Cat® Pulverizers are perfectly matched to Cat excavators so you can deliver productive concrete demolition without compromising performance or machine health. Cat P300 Series Primary Pulverizers are designed for applications such as cutting, breaking, and crushing concrete structures during demolition.

VERSATILITY AND CONVENIENCE WITH COUPLERS
HIGH PERFORMANCE
        
  • Cat pulverizer jaws are designed to cut through material quickly to enhance your machine’s overall operating efficiency and help reduce fuel consumption.
    •     
  • Precisely position primary pulverizer jaws with 360-degree rotation and visibility to the moveable jaw during demolition.
    •     
  • The Speed Booster valve actively balances speed and power, delivering fast cycle times and strong closing force to help increase productivity.
EASY TO MAINTAIN
HIGH PERFORMANCE
EASY TO MAINTAIN
        
  • Replaceable wear parts can be swapped quickly in the field and do not require surface welding to help reduce service time.
    •     
  • Daily wear parts inspection and grease points are accessible from the ground with the pulverizer still mounted on the machine.
    •     
  • Safely perform maintenance with easy access through one inspection panel.
    •     
  • Hydraulic components are shielded from damage inside the housing, helping decrease downtime on the job site.
RELIABILITY AND DURABILITY
EASY TO MAINTAIN
RELIABILITY AND DURABILITY
        
  • Cat pulverizers are manufactured with high-strength, abrasion-resistant steel, especially in excessive wear areas.
    •     
  • Reinforced cylinder rod hinges on the moveable jaw are designed to help boost durability and life of the pulverizer.
    •     
  • The C-shaped cylinder guard provides extra protection against concrete demolition.
    •     
  • Cat pulverizers have a versatile use across demolition applications, making them your choice for a wide variety of job sites.
