Additional Notes

  • The Caterpillar (Cat) H140 is a heavy-duty hydraulic breaker engineered for 20–30 ton class medium excavators. Delivering a powerful 4500J of impact energy with a variable frequency of 350–500 bpm, it delivers exceptional breaking performance for demanding heavy-duty applications including large-scale concrete demolition, hard rock excavation, quarrying, deep foundation work, and highway construction.
  • Featuring a fully enclosed silenced housing, automatic anti-blank firing (ASO) protection, central auto-lubrication, and a reinforced high-strength structure, the H140 ensures maximum durability, low maintenance, and reliable operation in continuous high-load conditions. It is fully optimized for seamless integration with Cat 20–30 ton excavators, maximizing hydraulic efficiency and service life.
  • The H140 is designed exclusively for 20–30 ton excavators; improper carrier matching will reduce performance and risk equipment damage.
  • With a minimum operating weight of 1783 kg, ensure sufficient lifting capacity and secure mounting during assembly and disassembly.
  • Regularly inspect and maintain the auto-lubrication system and tool wear to ensure stable impact performance and extend service life.
  • Avoid prolonged dry firing or idling to prevent internal structural wear and premature component failure.
