Caterpillar Work Tools has expanded its range of excavator attachments with three new multi-processor models, MP332, MP345 and, MP365, which come with new features aimed specifically at users requiring large, flexible, purpose-built tools that can handle any demolition task. The new models join the MP318 and MP324 in the Cat multi-processor range.
The design of the new multi-processors allows pairing a basic housing with up to six jaw sets. The design also boosts productivity with patent-pending features such as a new jaw locking system and the speed booster valve.Â
The new MP300 Series models are compact and designed with a high power to weight ratio. The housings used for the new tools incorporate a heavy-duty rotator that provides 360-degree movement for positioning the multi-processor at an optimum angle for any demolition situation.
In operation, when the jaws meet resistance, the integral hydraulic booster valve automatically activates. The speed-booster system combines a ‘speed’ and ‘booster’ valve and can therefore use a smaller cylinder diameter (compared with previous models), which nearly halves cycle time for jaw opening and closing. In addition, depending on the jaw set used, closing force is up to 19% higher, compared with previous-series models.
The configurations of the interchangeable jaw sets include: concrete cutter (CC), demolition (D), pulveriser (P), shear (S), universal (U), and tank shear (TS). The jaw sets are designed to be exchanged in as few as 10 minutes using basic tools. Larger models feature a pin capture system that retains the cylinder pin with the jaw to further enable fast, safe jaw exchanges.
Compared with previous designs, the jaw sets have fewer welds (fewer stress points) and more replaceable wear parts. Jaw configurations D, CC, and P benefit from parts commonality. In addition, jaw configuration P uses Cat ground engaging tools while D and CC use the same retention system as the Cat ground engaging tools.
The design of the new models provides protection for hydraulic components and hoses, including housing the motor in the frame. The design also allows ready access to the cylinder, which features a well-protected rod. The number of greasing points has been reduced, compared with previous models, simplifying routine maintenance, which entails only greasing, checking for wear, and replacing worn parts. In addition, each jaw set has a standard transport system, which simplifies moving, storing, and positioning the jaw when making exchanges.
