igus® offers the right solutions in the field of energy supply and energy guidance systems for both rotary cranes and port cranes on ships and offshore systems.
The E4-1 series energy chain or the heavy-duty roller series are used on gantry chains (also known as riser gantry cranes), which are beneficial mainly due to the corrosion-free operation and a cable-friendly interior separation compared to festoon systems or steel energy chain. The plastic inner and outer surfaces and the small support spacing result in a very cable-friendly friction pair between the energy chain and the cable, which is reflected in a significantly increased service life of the cables and the system compared to the steel energy chain and festoon. In addition, igus® provides the offshore and shipbuilding market with appropriate maintenance-free complete systems consisting of an energy chain, chainflex® cables and trough systems to provide ready-to-connect complete systems that are easy to integrate. Custom designs, especially according to customer requirements, can also be planned and implemented by the igus® engineering team.
For rotary cranes, rotary modules (RBR) can be used instead of the usual slip rings. These can be particularly beneficial in terms of the maintenance-free property and modularity compared to slip rings or festoon systems. In case of a rotary module, the service life of the cables is significantly increased by the use of a cable-friendly energy chain in combination with a well-designed trough system. This reduces downtime and maintenance intervals of the entire system by up to 90% compared to festoon systems and slip rings.
In addition, media such as hydraulic fluids or water, as well as glass fiber cables can be integrated into the system, which has a distinct advantage over the slip rings and festoon systems. Delivery times are significantly reduced and time is saved during planning thanks to a large selection of standardized rotary modules, . The igus® engineering team is also able to respond to special customer requirements by providing ready-to-connect complete systems with the focus on simple integration into the customer structure and a maintenance-free and long-lasting system.
