Additional Notes

  • The  Caterpillar (Cat) B8 series hydraulic breakers, including the standard B8, B8s, and B8 Side Mount variants, deliver 1150J of impact energy, engineered for medium-to-heavy duty applications.
  • Standard B8 & B8s: Designed for 6–9 ton mini excavators, 216–299 skid steer/compact track loaders, and 415–444 backhoe loaders. The B8s features a reinforced housing and optimized structure for enhanced durability in continuous heavy-duty operation, with a slightly lower weight than the standard B8.
  • B8 (Side Mount): Purpose-built for 415–444 backhoe loaders, with a dedicated side-mount bracket that maximizes visibility and maneuverability in confined spaces, while maintaining the same 1150J impact performance.
  • All B8 series breakers feature optimized hydraulic efficiency, robust low-maintenance construction, and full compatibility with Cat equipment, ensuring reliable performance and long service life across diverse job sites including concrete demolition, rock excavation, trenching, and road construction.
  • Weight variations stem from different housing structures and mounting bracket designs.
  • The B8 Side Mount variant adds 14.3kg vs the standard B8 due to its specialized side-mount hardware, tailored for backhoe loader integration.
  • All models support optional automatic lubrication systems and noise reduction housings to meet special requirements such as urban construction.
  • Seamlessly integrated with Caterpillar equipment for optimal hydraulic matching and performance.
