High stability, low wear, and a maintenance-free roller system to reduce push/pull forces
... travels greater than 800 m possible
... low wear
... low elongation of the entire system
"In comparison to the standard E4/4, the pin strength is increased by up to 40%. “
Large pin/hole connections with tight tolerance provide a high push and/or pull force absorption potential. Due to the tight tolerances and the resulting, almost complete zero backlash, very high accelerations can be achieved and there is very little wear.
We test every energy supply system with a "tweak testing machine" at the igus® laboratory for compressive/breaking strength to provide reliable specifications on max. additional load and unsupported length
Test 3992:More than 30.000 N tensile strength
The longest plastic distance in the world covered by an igus® e-chain® was designed and delivered for the largest power supplier in the Czech Republic, the CEZ Group. The distance covered is 615 m.
The stable pin/hole connection enables such long travels thanks to high push/pull force absorption.
... maintenance-free rollers reduce push/pull forces by up to 75%
... increased additional loads on long travels
... reduction of the required drive power
The integrated rollers allow the chain to roll on itself instead of gliding.
Various tests in the igus® lab demonstrate the higher load on the E4/4 HD roller chain.
igus® roller chains particularly demonstrate their strengths and reliability on cranes in heavy-duty applications.
… no restrictions with respect to dirt loads
… high additional loads
… heat, moisture, and cold … no problem.
Reinforced pin/bore connections, wide glide surfaces, high torsion stability - these are the primary characteristics of our heavy-duty systems.

… high stability and rigidity
More than two stop dogs cannot be, or can barely be synchronized. Due to a rectangular shape, the force distribution is much better than in a round stop dog (surface pressure formula, p = F/A).
Downtime is expensive - energy chains with high stability and reliable, long service life are therefore mandatory for crane plants of all types.
up to 9 mm wider glide surfaces in comparison to the standard System E4/4
Wider glide surfaces + wear allowance
Tested and proven in the igus® lab under real-world conditions.
Reliably solve long travels with igus® e-chains®, like the E4 series here in a gantry crane, guided in an igus® guide trough for 220 m.
... speeds on long travels, even in heavy-duty applications.
Guide troughs with riser guard - the correct height for the moving end and integrated rollers facilitate high speeds even on long travels.
Special features, such as a riser guard or the correct height of the moving end were developed and tested by the igus® lab.
Container cranes can load and unload ships with speeds up to 4m/s. This is easily accomplished with igus® roller chains.
... nearly halve the cable wear
... less parts, more possibilities
Smooth, cable-friendly and rounded contour provides for a long service life of the cables and hoses. In addition, a better and more cable-friendly interior separation can now be implemented with less standardized components.
With the new rounded separators, the wear of the cables could be almost halved.
Test 3748:Separator 301 compared to new version 45.1 The matching pair of plastic and jacket material also turns out to be the best here.
In this case, the rounded plastic opening crossbars help to extend the cable service life.
… "infinite" width extension with extension links
… shorten and extend directly on location.
Due to the modularity of the igus® construction kit system, our System E4/4RHD can also be extended in length/width and shortened on demand. The igus® extension link system has no width limitation.
Lab test with a E4/4 extension link chain
High filling capacity in outdoor environment. These are the typical features for igus® E4/4RHD extension link chains.
... reliable data and power transfers in an e-chain®
... dynamic hydraulics guided reliably.
… the world's only energy supply system that can reliably guide all media at the same time.
In addition to cables, the system can also guide hoses, bus cables, fibre-optic cables, etc. This is unique in the industry.
All cables and hoses we offer were tested by igus®.

... extended running performance guaranteed at low maintenance
... for long travels in outdoor environments.
"Up to 9 mm reinforced side plates when compared to the standard E4/4"
Reinforced side plates nevertheless allow loads from push/pull forces
Every e-chain® achieves at least <10,000 km running performance on long travel Reinforced side plates facilitate this even at high loads.
In this environment, igus® RHD chains already realistically achieved a running performance of 70,000 km.
... convenient replacement of cables
... good accessibility in all positions
Crossbars can be opened with the igus® screwdriver. The e-chain® is then conveniently filled from both sides.
Countless installation kits in our lab prove the easy and convenient filling of e-chains®.
Even under the most difficult conditions, the e-chain® can be opened and closed with ease from all sides.
... maintenance-free, pre-lubricated and encapsulated stainless steel ball bearings for any environment
... various roller types for various applications.
Lubricated once, and then sealed. The rollers on igus® roller chains are completely maintenance-free.
Various materials were tested in our lab. Ultimately, igus® is in a position to supply the correct roller for any application.
Even fine dust will not negatively affect the encapsulated stainless steel bearings in igus® roller chains.
... reduced push/pull forces
… rolling instead of gliding.
The integrated rollers facilitate travels of up to 800 m.
All systems are tested in our lab under real-world conditions. For instance, we are testing for crane plants on more than 100 travels.

... high additional loads for unsupported and gliding operation.
... ideal for high torsion forces
The chain links are "hooked into one another", which provides for extremely high torsional stability of the e-chain® and for high unsupported lengths even in side-mounted applications.
Here we also test every system for maximum load capacity to get reliable information on service life, which is also incorporated into our online service life predictor.

... igumid® ESD corresponds to classification Ex II 2GF
... conductive in unsupported and gliding operation
igus® achieves conductive properties thanks to the igumid ESD material.
100% of the produced ESD e-chains® are tested for their electrical continuity.
To meet the high demands in offshore applications, our chains are tested in terms of both load capacity and conductivity.
