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:

Plastic energy chain for high levels of hydrochloric acid in indoor cranes

An energy chain and plastic trough made of chemical-resistant plastic have been used successfully in this hot galvanising plant for years.

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.

X-ray device

This flexible system can take x-ray images without moving the patient.

Helicopters

Lighter components for aviation applications by avoiding separators.

Rocket launch site

The igus products used are designed for moving applications in such a way that they have a long service life and are absolutely reliable.

Plastic energy chain on 550-metre travel in bulk handling

Under extreme conditions such as heavy dust and dirt, this low-maintenance plastic energy chain ensures safe operation.

Energy chain for stackers on 615m travel without failure for 10 years

A plastic energy chain travels 615m in length in the Czech lignite-fired power plant in Tušimice. It has been in operation for 10 years without any downtime.

Lubrication-free plastic energy chain operates fail-safe in steel mill

In this steel mill, a metal chain was replaced by a plastic energy chain that has been fail-safe since 2007, together with chainflex cables designed for moving applications.

Composting plant

Heat, abrasive dirt, high atmospheric moisture: These are only some of the ambient conditions in a composting plant.

Roller energy chain on ship unloaders over 400m travel

On a 441.3 m travel, a roller energy chain reduces the drive power by 75%

Streetcar switches

The applied material repels chips with temperatures up to 850° C without leaving a trace.

Energy chain at the bulk goods ship loader in the Baltic Sea port of Wismar

Since the ship loader started operations in 2000, no troubles, either mechanical or in the cables, have occurred in the energy chain area.

Wood industry

The igus® preassembled energy chains create a lasting, low-wear connection to the tools.

Completely pre-assembled energy supply for gondola lift in fairground ride

Robust, safe, UV-resistant: A pre-assembled energy chain ensures the power supply to the lift at the funfair as well as quick set-up and dismantling.

Offshore industry

Tube handling plant provides an igus® plastic e-chain®. e-chain® ensures high stability and reliability in pipehandling.

Loading and unloading facility

Rigorous requirements imposed on the energy supply: Cycle times and narrow bend radii are a considerable strain on energy supply and lines.

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.

Saw mill

Even sawdust does not constitute any problem for igus® e-chains®.

Tunnel boring machine

This machine moves deeply through the earthand is used to drill tunnels using the excavationby mining technique.

Indoor and outdoor cranes

Outdoor cranes must withstand harsh weather conditions. Indoor cranes also work under alternating moisture influences with simultaneous extremely high temperatures.

Meyer Werft in Papenburg

Eight gantry cranes connected in series travel a total length of 180 m with plastic energy 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.

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.

Further interesting applications from extremely diverse areas can be found here.
