Large energy chains for high loads

The E4.1L is a highly dynamic, light and cost-effective energy chain for almost all applications. Due to its high stability and stiffness, it can be used for high loads without problems. In addition, the standard modular system offers a great variety of accessory components. That means that the energy chain can be expanded as required and adapted according to the application.
Typical industries and applications: general mechanical engineering, robot technology and handling, sewage plants, material handling...


Energy chain



Opening and closing completely without tools

  • Inner height: 34 to 82mm
  • 40% less assembly time: crossbar with fastening straps for opening and closing without tools
  • 100% higher pull-out strength: positive-locking crossbar
  • 10% less weight: material recesses for optimised weight and stability
  • 20% more fill weight
  • 17dB(A) quieter



Reduce cost, time and weight

  • Inner heights: 31 to 64 mm
  • Crossbar openable from both sides along inner and outer radius
  • Quiet operation due to integrated brakes
  • Undercut design for the best possible lateral stability
  • Can be closely adapted to the application
  • Best possible value for money 
  • 30% less weight and 80% faster installation than comparable series
  • Double stop-dog system and large pin/bore connection for high level of force absorption


E4.1 series

A series for virtually every application

  • Inner heights: 21 to 350 mm
  • Crossbars removable along the inner and outer radius
  • For especially demanding applications
  • Undercut design for the best possible lateral stability
  • Double stop-dog system and large pin/bore connection for high level of force absorption
  • High push force on long travels and for large unsupported lengths
  • Noise-reducing brake and optional noise dampers
  • Quiet operation due to integrated brakes


E4 light

Large inner heights combined with low own weight

  • Inner heights: 56 to 112 mm
  • Crossbars removable along the inner and outer radius
  • Reduced thickness of the side sections and thinner crossbars

Reliable protection against dirt and swarf


Swarf-repellent chains

Many series are also available as tube or half-tube options!
This will take you to our large selection of swarf-resistant but nevertheless openable e-tubes.
