Maximum power with the K-550

The double gripper tirelessly takes up the logs with a diameter of up to 55 cm and feeds them in the SuperCut chain saw. After having been cut to the desired length, the wood is passed on to the splitting unit via the hydraulic rocker in an ideal manner. With a splitting power of 41 t, the punch presses up to 18 billets through the hydraulically adjustable 2-in-1 frame knife. The OptiSplit system automatically adjusts the splitting stroke to the billet length and ensures a higher working speed.

More power for the SpaltFix K-550

Ring splitting knife for neater billets

Versatile and sturdy, the frame knives adapt to the respective application. The double-edged knife produces smooth splitting edges, the ring knife variants produce many uniform billets that are ready for the stove in one work cycle. The hydraulic splitting knife adjustment ensures splitting in the middle with every log diameter.

With the hydraulically adjustable frame knife, the SpaltFix K-550 produces up to 18 billets in one work cycle.


Directly before the splitting stroke, the optical sensor measures the log diameter, selects the ideal area of the special splitting knife and centres it.

This is what the automatic system does for you:

  • Improved firewood quality due to more uniform billets
  • Less splitting power required and less strain on machine
  • Higher user-friendliness

SplitControl also determines the processed wood volume in solid cubic metres. The timber volume measurement is only intended for internal use.
