igus® solutions for top drive systems

Dynamic fill weights through factors such as vibrations and environmental influences are major challenges for energy chain systems and service loops on drilling rigs and especially for top drive systems (also called turning power heads). Thereby the "heavy duty" energy chains from igus®, offer many benefits in extreme conditions on a drilling rig compared to steel chains and service loops, are particularly suitable for the energy supply of turning power heads.
The plastic energy chains are valued for their corrosion resistance and low weight of the e-chain® compared to a steel chain. In addition, the structured interior separation offers clear advantages in terms of service life and freedom from maintenance compared to a conventional service loop system. The locking separators, specifically designed for the application, ensure that the crossbars are securely held and dropping of objects are prevented.

Pre-assembled energy chain systems (readychain® systems) with igus® chainflex® cables offer ready-to-connect solutions and save time in installation and commissioning of drilling rigs and top drive systems on site. The chainflex® cables are specifically designed for use in energy chains and have a guaranteed service life of up to 10 million double strokes. The igus® engineering team gives support, in the connection of the energy chain systems to the top drive and designs turnkey solutions for a safe and reliable system.

Load and break test of the e-loop

igus performs application-specific tests in the in-house laboratory for a long-lasting energy supply.

Load test of the e-loop
The e-loop was tested under extreme weather conditions and vibrations.
Result: high vibrations, side impacts and bumps do not bother 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 swung from a height of 10m onto a safe.
Result: the test proved the e-loop to be resistant to shocks and shatterproof.
