Darda's Hydraulic Rock and Concrete Splitters

Darda's Hydraulic Rock and Concrete Splitters
Darda Hydraulic Rock & Concrete Splitters manufactured by Darda GmbH, Germany have been used with great success in over 80 Countries for the past 4 decades for Rock Excavation, concrete demolition and Pile Cutting as they provide a powerful and extremely cost effective alternative to other conventional demolition techniques.Hydraulic Splitting means controlled splitting, and this method eliminates shock waves, vibrations, dust and noise that large impact tools usually produce. Darda Rock and Concrete Splitter has proven to be the best alternative specially where Rock hammers produce vibrations and takes long time for Pile Cutting.

Darda Hydraulic Rock and Concrete Splitters work according to the safe and proven wedge principle. First of all, a hole is drilled to a specified diameter and depth using an ordinary rock drill. Then the wedge set is inserted into the hole with the wedge in retracted position.

The hydraulic pressure then forces the wedge between the two counter wedges, pressing them against the walls of the drilled hole. The effective splitting force of up to 413 Tons or 4048 KN breaks concrete and rock from the inside, breaking thinner iron rods at the same time.

The Splitters are easy to operate, low maintenance, extremely versatile, durable–many of its customers are using Splitters for the past 10 years, easy to transport. Available in different models for different applications like:
  • Removal of Overburden in natural stone industry–Granite, Marble, Sandstone etc.
