From the best power to the economic satisfaction with exceptional performance -
Demonstrates the true value in treating from road-construction to a mine field.
- The full box enclosure protects the hammer minimizing hammer maintenance and reduces noise.
- Dual shock absorption systems redirects blow energy to the target material, virtually eliminates recoil to carrier.
- Advanced features for toughness, simplicity and economy of operation : slim-line case, two tool retainers, custom bracket caps, single in-body accumulator, fewer parts, light weight.
- Featuring only two moving parts SK-breakers offer more "up-time" and simple, in the field maintenance. When repair is required the SK-breaker will be back on the job quickly and at a reasonable
cost.
