E4/4 system applications

The E4/4 system is applied in two areas: For extremely long travel distances and for unsupported, side-mounted application. The famous "tongue and groove" between two chain links enables this feature. Compression forces and stability are enhanced, whereby the power of resistance against wet and rough weathering is increased. Special roller chain links make E4/4 real specialists for long travels. The undercut design - the simple mounting in specified grooves similarly enables the outstanding ESD/ATEX performance. The chain links are tightly linked to each other, because electricity can flow through them when in contact with each other (Please note: This is valid only for the special conductive material igumid ESD and is not applicable for the standard series in this catalog).

Typical industrial sectors and applications:

RTG, quayside cranes, many other types of cranes, composting plants, plaster, concrete, chemical and mineral plants, as well as agricultural plants, machine tools: Unsupported, side-mounted applications in construction machines, ESD applications, heavy machinery, steel works, shipyards, welding plants.
