The Voith TurboBelt TT Linear Booster Drive is a powerful and productive intermediate drive for belt conveyors. It was originally developed in 1975 by Hese Maschinenfabrik and has been fi eld-proven in coal mining operations in Germany. It improves conveying effi ciency by extending the service life of belts, saving belt costs in new conveyors and increasing capacity in existing systems.

Over the last quarter-century, most underground large belt conveyors in Germany have been equipped with TT drives. The driving force behind this adoption is they offer a range of clear benefi ts:• In new systems, the use of TT Linear Booster Drives avoids

transfer points, protecting the belt and resulting in a longer service life.

• In many cases and depending on reserves, TT drives can improve the capacity of older conventional conveyors — without needing to change the existing drive or replace the belt.

• They lower belt quality requirements and, in many cases, enable the use of textile belts in operations where, under normal conditions, a steel cord belt would be necessary. This, in turn, eases splicing, handling, and repairs, there-fore reducing the running cost of the overall system.

• The ability to operate with a lesser-quality belt translates to lower running cost, as well as reduced investment in the belt — which is the single most expensive component.

TT Linear Booster Drives provide benefi ts when used with medium, long or inclining belt conveyors. They provide maximum return when used with belt conveyors of 800 m or longer, as well as with inclining or declining belt conveyors, independent of length. In terms of installed base, approxi-mately 150 conveyor systems have been equipped with TT drives, equivalent to about 300 km of aggregate length, with roughly 250 drive stations delivered.

Benefi ts Driven by Linear Thinking

and Highly Effi cient Design.

Shorten or lengthen conveyors with ease.As mining runs advance further and deeper, belt conveyors

must be either lengthened or shortened along coal haulage

pathways. To continue forward with standard equipment and

without changing the belt performance characteristics, the

only method until recently was to separate the conveyor dis-

tance into several short conveying plants.

With Voith TurboBelt TT Linear Booster Drives, such a con-

veying run can be continuously operated from charging to

discharging, without the need for increased belt stability — and

drive units can remain in standard sizes. An added benefi t is

that with fewer transfer points, belts are protected from extra

stress and there is less dust formation. Moreover, TT drives

require less installation space than conventional systems with

transfer points.

Boost belt conveyors to meet increased performance demands.TT drives are ideally suited for use with high power drift

conveyors and overland conveyors. While conventional

systems often need to rely on steel cord belts with large drive

units, a system with TT drives can reduce belt quality require-

ments. This often enables usage of more cost-effective textile

belts and smaller drive units; e.g. pulleys, gearbox, standard-

size motors.  In addition, the space required for the head

drive is considerably smaller, which is an important aspect in

underground mining.

To ensure optimum yield and effi ciency from your mine under all conditions, Voith

TurboBelt TT Linear Booster Drives deliver the benefi ts that mean the most: ease of

use, fl exible operation, easy maintenance, enhanced productivity and extended belt life.

With Voith TurboBelt TT Linear Booster Drives, you get improvements at every stage.

Increase conveying capacity and extend belt service life.Voith TurboBelt TT Linear Booster Drives are also used to

increase the performance of existing belt conveyors.

When it becomes necessary to expand conveying capacity for

operational reasons, a performance improvement is required.

This means either increasing belt quality (i.e. a new belt) and/

or strengthening the drive station in conventional plants. By

implementing TT drives, this problem can be economically

solved. The existing drives and belt remain unchanged, while

TT drives can be assembled and deployed quickly for reduced

downtime. This solution avoids the need for intermediate

transfer points, resulting in reduced stress and less dust.

How the TT Linear Booster Drive works.The TT Linear Booster Drive is equipped with a head and tail

station, which is integrated into the actual belt. The drive is

assembled directly within the current conveyor system. The

top belt of the existing conveyor system (carrying belt) rests

upon the top belt of the introduced TT drive (pushing belt).

The TT drive leads the tensile force linearly through a friction

lock in the belt. Belt tensile forces are signifi cantly lower than

with standard solutions.

Engineering.Voith Engineering teams design and develop optimized

solutions for every belt conveyor system. Depending on your

operation, these can include TT Linear Booster Drives, as well

as  tripper drives and conventional  confi gurations. We also

provide complete project management  services and super-

vision of on-site construction and testing.

Voith TurboBelt Hese Pulleys.Voith offers belt conveyor pulleys engineered for your specifi c requirements and applications, including drive pulleys, tail pulleys, bend pulleys and more. Our technical team designs and engineers pulleys based on the environmental conditions for each application area. They can be up to 3 000 mm in diameter, 6000 mm in length, and built to handle loads greater than 4000 kN. Each pulley delivers excellent running charac-teristics under extreme conditions, such as heat, cold, and humidity. Our pulleys are also built to last, with a product lifetime of up to 10 years.

Pulleys play a key role in ensuring conveyor system effi ciency. To avoid failures that can lead to prolonged downtimes and loss of production, we offer highly effi cient engineered pulleys designed to your specifi cations for maximum reliability and performance. For high-stress applications, fi nite element method (FEM) calculations are performed in the design stage. In manufacturing, high-quality parts and materials — as well as a special T-bottom design that places welds away from high stress zones — ensure a long and reliable service life.

The Voith TurboBelt Transfer Station is used for bulk material

transfer in conveying systems, allowing for smoothly sliding

transfer onto the discharge belt. This provides various bene-

fi ts: reduced wear and tear on the belt; less dust production,

and preserving the grain of the conveyed goods.

In order to adjust belt conveyors in alignment with progress in

the mining longwall, conveyor belts either have to be short-

ened or lengthened. To enable this, a Voith TurboBelt Storage

Loop can be integrated into the belt conveyor system. Voith

Storage Loops can hold approximately 250 m of belt, thus 

minimizing belt connections. Voith also offers a wide range of

tension station designs for above-ground and underground

operation.

Voith offers a wide range of belt conveyor couplings from 37 kW

to 4000 kW. Voith couplings actively protect the motor and belt,

which are the most important (and expensive) system compo-

nents, while providing effi cient drive power transmission and

reliable operation. They automatically adjust applied torque to

suit load conditions, and in multi-motor drives they provide

automatic load sharing. Voith fl uid couplings are ideally suited

for use in our TurboBelt TT Linear Booster Drives.

Voith’s engineering experience and know-how are second to

none in the mining industry. Based on our extensive knowl-

edge and technical expertise, we can also design and engi-

neer complete drive solutions for belt conveyor drives. Our

drive packages include motor, gearbox, connecting coupling,

base frame and a control unit. Based on your specifi c require-

ments, we can determine the most appropriate drive system

for your operation.
