Cat introduces rotary cutters for precision controlled breaking in trenching, tunnelling and demolition applications

New RC20 and RC30 models offer high torque with low noise and are compatible with Cat VisionLink tracking solution

Cat has introduced new Rotary Cutters for excavators that offer high production in hard material for applications such as trenching and demolition.

The manufacturer said in an announcement that the new Cat RC20 and RC30 models are available to be used with pin-on, S-type, Cat pin grabber or CW couplers.

Cat’s statement said that “with controlled breaking and high precision, rotary cutters are ideal for working in confined or urban areas”. It added that since rotary cutters produce lower decibels of sound compared to other breaking tools, they can be used in areas where noise levels need to be kept low - such as residential neighbourhoods or hospitals.

Cat added that the rotary cutters are compatible with its hydro-mechanical work tool brackets, which allow operators to move more smoothly from one task to the next. For space constricting jobs, the rotary cutter can be manually turned either 90 or 270 degrees. Adding an optional hydraulic lines kit, the rotary cutter can be turned up to 180 degrees for cleaning narrow trenches or working away from the machine to help get increased productivity. For dredging applications, the rotary cutter can be submerged in water without modifications to the tool.

According to Cat, the attachment’s direct drive motor offers “high torque, production and performance to help operators get the job done faster”. With less space between the drums, operators can build narrower trenches while also burning less fuel, said Cat.

When it comes to maintenance, rotary cutter picks are easily replaced with a simple tool and can be switched out quickly. Maintenance panels also offer quick and easy access and mechanical seals help to lock in grease and keep dust out to go longer between servicing. Rotary cutters break up material more to help put less wear and tear on buckets, said Cat.

The rotary cutters also fall within Cat’s telematics systems and attachments with asset tracking can be viewed within Cat VisionLink alongside the brand’s Product Link subscribed equipment, enabling operators to track their entire fleet of attachments and machines from one source. Attachments with an asset tracker send an alert if they leave an easy-to-setup site boundary to help keep tools more secure, explained Cat.
