1

Splitting direction can be determined in advance

The splitting direction and the splitting course can be precisely determined via the control valve on the upper handle.

2

Hydraulic hoses with burst protection

Robust multi-layer hoses reliably connect the splitting cylinder to the high-pressure hydraulic power unit, which delivers a system pressure of 50 MPa (500 bar).

3

Rugged design

Components made of the highest quality aluminum and steel materials guarantee a very long service life even under the hardest conditions. Maintenance work is almost obsolete.

4

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.

Can be used independently everywhere

Independent of carrier equipment. Demolition in hard-to-reach places, in confined spaces – even under water.

Powerful in seconds

Splits in seconds with 195 t splitting force.

Low vibration and dust, almost noiseless

Can also be used in inhabited areas, enclosed spaces and during ongoing operations, both underground and indoors.

Economical and safe

No time-consuming and costly safety measures. No flying rocks – other work can continue in parallel.

Precise measurement can be controlled at any time

Direction and course of splitting can be precisely determined in advance. Permanent material is spared.

Robust and light

Hardest applications and only one person needed for transport and operation.

C2S – the smallest
Splitter

Taking advantage of the low tensile strength of rock and concrete, the hydraulic splitting cylinders allow controlled, quiet and cost-effective demolition from the inside!

Our smallest cylinder model is predominantly used in the demolition of rock and natural stone during press pipe jacking. However, the C2 splitting unit is also suitable for secondary splitting of boulders, expansion in underground mining, knapping work, as well as block extraction of hard rock in the natural stone industry.

The handy Rock and Concrete Splitter has a tremendous power-to-weight ratio. One person can work in any position and even under water, while other work continues in parallel: Low noise, without vibrations and flying rocks.

Functional
principle of the
Hydraulic Rock
and Concrete
Splitters

Conventional mechanical methods destroy the structure of the material by applying external force. Rock and concrete, however, can withstand very large compressive forces from the outside. In comparison, the resistance to a force acting from the inside out is relatively low. The development of the Darda Rock and Concrete Splitter was based on this fact.

Safe wedge
principle

First, a hole of the appropriate depth and diameter is drilled, into which the splitting insert of the splitting cylinder is then inserted and aligned to determine the splitting direction. With hydraulic pressure, the wedge pushes itself between the two counter wedges and presses them apart. The effective splitting force of up to 413 tons or 4048 kN destroys the structure of concrete and rock from the inside. A split is created in a matter of seconds. Thinner reinforcing bars in reinforced concrete tear off.
