Built for the Job: Inside a DOZCO Hydraulic Rock Breaker

Rock Breaker Parts and Their Functions
A rock breaker is made of different parts, including:
- Cap Bracket: It secures the breaker to the carrier machine and ensures stable attachment.
- Frame: The outer housing that protects internal components from external damage.
- BH-Supporter: It provides structural support and maintains proper alignment of internal parts.
- Upper Damper: Absorbs vibration generated during operation to reduce stress on the machine.
- Side Damper: Minimizes lateral shock and enhances overall stability.
- Main Body: Contains the piston, cylinder, and other core components that generate impact force.
- Bottom Damper: Reduces shock transmission to the tool and improves durability.
- Window Cover: Helps with inspection and access to internal components for maintenance.
