Caterpillar has introduced two new rotary cutter attachments for excavators – the Cat RC20 and RC30 – which are designed for controlled demolition, tunneling, and trenching in limited places. The new cutters provide a better alternative to overworking a bucket, as they quickly and thoroughly disintegrate tough materials like concrete and asphalt, protecting the excavator buckets from damage.
Features and Specifications
The Cat RC20 and RC30 rotary cutters come with a high-torque, direct-drive motor that provides strong performance at a relatively low noise level, making them ideal for use in sensitive locations such as hospitals and residential areas. The attachments can be used with pin-on, S-type, Cat pin grabber, or CW couplers and are compatible with Cat hydromechanical work tool brackets. Their cutter choices may be changed quickly and easily with a tool.
The RC20 and RC30 cutters can be manually rotated 90 or 270 degrees, or they can be hydraulically rotated 180 degrees. In the latter mode, the cutter can operate independently of the machine. Both cutters can also be utilized for dredging tasks underwater.
The Cat RC20 is designed for excavators or tool haulers with an operational weight of between 22 and 37.5 tons, while the RC30 is designed for carriers weighing 30.9 to 55 tons. Operating hydraulic pressure for the RC20 must range from 2,466 to 5,802 psi, while the RC30 requires 2,756 to 5,802 psi of pressure.
Asset Tracking Technology
Both the Cat RC20 and RC30 cutters come with Cat’s asset tracking technology, which enables them to be tracked using a Product Link subscription and the VisionLink remote fleet management system. Owners can set up a virtual geofence boundary around the job site to notify them if a cutter is being taken away without permission.
Conclusion
The new Cat RC20 and RC30 rotary cutters provide an efficient and safe way to carry out controlled demolition, tunneling, and trenching in limited spaces. With their high-torque, direct-drive motors and compatibility with different types of couplers and brackets, these cutters can quickly and easily disintegrate tough materials like concrete and asphalt, while protecting excavator buckets from damage. Additionally, their asset tracking technology makes it easier for owners to keep track of their equipment and prevent theft.
