Benefits and Features

  • New speed booster technology dynamically shifts hydraulic force from speed to boost mode, automatically as you operate.
  • You’ll spend less time waiting for the jaw to open or close to contact, as the speed valve automatically adjusts to fast flow when there’s no load.
  • Maximum crushing/cutting force is applied as soon as the jaw contacts material.

  • Process more per hour, ship more per shift, make more every day. Speed booster magnifies hydraulic force when the jaw contacts material, quickly making the cut.
  • Mount more power even on smaller excavators. Compact design keeps the center of gravity as close as possible to the machine.
  • Get maximum performance and total support with a complete Cat demolition solution. Programs for the MP are built into the Next Gen Cat operator display. Single point of support your entire system by your local Cat dealer.

  • Innovative jaw locking enables a single operator to easily change jaws in 15 minutes or less. Requires only standard hand tools.
  • Simple and safe jaw changes are part of the design. Every jaw sits stable, even on the roughest work site, on the included jaw stand.
  • MP332 accepts these jaw types:
    • Concrete Cutter – outer jaw cracks concrete; inner shear jaw cuts steel
    • Demolition – opens wide to crack the largest concrete structures
    • Pulverizer – crushes concrete, separating the rebar
    • Shear – cuts structural steel, pipe, and cable

  • Protect your investment and maintain performance, quickly and economically. Jaws are protected with easily changed, individually replaceable wear parts.
  • Get more production time per cutter before replacement. Most cutting blades can be flipped in two ways, to use four different cutting edges.
  • Even when deep into debris, the cylinder rod is armored to prevent damage and the main cylinder body is protected inside the housing.
