series
Push-/pull force in % Zug-/Schubkraft in %
Save 75 % power – Driving force reduction and life time extension
8 Benefits of the Rol E-Chains ® :
1. Strong reduction of the driving force required for moving the Energy Chain ®
to below 25 %
2. Rollers with stainless steel roller bearings as standard
3. Travels up to 800 m possible
4. Possible speeds of up to 600 m/min
5. Different types of rollers for optimum results in different situations
6. Even rolling resistance for dirty applications
7. As ready-to-fit, made-to-specifications system
8. System guarantee for made-to-specifications system (depends on application)
Rol E-Chain ® , rolling, not gliding:
Traditional Energy Chains ® operating over long distances generally “gliding”. Rol
E-Chain ® has been developed with the aim of pushing back the technical limits
of this kind of operation. The demands placed on Energy Chains ® used over
long distances have continuously increased in recent years. Travel over several
hundred meters sets new challenges, as do extreme Crane movement speeds
at cable loads of up to 50 kg/m.
