Sterling Ripper
Vibratory ripper for excavators: quiet rock breaking without the shock load that a hydraulic breaker puts on the machine and the operator. Used in construction, quarrying, mining and tunnelling. Tooth, chisel and compactor tools are available, so the same unit can also compact the ground.

- Higher productivity than hydraulic breakers: 2 to 8 times greater productivity depending on rock type
- Three tools for one ripper: chisel type for hard rock, tooth type for soft to medium-hard rock, compactor type for ground compaction; the tool can be changed on site
- Minimal vibration to excavator and operator thanks to the unique Cartilage-Link structure
- Low noise: the Cartilage-Link structure keeps noise levels below 90 dB, enabling use in downtown construction zones
- Easy on-site maintenance: most parts are replaceable directly at the job site, fewer parts than competitors
- Centered double eccentric weights for better durability of bearings
