For the cable guidance in top drive systems of drilling rigs, manufacturers and operators have so far been using so-called "service loops". However, these often create problems. The cables have no guidance, no defined bend radius, can slip in the service loop and in the worst case, break. In extremely windy conditions, the freely hanging service loop can get caught in the mast or on the sensors as well as the lighting system and be torn off. Replacement of the entire hose package is necessary.
To guide cables securely in hanging applications, igus has developed a new energy chain with the e-loop. As an alternative to the service loop, the e-loop combines the advantages of a polymer energy chain with those of a Dyneema rope that possesses high tensile strength. Ideal for three-dimensional movements. The tensile forces are absorbed by the rope and passed through the mounting brackets into the support structure. As a result, the cables are completely free of strain. The modular e-loop energy chain system made of high-performance plastics ensures a defined bend radius of the cables and withstands vibrations and shocks.
Load test of the e-loop
The e-loop was tested under extreme weather conditions and vibrations.
Results: High vibrations, side impacts and bumps do not impact the e-loop. The modular e-loop energy chain system ensures secure cable guidance on the top drive.
Break test of the e-loop
Test setup: the e-loop was dropped from a height of 10m onto a safe.
Result: The test proved the e-loop to be resistant to shocks and shatterproof.
