Reclaimers / bucket wheel excavators

e-chain systems® as an alternative to slip rings, cable reels and festoon systems

The systems often used traditionally for transmitting energy can both be replaced by e-chain systems® on new equipment and for retrofit on existing stackers and reclaimers Here the advantages are:

Simultaneous transmission of different media
Continuous connection of fibre optic cables or wire-bound data connections
Minimum maintenance
shorter cable lengths
less space required (no loop stations)
Resistance to weathering effects

Hereby, our igus® engineers and technicians are happy to help you with the analysis of your application.

Rotating energy supply in stackers and reclaimers

igus® rotating energy supplies achieve a wide range of circular movements. Rotation angles of up to 900° have been achieved. Below you can find an example of such a circular movement with a rotating energy supply. Please consult us for your particular application.

Circular movements require less installation height. The e-chains® slide mostly on surfaces made of plastic, stainless steel or steel and are guided through baffle plates in the circular movement. See side mounted for further design tips. Bend radii, circular radii and e-chain® widths are variable with this product range.
