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.

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).

Different splitting inserts
The predominant source material and the application requirements determine the splitting insert called wedge set. This ensures that the best splitting result is always achieved.

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.

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.

Quick-change device
Tool locking system allows quick and easy replacement of the splitting insert on the job site.

C12 – the powerful 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 largest hand-held cylinder model is the world’s most powerful splitter in relation to its size. The C12 splitting cylinder breaks reinforced, lightweight, as well as unreinforced concrete equally reliably and is particularly suitable for heading concrete piles, as well as wall and masonry demolition.

The C12 splitting cylinder is particularly suitable for rock demolition, as well as secondary splitting of boulders. Through several splits, the structure of a full rock surface or rock area can be weakened and the rock can be easily excavated afterwards. In the natural stone industry, it is used for block quarrying of hard rock, as well as in tunnel driving and extension work in underground mining.

The handy Rock and Concrete Splitter has an enormous 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.
