original position, ready for the next cycle.
- Impact Force:
- Each time the piston strikes the tool, it delivers a powerful blow, applying high-impact energy to the material. This impact causes the material (rock, concrete, or asphalt) to crack or shatter.
- Tool Attachment:
- The tool (usually a chisel or blunt tip) focuses the impact energy. The tool’s material and shape are critical in ensuring efficient breaking. For example, a chisel point is best suited for rock, while a blunt point is effective for softer materials like asphalt.
- Multiple Impact Strikes:
- The hammer works through repetitive strikes. Depending on the power and size of the hammer, it can strike anywhere from 300 to 1000 times per minute, making it a highly effective tool for continuous work.
