C400 Underground Skid Frame
The C400 Underground Skid Mounted is specifically designed for diamond core drilling operations in confined underground mining environments.
Mounted on a robust skid frame, the system consists of three main modular sections, allowing easier transportation, handling and installation in underground areas where access and working space are limited.
Its compact modular configuration provides the flexibility required for challenging underground exploration while maintaining the drilling performance, stability and reliability of the C400 platform.
