1. Chain – vertical operation
Chain-suspended from carrier machine. Can be attached to almost any hydraulic boom by chain suspension, which makes it very flexible. Direction constant according to the force of gravity. Definition of the splitting direction and the splitting course by second operator.
2. Internal pressure booster
Full splitting force independent of the input pressure of the carrier thus always guaranteed.
3. Integrated, automatic wedge lubrication system
Lubrication system and shut-off device guarantee lifetime and cost savings.
Factory setting allows 80 – 100 splits per filling. Lubricant quantity adjustable.
Ready for use again in the shortest possible time due to cartridge filling via rechargeable battery refill pump.

4. Length splitting insert selectable
Two possible lengths can be selected depending on the type of rock and rock composition.

5. Specially developed hardening process
Hard metal layer of the counter wedges enables the transmission
of the very high forces and provides long-lasting protection against corrosion, seizure and wear.
