Caterpillar Unveils Precision Rotary Cutters for 20-50 Ton Excavators

18 May 2023 CW Team

According to Tom Munch, Caterpillar applications specialist, the numbers in the tool names indicate the minimum machine size in tons for optimal attachment. The RC20 is designed for 320s through 330s, while the RC30 is compatible with 326 up to 340 excavators. In the first quarter of 2024, Cat plans to release additional models for the 311 to 320 and 340 and above, expanding their excavator offerings. Munch emphasized the importance of matching Cat work tools to the appropriate machine size for safety and stability.

The RC20 is suitable for 20- to 34-ton excavators, while the RC30 is designed for 28- to 50-ton excavators. These rotary cutters are compatible with Cat hydro-mechanical work tool brackets, enabling smooth transition between tasks. They can be manually turned either 90 or 270 degrees, and with an optional hydraulic lines kit, they can rotate up to 180 degrees. This feature facilitates cleaning narrow trenches or working away from the machine, enhancing productivity. Notably, the cutters can be used underwater without requiring modifications to the tool or machine. Rotary cutters find applications in trenching, profiling rock and cement walls, tunneling, quarrying, primary demolition, and underwater work.

In summary, Caterpillar's new rotary cutters for excavators provide controlled breaking and high precision, making them ideal for confined or urban areas. They offer compatibility with various attachment types and can be smoothly integrated into workflow. With their versatility and ability to operate underwater, these rotary cutters expand the range of applications for excavator operations.

Caterpillar unveiled new rotary cutter attachments for 20- to 50-ton excavators at ConExpo-Con/Agg 2023. These rotary cutters offer controlled breaking and high precision, making them well-suited for working in confined or urban areas. Unlike louder breaking tools, the rotary cutters provide a more controlled and precise operation. The Cat RC20 and RC30 models can be used with pin-on, S-type, Cat pin grabbers, or CW couplers.According to Tom Munch, Caterpillar applications specialist, the numbers in the tool names indicate the minimum machine size in tons for optimal attachment.
