Product Overview

Roof Supports

Steep grades, very thick and very thin seams, unstable roofs and massive sandstone plates, soft ground and geological faults. These varying conditions require a high level of adaptation to specific requirements.

Shearers

Maximizing productivity levels as the seam height diminishes requires a robust and compact cutting machine design with optimal coal-loading performance.

Our history goes back almost 200 years

HBT mining technology for underground coal extraction can look back on a long – almost 200-year history. Even though hard coal mining has come to an end in Germany, German technological know-how in the field of mining remains an unmistakable trademark.

Today, HBT can draw on a vast and long-standing wealth of experience gained from mastering even the most difficult geological conditions – as is partly the case in German mining.

History

Tested Quality

All research, development, design, and manufacturing are done in-house at the core HBT facilities. This ensures that all equipment meets the highest standards and international regulatory requirements. In addition to machine manufacturing, HBT produces high-quality parts and provides world-class support services for all their equipment.
