Indoor crane system examples

View all successful applications in the crane industry

Slab handling crane

Heat and dust: energy chains for adverse conditions

In Thyssen Krupp's Duisburg hot rolling mill, a slab transport crane from BANG Kransysteme GmbH & Co. KG is responsible for handling the slabs at the interface between the steelworks and the rolling mill - in heat and dust. The supply of energy and signals to the trolley and cab is ensured by heavy-duty igus energy chains supplied pre-assembled as basic readychain systems.

Crane in cement plant

Crane in cement plant

With this crane system for storing and removing sewage sludge in a cement plant, an energy chain has proven itself through flexibility, variability and space-saving installation.

Chemical-resistant indoor crane

Chemical-resistant indoor crane

Plastic energy chain systems for supplying energy to process cranes have proven themselves for several years in this hot-dip galvanizing plant under high acid loads.

Indoor crane in metal processing

Indoor crane in metal processing

In this indoor crane application, our e-chains show their advantages: even under the heavy load of dust and hot metal swarf, there has been no failure in three years.

Bridge crane in steelworks

Overhead Bridge crane in steelworks

This crane transports billets in a steel mill using a magnetic beam. For the power supply of the slewing gear, the developers are using a triflex series e-chain instead of the previous conductor rail.

Gantry cranes in concrete plant

Overhead Gantry crane in concrete plant

In the harsh environment of concrete processing, energy supply systems contribute to the stability and reliable function of indoor cranes.

70m crane track in waste incineration plant

70m crane track in waste incineration plant

In the Eschweiler waste incineration plant, the existing trailing cables were replaced by an energy chain that was developed for use under adverse environmental conditions.

Indoor crane: 50% more storage space

Indoor crane: 50% more storage space

This indoor crane had an extremely low clearance height. Our pre-assembled energy chain solution created 50% more storage space.

Indoor cranes in the foundry

Indoor cranes in the foundry

Containers containing liquid metal are transported in a foundry using these three cranes. The hot environment and high levels of contamination placed severe demands on the cable guidance.

Coil crane in steelworks

Coil crane in steelworks

In this coil crane, the motor-driven cable drums required a high level of maintenance. That is why they were replaced by our e-spool system.

gantry crane

guidefast system for gantry crane

The manufacturer Piedmont Hoist and Crane in the USA opted for the convenient guidefast modular guide trough system for a gantry crane.
