Energy chain in open-air storage facility for alumina production
Design and installation of a roller energy chain for outdoor use on a bauxite stockpile - an environment with extremely harsh ambient conditions.
E4/4 system applications
The E4/4 system is applied in two areas: For extremely long travel distances and for unsupported, side-mounted application. The famous "tongue and groove" between two chain links enables this feature. Compression forces and stability are enhanced, whereby the power of resistance against wet and rough weathering is increased. Special roller chain links make E4/4 real specialists for long travels. The undercut design - the simple mounting in specified grooves similarly enables the outstanding ESD/ATEX performance. The chain links are tightly linked to each other, because electricity can flow through them when in contact with each other (Please note: This is valid only for the special conductive material igumid ESD and is not applicable for the standard series in this catalog).
Typical industrial sectors and applications:
RTG, quayside cranes, many other types of cranes, composting plants, plaster, concrete, chemical and mineral plants, as well as agricultural plants, machine tools: Unsupported, side-mounted applications in construction machines, ESD applications, heavy machinery, steel works, shipyards, welding plants.
Overview of E4/4 applications:
Astronomical telescope
This telescope can be rotated from its original position in both directions by 270° each.
Coal silo
Lower weight and space requirements than alternative solutions for conveying coal.
Collision Avoidance
System]
These applications test systems that will make driving cars safer.

Coal transport system
The motors in this system need a large number of cables.
Reversible-head trimming shears
Quick tool changes permit continuous machining of metal bands on both sides.
Material treatment
This application prepares raw material for the subsequent production of screws and rivets.
Zinc electrolysis, bathing halls
The sulfur fumes generated by the electrolysis are highly corrosive and corrode the customer's system. igus® products withstand these extreme conditions.
Rocket launch site
The igus® products used are designed for mobile applications in such a way that it features a long life and functions absolutely reliably.
Sand blasting machine
Sandblasting machine for treating the surface of wind power tower sections.
The longest travel with plastic energy chain
The complete length of the E-Chain®'s travel at 615m clearly exceeds the previous record holder at the Singapore harbor.
Discharging station for crude metal/metal scrap
Almost maintenance-free solution in a discharge station for crude metal/metal scrap, thanks to the energy supply system with plastic products from igus®.
Composting plant
Heat, abrasive dirt, high atmospheric moisture: These are only some of the ambient conditions in a composting plant.
Ship unloader
441m travel with E-ChainSystem® in Malaysia: Reduction of tensile strengths by about 75%, E-Chains® with weight up to 2.5 tons.
Streetcar switches
The applied material repels chips with temperatures up to 850° C without leaving a trace.
Ship loader
Since the ship loader started operations in 2000, no troubles, either mechanical or in the cables, have occurred in the energy chain area.
Automotive industry
Gliding, side-mounted application in the automotive industry.
Space-saving solution
Zigzag solutions implemented quickly and economically without special parts with the E-Chains® of the E4/4 system
Unsupported application
Stability guaranteed even in air: Unsupported "side-mounted" application.
Standing installation
High accelerations also possible in "standing" installation.
Wood industry
The igus® preassembled energy chains create a lasting, low-wear connection to the tools.
Fairground rides
The demands on the facility are very high. All parts of the elevator are permanently exposed to wind and weather, and additional centrifugal forces act upon the parts by the 180° rotation.
Lignite quarrying
The wagon makes a 180° turn and empties into the coal bunker. The energy chain secures the energy supply of the rotating device.
Offshore industry
Tube handling plant provides an igus® plastic E-Chain®. E-Chain® ensures high stability and reliability in pipehandling.
Loading and unloading facility
The demands on the energy supply systems are very high: High cycle times and narrow bending radii significantly strain the energy supply system and cables.
Chrysalis
For the equipment made for the film "Chrysalis", only high quality materials were used.
OpenHydro tidal turbine
A plastic chain makes any kind of maintenance on the open sea obsolete; a conventional metal chain would not be adequate for the combination of technical, climatic and mechanical requirements.
Handling system ”roboLoop“
The ”roboLoop“ system itself offers manyways to optimise the fabrication sequences.
Adhesive resin system
In the case of this adhesive resin system, a lifting platform moves upwardto a height three or four times a day to empty barrels with a volume ofapprox. 200 litres.
Spray-painting robot
In this application in a painting robot, the ATEX properties of the energy supply system are of primary importance.
Pallet changer
In the case of this application, the worksafety was increased by integrating theenergy supply system into the body of thepallet changer.
Palletising system
This energy chain® in the palletising system of a dairy is subject toextreme load with more than 5,000 strokes a day.
Piling and drilling rigs
The driven boring machine produces extremevibrations and heavy soiling duringthe work process.
Tunnel boring machine
This machine moves deeply through the earthand is used to drill tunnels using the excavationby mining technique.
Dismantling tool
During the removal of a nuclear power plant, 14 metre-high steel tanks are milled into small metal chips. At the same time, a milling cutter, which is used as a dismantling tool, must be inserted precisely into the tank from above.
Maintenance-free operation for 8 years
The energy chain employed in 2000 runs smoothly.
Plastic E-Chains® replace steel versions
After six months they used to be finished; finally no more failure thanks to plastic E-Chains®.
Indoor and outdoor cranes
Outdoor cranes must withstand severe weather conditions. Even indoor cranes work under ever-changing humidity conditions together with very high temperatures.
Shipyard
Eight gantry cranes connected in series travel a total length of 180 m with plastic Energy Chains®.
Hydraulic lifter in airplane hangar
Hydraulic working platforms in an airplane hangar for the Airbus A380 in Singapore are equipped with igus® E-Chains®.
Conveyor unit of coal excavator
The winner of this year’s golden vector® is also the longest travel ever to be realised with plastic Energy Chains® in the world.
Crane applications
In this case, two different crane applications have been realised using the igus® Energy Chain® series 5050 from the E4/4 range
Wind tunnel scales
These scales which are used for tests in the wind tunnel can be turned through 180° in both directions away from their original position.
