In mining and tunnel construction as well as materials handling, extreme demands are made of people and machinery due to the high volumes that are transported. The quantities that are handled nowadays are only possible as a result of technical developments in loading and transport systems. However, as the metal content diminishes, higher volumes are needed, which in turn requires even more powerful solutions. Whether above ground (surface mining) or below, whether using continuous technology or traditional truck and shovel excavation – the key competitive criteria for the technology are always the same: outstanding reliability and safety against failure, as well as low-wearing, energy-efficient operation.

The gear components used in materials handling must withstand extremely challenging environmental conditions and service conditions. When used in belt drives, such as those found in brown-coal production, large temperature fluctuations are the order of the day. The components used in these gearboxes such as cylindrical gears are also subjected to changing, abrupt loads and vibration. Robustness and adequate load-bearing capacity are paramount requirements for these gear components, and Klingelnberg offers the system solutions for these.
