A new alternative to the service loops on vertical drilling rigs offers longer service life under extreme environmental conditions.
Find out in these installation instructions how to assemble the e-loop® with and without cables.
The interior consists of four injection-molded parts. Two of them form the crossbar in the chain link and are screwed on (captively). Due to being screwed on, they are clamped onto the pull rope,
External protectors made of impact-absorbing PU protector material ensure that the e-chain® and the cables are protected when hard impacts occur.
The individual chain links are clamped onto the high strength pull rope. The rope itself is a plastic-fiber rope and its permissible tensile load is 50kN.
The mounting brackets of the e-loop® are high-strength steel mounting brackets. The plastic-fiber rope, which absorbs the entire tensile force of the e-loop®, is an integral part of the brackets.
Rollers under the e-loop®, for example, for easier movement on the ground. One application example can be the generation of power for ships in ports
e-loop® grip module makes transport/travel of the loop system easier, e.g. on ECI plants, and simplifies the handling in combination with rollers.
Test setup: The e-loop® is dropped from a height of 10 metres onto a vault and hits it with full force.
Result: The e-loop® withstands the collision without problems; its design is resistant to shocks and is shatter-proof.
Test setup: Continuous test of a completely harnessed e-loop® with cable filling for 500t top drive. The test is carried out in the open air with all environmental influences.
Result: The test has run 40,000 double strokes. All influences due to weather do not affect the functionality of the e-loop®. Side impacts, bumps or vibrations do not bother the e-loop®.
We can assist you with a turnkey, fully assembled solutions or answer any questions you may have with a custom project.

A: igus® has developed the e-loop® as an alternative to the service loop so that cables with large cross sections and heavy weights can be guided safely in hanging applications. The energy supply system is a round, three-dimensional modular system that can move strain-relieved cables with a defined bend radius. The cables can be used individually and replaced in case of maintenance. The chain links are also replaceable at any time.
A: The new energy supply system from igus® is built around a high-strength plastic rope that absorbs the tensile forces of the cables. The rope is composed of a synthetic plastic fiber and is therefore shatter-proof, weather-resistant, flexible and corrosion-free.
A: Unhook, lay down, unscrew, exchange cable(s), screw shut, remount. That's all it takes regarding maintenance thanks to the simple modular setup of the e-chain®. For the rarest of cases you should always have a replacement chain at hand to avoid downtime.
A: igus® delivers the e-loop® in the way that you prefer: either completely assembled or fully harnessed, on a drum or on a pallet. There is a defined thread at the end of the e-loop® for additional mounting. Our installation team is happy to take care of the assembly.
A: The individual chain links are all secured with screw connections, so that no component can fall down.
The e-loop® modular e-chain® system is being used in a drilling rig in the oil and gas industry. The igus e-loop® has made it possible to improve the service life of the drilling rig and considerably reduce costs. In addition, the cables in the mast can no longer become tangled.
The e-loop® is used in a bucket wheel excavator made by Holcim (Germany) GmbH. Instead of the planned eight hours of installation time, work with the e-loop® was completed after just four hours.
