How They Work
Phase 1, First, a hole of a precise diameter and depth is drilled into the material. The wedge set (one wedge and two counter wedges) is inserted into the drill-hole.
Phase 2, The wedge is driven forward under hydraulic pressure, forcing the counter wedges apart with a force of up to 400 tons. The material splits within seconds.
Phase 3, With enlarging counter wedges the split can be expanded to its maximum width. Reinforcing rods break or can be cut up with a suitable power tool, e.g. the Darda HCS 6 Combi- Shears.
The power from within
The stone and concrete splitting cylinder functions according to the proven wedge principle, whereby a strong force is applied in an extremely constricted space (from within). Rock and concrete put up considerable resistance to forces applied externally. As a result, conventional demolition methods such as hydraulic chisels or crushers are unable to demolish these materials with any worthwhile degree of control or precision. By comparison, the resistance of stone and concrete to force applied internally is 90% less, with the result that they disintegrate relatively easily.
The right combination for every job
Hydraulic power units with a variety of drive systems are available for different applications and requirements. They can produce up to 50 MPa (500 bar) maximum system pressure. All of our splitting cylinders can be combined with each of our power units. The high-quality hydraulic hose sets are designed for the strong pulsating pressures.
