Caterpillar’s newest multi-processor models are here, delivering heavy-duty results with their 19 percent greater cutting/crushing forces and their 50 percent faster cycle times than previous models. The MP332, MP345, and MP365 feature multiple interchangeable jaws, each with their own storage stand, that can perform a variety of high-production, specialized tasks for demolition purposes. Additionally, their innovative locking system allows a single operator to change jaws with only standard hand tools within 15 minutes or less.
Quick-Change Jaw Selections
Concrete Cutter: outer jaw cracks concrete, inner jaw shears steel
Demolition: cracks thick concrete structures
Pulverizer: crushes concrete, separates rebar
Shear: cuts structural steel, pipe, cable
Tank Shear: cleanly cuts tanks or plate steel at right angle on three sides
Universal: cuts steel and crushes concrete
Fast, powerful, efficient
The new multi-processor models are designed with "speed-booster" technology that automatically shifts hydraulic action between force (boost mode) and speed (speed mode) as operating conditions vary, resulting in optimum efficiency and productivity. Under no-load conditions, the speed valve allows high hydraulic flow to rapidly open the jaw or close it to contact. At material contact, maximum cutting/crushing force is applied. Depending on the multi-processor model and jaw being used, forces range from approximately 460 to 1,270 tons.
The design of the new models results in greater power when installed on small excavators, and the balanced design also keeps the center of gravity close to the host machine. As an added benefit, control programs for the tools are incorporated into the operator displays of Cat Next Gen excavator models.
To ensure long-term durability, jaws are protected with easily replaced wear parts. An armored cylinder rod and a protective structure for the main body of the cylinder ensure that this critical component is kept from harm even when the jaw is deep into debris. Most cutting blades can be flipped in two ways, allowing four cutting edges to be used before replacement is required. This design lowers operating costs and keeps service time to a minimum.
