Energy chains for double-girder travelling cranes

In contrast to single-girder travelling cranes, double-girder travelling cranes or double-girder gantry cranes are designed for significantly higher lifting loads. The cranes usually bridge large hall areas and therefore often require rapid movement of the goods to be transported.
This requires robust energy chains, guide troughs and cables for high travel speeds and accelerations, which can also be easily retrofitted into existing crane systems and allow quiet movement.

e-spool energy chain - The alternative to a cable drum without slip ring
e-spool combines two different energy supply systems in a unique way: A standard energy chain is guided by a roller, providing the correct length and tension of the energy supply system through an integrated retaining spring. In the home position, the energy chain is completely rolled up to save space. The twisterband connects the roller with the shaft end block, serving as an interface to the permanently installed cables.

Liftband energy chain - vertical applications up to 13m
liftband - modular, quiet, space-saving - vertical guidance of energy, data and media. With the liftband, high vertical applications can be implemented, which have a lot of space available horizontally but only allow for low system heights.

e-drum energy chain
A modular system allows flexible adaptation to the application in question. The slip ring-free modular system of the e-drum allows the user to create a compact and durable guidance and drum-reeling system for energy, data, air and liquids.

Heat and dust: Energy supply under 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-fitted as basic readychain systems.

50% more storage space thanks to pre-fitted energy supply systems

Kranservice Herz mainly designs bridge and gantry cranes up to a load capacity of 100t and spans of up to 40m. For a new project – an automatic crane system for loading stainless steel pipes – special environmental conditions were met. Due to the structural conditions on site, the operator required an extremely low clearance height. The solution consisted of pre-fitted energy chains that save 50% storage space.

Robust energy chains for harsh environmental conditions in foundries

These three cranes are used to transport containers of molten metal in a foundry. Each crane has a lifting capacity of 100 tonnes. A hot environment coupled with extremely high levels of contamination on the crane from moulding sand, graphite and metallic dust is the challenge here for the energy supply system. By using our E4/4 series roller e-chains, it was possible to achieve permanently trouble-free operation in the harsh environment.

Manufacturer relies on guidefast system for easy installation of e-chains

The manufacturer Piedmont Hoist and Crane in the USA opted for the convenient guidefast modular system, which is now standard in the "double-girder crane systems" segment: The guide trough for attaching the energy chain to the side of the crane girder impresses with its quick and simple installation. And the design is also an additional aspect for users.
