Rock Splitter
C20 J

1

Joint – horizontal and vertical operation

Connected to carrier via upper mounting plate. Its alignment is not influenced by gravity. Precise definition of the splitting direction and the splitting course possible due to hydr. rotary drive. Only one machine operator required.

2

360° rotary drive

Easy positioning and setting of the splitting direction and the course of the splitting.

3

Internal pressure booster

Full splitting force independent of the input pressure of the carrier thus always guaranteed.

4

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.

5

Length splitting insert selectable

Two possible lengths can be selected depending on the type of rock and rock composition.

6

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 J – 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.

Rotatable and maneuverable, it is especially suitable for confined applications in mining and shaft sinking as well as for driving cross-cuts in tunnel construction, since it is possible to work in any position within the working radius and also overhead, and this at any time while other work continues in parallel. The rock is not pulverized by the splitting technique. The cohesion of the material remains given and the production of larger split pieces guarantee you with more volume per borehole highest productivity under safe conditions.

The fixed Rock Splitter is attached directly to the carrier via the mounting plate and its alignment is not influenced by gravity.
