Piston rock splitter
Piston rock splitter is a new-generation rock-breaking device inspired by hydraulic jack design. Targeting the limitation of handheld wedge splitters in large-scale rock removal, it’s the optimal solution for such projects. Boasting far greater power and higher efficiency than handheld wedge types, it perfectly meets the demands of large-scale rock-breaking construction with stable and reliable performa.

Real-world Use Cases
Application Scenes
The core application scenarios are static demolition of hard rock/concrete works with strict restrictions on vibration, dust and noise, replacing traditional blasting and hydraulic breakers. Typical fields include：
1 mine mining,
2building demolition,
3municipal construction and emergency rescue, especially suitable for special environments such as cities, protected areas and precision factories.

How It Works
Product Principle
Concrete and rock possess highly anti-compressive strength but lowly tensile strength.Therefore,piston rock splitters exploy the feature. The hydraulic pump station drives the piston inside the splitting rod to extend outward, which expands and cracks the rock. With the splitting force thousands of tons, it is easy to split hard rock from the interior in approximately two minutes and ensure the object splits in the predetermined direction.
