Mini Class
Carrier: 0.7-12 t
Three Components That Set a Hydraulic Breaker Apart

Red Line vs Grey Line
Two different working principles, one superior quality.
Red Line / Hydraulic
Red Line
HKM Red Line Breakers are engineered to generate efficient solutions regardless of application. The new generation Power cell design of our Red Line provides constant impact energy for operations with maximum productivity. Reinforced buffering components, optimum piston stroke length and many more details are improved for longer and continuous operations at the most difficult conditions.
Red Line →Grey Line / Gas-Hybrid
Grey Line
Grey Line breakers are offering the simplest breaking operation with hybrid working principle. Each Grey Line breaker is engineered to operate within a wide oil flow range. This allows operating Grey Line breakers on different carriers and under different excavator pump performances. Breaker settings can be optimized based on the rock type, offering higher impact energy at lower frequency or lower impact energy at higher frequency. HKM is offering the simplest solution with Grey Line.
