Atlantic Robotic Spray Arm RSA 500 has emerged as a game-changing innovation in modern shotcreting applications. Engineered specifically for large and medium tunnels, underground mines, caverns, vertical surfaces, and high-slope stabilization, the RSA 500 seamlessly integrates advanced automation with rugged field-ready design.

From wet process shotcrete to dry gunite applications, and from steel fibre to polypropylene fibre concrete, the RSA 500 is the most versatile robotic spraying equipment in its class. This is the future of efficient and safe concrete application.

🏗️ Built for Harsh Environments, Optimized for Performance
With a compact body, small turning radius, and heavy-duty chassis, the RSA 500 is ideal for working in narrow tunnels, unstable slopes, and confined caverns. The integration of 4-wheel drive, 4-wheel steering, and crab mode gives it unmatched mobility even on rugged terrain.

It’s not just a machine — it’s a complete robotic shotcrete spraying system equipped with smart automation and high-precision dosing for optimal concrete application.

🔧 Product Features
