Hydraulic Breaker

CP hydraulic breakers range from flexible, lightweight models up to super heavy duty models. Whatever the job, large or small, light or heavy, CP has the right tool in its breaker range.

 The slim designs of CP hydraulic breakers give a good line of sight to the working tool point. The tools are well balanced, with no external side bolts and protruding machine parts that can come into contact with the operator’s body.  

 Hoses are fitted with flat face HTMA quick release couplings for fast and easy connections in all work situations. The couplings are designed to help keep hydraulic systems clean on work sites where there are large amounts of dust and dirt. 

Models with "VR" in their model name designate breakers with Vibration Reduced Handles.
