Rock Splitter
C20 C

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.

make the
difference

Small carriers

Enormous splitting force always guaranteed regardless of input pressure.

Best power-to-weight ratio

World's strongest splitting cylinder in relation to size: 1,800 t splitting force.

Low vibration and dust almost noiseless

Use even in inhabited areas and during ongoing operation, underground as well as inside buildings.

Economical and safe

No time-consuming and cost-intensive safety measures. No flying stones – other work can continue in parallel.

Accurate splitting

Splitting direction and splitting course can be precisely determined in advance. Permanent material is spared.

Can be used under water

Due to the automatic lubrication, there are no limits.

C20 C – machine-
guided splitting

The Rock Splitter is the solution especially in urban and sensitive areas, because there is almost no noise and vibration, as well as flying rock, in comparison to conventional methods and the related safety measures, costs and delays.

It is especially suitable for narrow applications such as trenching or foundation work, as well as rock quarrying and block extraction of natural stone in open-cast mines, since other work can continue in parallel at any time.
The rock is not pulverized by the splitting technique. The cohesion of the material remains given and the production of larger split pieces guarantee with more volume per borehole highest productivity under safe conditions.

The pendular Rock Splitter can be attached to almost any hydraulic boom with a chain, making it very adaptable and it constantly aligns itself with gravity.
