Excavator drilling splitter is a specialized engineering unit that integrates a Down-The-Hole (DTH) percussion drill with a hydraulic splitting system. The operational process involves drilling precision holes followed by the insertion of hydraulic splitting cylinders. By utilizing massive hydraulic expansion force, the drilling splitter efficiently fractures rock or concrete from the inside out.

Designed for excavator mounting, the excavator drilling splitter leverages the excavator’s mobility and existing auxiliary hydraulic circuits. By connecting a dedicated hydraulic conversion device, removing the bucket, and installing a diesel-driven air compressor at the rear counterweight position, the excavator is converted into a pneumatic rock drilling and splitting unit, enabling multi-functional operation with a single machine.

• Efficiency Integrated Operation: A single splitter unit completes the entire drilling and splitting cycle without the need for equipment changes. Seamless process transitions significantly enhance overall construction productivity.
• Superior Safety Standards: As a non-explosive operation, it eliminates the risks of explosives and flying debris. The process is fully controllable and ideal for projects in blasting-restricted or sensitive zones.
• Environmental Profile: Engineered for low noise and minimal vibration with zero harmful gas emissions. It fully complies with stringent environmental regulations and urban construction noise ordinances.
• Cost-Efficiency: Eliminates the need for costly blasting permits or expensive chemical cracking agents. The system reduces labor requirements and maintains low operational and maintenance costs.
• Diverse Versatility: Highly adaptable to a diverse range of applications, including open-pit quarrying, foundation demolition, steel slag removal, and reinforced concrete deconstruction. It provides flexible performance even in the most complex geological conditions.
