P50 Hydraulic Breaker

The P50 Hydraulic Breaker use of advanced hydraulics, materials technology, strength calculations, impact wave theory and production technology has enabled Promac to create hydraulic hammers that are powerful, durable, cost-effective and the undisputed leaders in their class.

The P50 Hydraulic Breaker has been designed using a revolutionary new operating principle that combines stroke length, blow energy and Promac’s idle blow protector, allowing the hammer to be adjusted to match individual carriers and applications, improving hydraulic efficiency and safety.
