New Cat multi-processors feature quick change jaws and other features

Published 7/3 at 17:05

The three new Cat MP332, MP345, and MP365 multi-processor models are heavy duty, high production tools that accept multiple interchangeable jaws for taking on a variety of specialised demolition tasks.

The new models, compared with previous models, can cycle 50% faster and generate up to 19% greater cutting/crushing forces. An innovative locking system enables a single operator to typically change jaw types in 15min or less using only standard hand tools, with an included stand securely and stably holding unused jaw sets.

The new models comprises of a concrete cutter with the outer jaw cracking concrete, and inner jaw shears for steel. The demolition model cracks thick concrete structures; the pulveriser crushes concrete and separates rebar, whilst the shear cuts structural steel, pipe and cabling. The tank shear cleanly cuts tanks or plate steel at right angle on three sides, whereas the universal cuts steel and crushes concrete.

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 460t-1,270t.

The design of the new models results in greater power when installed on small excavators, and the balanced design also keeps the centre of gravity close to the host machine. As an added benefit, control programmes for the tools are incorporated into the operator displays of Cat Next Generation excavator models. To ensure long term durability, jaws are protected with easily replaced wear parts. An armoured 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.
