MR Multi-ripper for excavator
The whole range: Excavator tools
Compatible interfaces: S · MS · CW · OQ · M · SW
- 11–32 tons
- Carriers: Large, Heavy
The MR multi-ripper breaks compacted ground with five legs at once rather than one point, so a single pass loosens a wider strip and leaves smaller pieces to load. It works in frozen ground, hard layers and compacted clay, prepares rock for the crusher, pulls roots in land clearing and is used for selective demolition.
Features
- High Penetration Power: The shank design breaks up hard soil, rock and frozen ground.
- Fragmentation: MR multi-rippers break the ground into pieces small enough to load with a bucket.
- Multi-Tooth Design: Five teeth break up the ground at the same time
- Soil conditions: works in frozen ground, hard layers and compacted clay
- Legs: 40 to 60 mm thick, with replaceable teeth
- Mounting: Built for the machine and quick-coupler system named in your order
- Available teeth systems: CAT J series, BYG Futura, ESCO UltraLok
