Caterpillar introduced two new rotary cutter attachments for demolition and controlled trenching in confined spaces at ConExpo-Con/Agg 2023.
Not as loud as other breaking tools, rotary cutters create a more controlled breaking with high precision making them ideal for working in confined or urban areas.
The new Cat RC20 and RC30 models are available to be used with pin-on, S-type, Cat pin grabbers, or CW couplers.
Tom Munch, Caterpillar applications specialist, noted that the numbers in the nomenclature represent the low end of the machine size in tons that the tools are meant to be attached to. “Your RC20 is going to go on 320s through 330s, and the RC30 is going to be hooked to 326 up to 340,” he said.
Munch noted that in the Q1 of 2024, Cat will release additional models to fit the 311 to 320 and 340 and up to complete the excavator offerings.
“To me, the most important specs within any Cat work tool going on a Cat machine is to put them on the proper size machine for safety and stability of the configuration,” Munch said.
For the new rotary cutters, he said, the RC20 is intended for 20- to 34-ton excavators, and the RC30 fits the 28- to 50-ton excavators.
