Overview
The document provides detailed technical information about DARDA hydraulic rock and concrete splitters, highlighting their specifications, applications, and advantages. These splitters offer a powerful and cost-effective alternative to conventional demolition techniques, providing controlled splitting without the adverse effects of shock waves, vibrations, dust, and noise.

Specifications
The DARDA splitters consist of three main components: splitting cylinders, a hydraulic pump unit, and high- and low-pressure hoses. The splitting cylinders are made of high-quality aluminum and steel, ensuring durability and lightweight handling. The hydraulic pump units can be powered by electric, air, diesel, or gasoline motors, with system pressure limited to 50 MPa (500 bar).

Technical Details
The splitters operate using a wedge principle, where a hole is drilled into the material, and a wedge set is inserted. Hydraulic pressure forces the wedge between counter wedges, creating a splitting force of up to 413 tons (4048 kN). This method is effective for breaking concrete and rock from the inside.

Applications
The splitters are suitable for various demolition tasks, including concrete and reinforced concrete demolition, rock demolition, tunneling, and underwater demolition. They are particularly useful in confined spaces and areas with difficult access.

Advantages
The DARDA splitters offer several advantages, including:

• Economical: Eliminates the need for blasting, reducing costs and safety risks.
• Safe: Controlled demolition with no risk of flying debris or explosions.
• Environmental-friendly: Low noise and dust emissions make them suitable for densely populated areas.
• Durable: Robust design requires minimal maintenance.
• Autonomy: Easy to transport and operate without heavy machinery.
• Precision: Allows for controlled demolition with predetermined split direction and size.

Additional Features
The document also mentions the use of special lubricants to reduce friction during the splitting process, enhancing performance by 20 to 50% compared to conventional lubricants. Enlarging counter wedges and pressure shells are available for specific applications, such as widening cracks or dealing with heavily reinforced concrete.
