Additional Notes

  • The Caterpillar (Cat) H155 is a heavy-duty hydraulic breaker engineered for 30–40 ton class large excavators. With a massive impact energy of 6500J and a variable frequency of 300–450 bpm, it delivers outstanding breaking power for the most demanding applications, including large-scale concrete structure demolition, hard rock quarrying, deep foundation excavation, and major highway construction.
  • Equipped with a fully enclosed silenced housing, automatic anti-blank firing (ASO) protection, central auto-lubrication, and an ultra-strong reinforced structure, the H155 ensures maximum durability, low maintenance, and exceptional reliability in continuous heavy-load, high-stress conditions. It is fully optimized for seamless integration with Cat 30–40 ton excavators, maximizing hydraulic efficiency and service life even in the toughest job sites.
  • The H155 is designed exclusively for 30–40 ton excavators; improper carrier matching will result in significant performance loss and potential equipment damage.
  • With a substantial operating weight of 2499 kg, ensure sufficient lifting capacity and secure mounting during assembly and disassembly. Use only Cat-approved heavy-duty brackets.
  • Daily inspection of the auto-lubrication system and tool wear is critical to maintain stable impact performance and extend the service life of critical components.
  • Avoid prolonged dry firing or idling to prevent internal structural wear and premature failure. This model is specifically engineered for heavy-duty use only.
