How Does the Hydraulic Hammer Work on an Excavator?

Excavator parts professionals often need a precise understanding of hydraulic hammer operation. Knowing how does the hydraulic hammer work on an excavator boosts part selection, troubleshooting, and maintenance. This guide explains the core mechanism and essential aspects, providing quick reference for onsite solutions and efficient part management.

Key Function of Hydraulic Hammers

- Hydraulic hammers (also known as breakers) are attachments used to break concrete, rocks, and other hard materials in excavation and demolition.

- They rely on the excavator’s hydraulic system to generate high impact force.

- Efficient design optimizes productivity and reduces downtime on job sites.

Primary Components

- Hammer Body: Encases all internal mechanisms and absorbs energy from impacts.

- Tool (Chisel, Moil, or Blunt): The contact point that delivers force to the material.

- Accumulator: Stores hydraulic energy and maintains consistent pressure for smooth hammer operation.

- Piston: Moves rapidly under hydraulic pressure to create impact force.

- Hydraulic Inlet & Outlet: Connect the hammer to the excavator’s hydraulic lines.

Operation Principle

- Hydraulic oil is supplied by the excavator’s pump to the hydraulic hammer.

- The pressurized oil moves the piston in a repeated up-and-down motion.

- Energy stored in the accumulator is released, propelling the piston downward.

- The piston strikes the tool, transferring force to the material.

- The cycle repeats rapidly (up to 1,200 blows per minute), allowing efficient breaking.

Advantages for Excavator Work

- Delivers precise, high-energy impact with controlled force.

- Reduces manual labor and speeds up demolition/groundwork.

- Minimizes machine wear with proper sizing and maintenance.

- Compatible with multiple tool types for various applications.

Maintenance & Troubleshooting Tips

- Regularly inspect hydraulic hoses and seals for leaks.

- Monitor accumulator pressure; underperformance may indicate low pressure.

- Check tool condition—sharp or blunt edges affect hammer efficiency.

- Use correct flow and pressure settings to avoid premature part failure.

- Refer to the manufacturer’s datasheet for optimal operating parameters.
