ROCKAGE Hydraulic Breaker SK-Series Box v>
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-, 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.- Auto-greasing system(option).- High power combined by Hydraulic pressure and Nitrogen gas.
