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.

-The RC Conveyor concrete spreader are used in bridge paving and flat slab paving. It can spread in a width from 3 Mts. to 19 Mts.
-The RC Conveyor place concrete in front of the Paver Finisher by Divertar car. Divertar car speed and travel speed are variable and can be controlled from the operator's station
-Conveyor belt unit used alternatively for bed as well as slope position, with minor alteration in the pin connected bolted structure
-High production capability will spread up to 35 CuMt per hour with constant concrete supply and suitable site condition
-Conveyor with standard flange wheel runs on rail, Travel speed of each end is controlled separately. This negotiate the curves easily
-Special charging hopper to permit feeding of concrete by Transit mixer.
-The conveyor can also run bank to bank on smaller canal with suitable shute to place concrete from the canal height.

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.

- Speed of conveyer segment automatically adjustable or
adjustable through the configuration
- Control mode with display of control frequency and
current counter reading
- Control status can be limited using timeout
- Adjustable print control (optional)
(time to monitor the transfer from the previous unit e.g. screen printer)
- Optimal adaptation of the working panel possible (from
length 1000 mm)
- Mounting holes for foot rest and lamp holders are

With KABELSCHLEPP hinged belt conveyors we can solve your disposal tasks in over 80% of all cases:
* Wet or dry chips
* Workpieces and waste
* Hot forgings
* Stampings and punching scrap
* And much more
Transportation of the material takes place on the upper trough of a revolving hinged belt. Drivers ensure transport of the material up the inclined section. For wet machining the cooling lubrications are collected in the conveyor housing and can be fed back into the machine circuit via an optionally available coolant container or a pump station.
Our hinged belt conveyors can be used either as stand-alone conveyors at machine tools, or as linked conveyor systems. Depending on the design, the material to be conveyed is brought to the required height at a defined incline and then discharged.
