Three primary models (P318, P324, and P332) feature 360-degree rotation, and three secondary models (P218, P224, and P232) are fixed. Both pulverizer series are designed to fit 18- to 50-ton machines. SpeedBooster technology found in Cat Multi-Processors quickly closes the jaw when there is no load. When the jaw comes into contact with material, the SpeedBooster hydraulic valve automatically switches to power mode for maximum power. The bidirectional 360-degree rotation for the P300 series models positions the jaw to grab material from any angle for producing material properly sized for further processing. Integral rebar knives shear through pipes, rebar, and other embedded materials to improve demolition efficiency.
