Rock Straight System ● Features

Hard Rock

● Automated — The fully automated continuous cut- ting, loading and hauling operation optimizes the process flow and makes hard rock cutting more effi- cient by shortening the excavation cycle. ● Safe in Operation — Cutting of hard and highly abras- ive rock reduces or eliminates the need for explosives where it is used. Furthermore, a remote control oper- ation provides optimum comfort and safety for oper- ators, as the operator is placed in a RSPS (FOPS equivalent) certified cabin with air conditioning. This makes job conditions more attractive and lowers operating cost because fewer personnel is needed underground. ● Service and Maintenance Friendly — The modular architecture and the compactness of its components support a trouble-free handling. This results in short- ened downtimes for repair, maintenance and panel moves.

Features ● Productive — The Rock Straight System is designed for a continuous cutting operation. The combined use of the hard rock miner (cutting and loading of the material) and the face conveyor (transporting/ moving the material) represents a system for simulta- neous cutting and hauling — a fast and cost-effective solution generating greater return of investment. ● Efficient — The Rock Straight System is tailored to operate in low seam heights — it follows the seam and maximizes the output of cut hard rock material mined out, and leaves waste rock formation above the low seam untouched. ● Reduces Risks to Health and Safety — The hydrauli- cally operated hard rock miner and electrically driven hard rock conveyor significantly improve the under- ground climate and system carbon footprint.
