Energy supply solutions and chainflex® cables for bridge cranes

In the area of crane systems, safe and fault-free cable guidance is extremely important for functional safety. As demands on travel distances, speeds, accelerations and precision are steadily increasing, the energy supply system and the cables must be able to withstand ever increasing loads. Installation, operation and maintenance should require a minimum of time and anticipated downtime. "Off-the-peg solutions" for indoor cranes and bridge cranes are rarely an option. Especially in the international market with its different conditions and standards, crane manufacturers and end users require multifunctional machines and variable components that can be easily adapted to the respective situation. All these requirements are met by igus with its versatile and extremely durable energy supply systems.

Advantages of igus® solutions:

  • Cost-effective
  • Saves installation space and weight
  • Maintenance-free for 24/7 use
  • Fast delivery
  • Easy assembly
  • Complete system or individual components from batch size 1
  • Service life calculation
  • Low noise and low vibration

White paper cranes in steel plants  

White paper: efficient energy supply systems for cranes in steel plants

Modern steel production takes place in steel plants with increasingly high levels of integration. What technical challenges result from this for the transport and conveyor plant used, especially for the cranes in steel plants? How can an energy supply be achieved that is both reliable and efficient? There are two options: festoons and energy chains. What system has more advantages?

Easy and quick to install

guidefast assembly The guidefast guide trough is ideal for moving motor cables on the crane. In the trough, an energy chain with the cables travels from A to B, thus ensuring a long service life, even with continuous load and the smallest bend radii.The guidefast can be installed on the crane in four simple steps:

  • Attach bracket
  • Connect the guide trough and screw on
  • Insert energy chain with cable and fasten
  • Connect trough joints with the help of clips


The guidefast control assembly The guidefast control cable guidance for crane control pendants is installed in a flash. The cables of the control pendant are guided in an energy chain, which maximises their life and minimises cable tangling.The guidefast control can be mounted on the crane in five simple steps:

  • Attach bracket
  • Connect guidefast guide troughs and screw on
  • Insert energy chain with cable and fasten
  • Insert guide carriage and connect with energy chain
  • Attach end stopper


Tested for real-world applications in the industry's largest test laboratory

Take a peek into the chainflex and e-chains test laboratoryHave a look at our test laboratory for chainflex cables and e-chains, where tests are run for 10 billion cycles every year.


Long travels in field testIn the case of long travels, e-chains are subjected to field testing with the help of sensors.

Process crane with igus rolling energy supply

In their hot rolling mill, Thyssen Krupp uses a slab transport crane from BANG Kransysteme GmbH & Co. KG, which is equipped with rolling energy supply systems from igus. The use with constant movement, small installation space, high temperatures and high dirt is no problem for the energy supply systems from igus. Temperatures around 70°C are reached even under the roof. No problem for the chainflex cables used. They are all equipped with a TPE jacket that can withstand high temperatures.

Rolling energy supply in bridge crane

Harnessed energy supply systems for customer-specific indoor cranes

In many indoor cranes, the energy supply is implemented by means of loosely suspended festoonings that travel with the crane. By using igus energy chains, the required installation space can be reduced many times over, for example, to an installation space of 300 x 500 mm. By safely guiding the chain in a trough, the risk of failure of the entire system is also minimised.

Extremely space-saving energy supply

The e-spool® energy guide is a modular system. In this application, it could therefore be adapted individually to the requirements. Advantages for the user in this case were that the e-spool® energy supply is very space-saving, since the energy supply systems are right on the crane.

e-spool in bridge crane

Safe cable guidance in waste incineration plant

In this waste incineration plant, the cables on the bridge crane are guided by igus' long-lasting e-chains. Since the e-chains are very tough, they are not easily intimidated by the harsh and dirty environmental conditions.
