Bucket Wheel Excavator & Stacker-Reclaimer Cable Management Solutions

e-chain® cable carrier systems are an alternative to slip rings, cable reels & festoon systems

The classic cable management systems that have been frequently used for supplying energy within bucket wheel excavators and stacker-reclaimers can be easily replaced and retrofitted with long-lasting e-chain® cable carrier systems from igus. e-chain® cable carriers have long and predictable service life, and can be installed effieciently by our expert team of engineers.

Benefits include:

Concurrent transmission of various media
Continuous connection of fiber-optic cables or wire-based data links
Minimized maintenance effort
Shorter cable runs
Low space requirements (no cable junction)
Resistance to weather influences

Circular movement with "RBR"

"RBR" means reverse bending radius, which means that the e-chain® can bend in two directions. Configurations with "RBR" can be fabricated for many igus® e-chains®. The "RBR" is not necessarily identical with the "BR" (bending radius) of an e-chain®.

Most rotary motions can be achieved with the RBR option. Angles of rotation up to 900° have been realized. Below is an example of rotary motion using an RBR e-chain®. Please consult igus® for your particular application.

Circular motions require less installation height. The e-chains® generally glide on surfaces made from plastics, stainless steel or steel, and are guided into a circular motion by guide channels. See "side mounted" for further design tips. Bending radii, circle radii, and chain widths are variable in this product range.
