More power – more production
- Only NPK® offers an exclusive integrated booster system that automatically activates when the jaws meet resistance.
- C-type arms are providing maximum crushing force.
- Low weight, long reach.
- Large jaw opening (1020 mm)
- Arm/Dipperstick mounted.
- Piston rod and hoses fully protected inside the crushers frame.
- Slim-line design.
- Fast opening/closing times starting from 4.5 secs, in unloaded condition, produces 13 cycles per minute.
- Standard 360º hydraulic rotation.
- Maintenance friendly.
- Reinforced steel cutters are standard.
- Low oil flow, ensures other functions of the excavator are not influenced.
