Advantagesforlongtravelapplications
with igus® e-chains®
● Travels over 1,000m
● 6m/s speed (up 10m/s possible after
consultation with igus®)
● Fill weights 70kg/m
● Service life years and more with igus®
e-chain systems®
● Morethan20yearsofcontinuousimprovement
of the igus® rol e-chains® for long travels and
reduced drive force
Further advantages compared to
alternative technologies
● Many different types cables and hoses can
operatetogetherinthesamesystem(i. will always offer the most
cost-effective solution, taking the technical requirements and operating safety into consideration. The diagram below shows this.
