E4/4 system, circular motion

E4/4 cable carrier mounted around the side of a port crane

The E4/4 cable carrier system is applied in two areas: For extremely long travel distances and for unsupported, side-mounted application. The famous "tongue and groove" design 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 cable carriers real specialists for long travel distances.
