Voith TurboBelt TT Linear Booster Drive

Voith TurboBelt TT Linear Booster Drive

Significant cost savings in belt conveyor systems with the Voith TurboBelt TT Linear Booster Drive

The Voith TurboBelt TT Linear Booster Drive is a high-performance secondary drive for belt conveyors. It extends the use of belts in existing systems, as well as increasing their capacity. In new belt conveyor systems, it reduces the requirements on belt quality leading to considerable cost savings.

The TT Drive is very well suited to belt systems that need to be lengthened or a shortened while mining raw materials. Compared to conventional secondary drive technology, the TT Drive does not need belt transfer points. This reduces the strain on the belt and increases its lifetime. Eliminating belt transfer points leads to considerably less dust. In addition, systems that use the TT Drive require less space than conventional systems. This is an important aspect in underground mining.

In lengthy belt systems, the TT Drive reduces the belt tension force so a belt of lower quality can be used saving enormous costs, for example, by using fabric belts instead of steel cord belts. Smaller drive components (motor, gearbox, pulleys, etc.) can also be used. The space required by the head drive is also less.

In existing belt conveyor systems, the TT Drive increases the conveyor capacity while keeping the drives and belts the same. In this way, the existing drives and the belt can be retained.

Mine Gains Dual Benefit from Installation of Voith TurboBelt TT Linear Booster Drives in Belt Conveyor

Voith has installed a TT Drive on the H2 belt conveyor in the Prosper-Haniel coal mine without interrupting operation and achieved a comprehensive solution with the subsequent installation of another TT Drive that resulted in sustained cost reduction for the mining company.


With more than 100 years of working with conveyor technology products in underground coal mining, we offer customized solutions for mining conveyor technology and tailor-made systems for shaft hoisting.

We are your engineering partner for:

- Design and layout of complete belt systems
- Modern belt conveyor design
- Calculation and development of belt conveyor systems in both underground and above ground mining and other industries
- Concept, design and production of bulk-material conveyor systems
- Optimization of existing belt conveyor systems
