Troughed belt conveyors with horizontal curves were brought to industrial use by BEUMER. Because of their curved routing and minimum curve radii, these systems offer a low-cost alternative to systems, made of straight-line units with transfer points. By transporting material simultaneously in both directions utilizing the top and bottom belt strand, it permits the customer to operate the system in an even more economical way.
With this technology BEUMER has set new milestones.

Transport devices are intended for continuous transport of overburden, coal or extracted rock in open-pit mine conditions.
The basic transport devices manufactured by UNEX Inc. are conveyors with rubber belts stiffened with textile or steel-cord meshwork. Belt width ranges from 1 200 to 2 250 mm and their max. transport capacity is up to 10 000 m3/h. Depending on the mining technology conveyors can be design in two versions: movable or immovable.
Driving and return stations can move on rails (in axis or fanlike fashion) using rails or caterpillar undercarriages (rigid or load sensitive).
For extreme conditions (contact pressure of lower than 0,07 Mpa) the driving and return station can be design by means of hydraulic walking undercarriages.
Adjusting and adapting every individual conveyor in accordance with customer requirements and technological conditions is a matter of course.
All parameters of transport devices are in-tune with a series of UNEX bucket wheel excavators. Together with additional equipment for loading, directing and deflecting material flow they form complete technological complexes. The conveyors are able to work in fully or semi-automatic mode. Maintenance costs are minimal.

Belt conveyors of the LEGMET are dedicated for underground mining of ores and should be installed in haulage routes incorporating high-capacity conveyors. The LEGMET conveyors can be also used in other industrial sectors whenever haulage equipment with adequate parameters is desired.
Design of the LEGMET conveyors makes it possible to use the equipment for heavy-duty and very specific applications. The conveyors are widely operated in copper ore mines of the KGHM Polska Miedź S.A. (KGHM Polish Copper plc.)
The LEGMET conveyors use belts of 1000 - 1200 mm width. They can be applied to material haulage with rates up to 1000 - 2000 t/h in underground workings with incline angle up to +15° and decline angle to -5°.

Belt Conveyor Systems continuously transport bulk materials, excavated and crushed rock material in a clean and efficient manner over long distances, through curves and up and down via considerable inclinations. The design parameters strongly determined the climatic conditions and material properties.
Tenova TAKRAF Belt Conveyors can be stationary, shift able, enclosed, running in tunnels over long distances, mounted on sleepers, on rails and onto the tunnel roof. The belt width ranges from 1 m to 3 m, the maximum belt speed today reaches 6,1 m/s in copper mines (even 10 m/s on conveyor bridges).
Besides countless belt conveyors in lignite mines worldwide, in 2000 Tenova TAKRAF built a conveyor system with the world longest 16.8 km single conveyor , thereof 16 km inside of an inclined tunnel. Milestones in the development of conveyor systems are installed downhill overland conveyor of El Abra and the in pit and ex pit conveyors of the Escondida mine in Chile.

Tenova TAKRAF has been building conveyor bridges since 1924.The mobile conveyor bridges in the German Lignite mines transport the material from the excavators directly crossing the open pit onto the dump site. Special operational conditions there allow capacities up to 29.000 m³/h from three Bucket Chain Excavators, a span length (distance between the supports) of 270 m and a dumping height of 74 m. The 13400 t Conveyor Bridge travels on rails. One support stands on the excavation site, the other one on the dumping side. The extraction of the lignite takes place between the supports.
Another application of Tenova TAKRAF conveyor bridges are Dumping the Heap Leach Systems. These conveyor bridges are also fully mobile and transfer the material from reclaimers, overland conveyors or connecting conveyors to the downstream conveyors, Mobile Transfer Conveyors or Stackers (Spreaders) as seen in Gaby/Chile or Toquepala/Peru.

Tenova TAKRAF developed and supplied Slope Conveyor Bridges as a mobile link between a Bucket Wheel/Chain Excavator and a shiftable conveyor installed on a bench with a higher level. The advantages of Slope Conveyor Bridges are on the one hand the location of the face conveyor already on the next higher level and on the other hand the elimination of a ramp conveyor. The slope will be bridged by the Conveyor Bridge without any earth work.
Tenova TAKRAF's Slope Conveyor Bridges in Kazakhstan have a capacity of 5500 m³/h and can handle height differences up to 28 m.

dhms can supply mobile chain scraper conveyor systems, both with and without crushers, for transferring drivage debris to outbye rubber-belt conveyors.
The integral pusher system with its attached belt return end and table feeder for the conveyed material allows the conveyor installation to be advanced quickly and with minimum
outlay in roadway and tunnel drivages. A range of different designs can be supplied to suit specific operating requirements.
The facility to advance continuous conveyors and crushers quickly and reliably is essential for achieving high performance rates in highly mechanised roadway drivages. This system does away with the manual work of setting up and anchoring the belt conveyor return end. Conveyor advance and alignment, height adjustment on the crusher drum and conveyor chain tensioning are all achieved by hydraulic power.

Mobile Transfer Conveyors (MTC) are "multi use" equipment in open pits. Determined by operational requirements, the design can be distinguished in fully mobile and semi mobile, self driven or not, one or two single conveyors, lifting, luffing and slewing of no, one or both conveyors.
Mobile Transfer Conveyors are installed between Bucket Wheel/Chain Excavators and the shiftable bench conveyor allowing multi block and multi bench operations to increase the block width and the block height. Thus, increasing the time between two shifting operations of the bench conveyor - results in a higher utilization of the mining system. Mobile Transfer Conveyors are used also as a combination of transfer conveyor to the bench conveyor and direct dumping onto the pit floor in coal seems with interburden layers. Grasshopper style Mobile Transfer Conveyors installed as a chain like one connected to the other are part of waste dumping and Heap Leach Systems.
Tenova TAKRAF offers Mobile Transfer Conveyors of all types in a wide range of capacity and lengths up to 95 m.

The line of IMER Group belt conveyors stands out for the versatility of its applications in the work yard. Our range is made up of LT 1200, LT1500 telescopic and LT1600 telescopic.
The belt conveyors are driven by a hydraulic transmission in vertical position capable of turning 280° around their axis, facilitating their positioning and manoeuvrability, even on uneven ground. During the distribution, the truck must remain parked in the area where it is positioned.
The speed of the conveyor is independent of the vehicle that carries the mixer or of the auxiliary motor, as it is provided by a hydraulic fixed displacement motor connected to the conveyor drive roller, which in turn is driven by a hydraulic pump connected to the power takeoff of the vehicle transmission.
The conveyor structure is made of steel with a high yield point providing the necessary sturdiness and elasticity. The accurate design and the constant attention to the requirements of the end user gives the belt conveyors reliability, and allows easy access to all their parts for cleaning and maintenance.
The conveyor makes it possible to easily and immediately distribute, at the desired point, the material contained in the mixer: concrete, gravel, sand, cement-bound granular material, etc.
The conveyor is ideal in the building of foundations, small floors, and also concrete pillars and road works. It is an ideal means, both in functional terms (flexibility and versatility, even in severe conditions) and in economic terms.
