Storage and retrieval units must also operate reliably in the deep freeze at temperatures down to -30°C. Therefore it is essential that all components, from steel structures up to the energy chain and their cables, are designed and approved accordingly. To ensure a high availability of the system components and to keep maintenance and repair costs to a minimum, particular attention is paid to the plug-in connectors, which reliably ensure power and signal transmission even at very low freezing temperatures.
"As a general contractor, we bear full responsibility for the intralogistics systems of our customers," clarifies Markus Sellen, Product Manager Storage Technology at SSI Schäfer . "For this reason, we only work with suppliers who, on the one hand, take the system concept into account and, on the other hand, understand technical requirements down to the last detail in order to provide the appropriate solutions and further developments. "
The system solution consists of an energy chain of the E2/000 series, fail-safe chainflex control and data cables as well as bus and motor cables. In the deep-freeze area, the ready-to-connect readycable cables are also equipped with Harting plug-in connectors for easy handling. Before the introduction of Exyz, the company did the harnessing themselves. "For economic reasons only pre-assembled systems have been used, which only have to be installed at the respective construction site. " The company igus harnesses on an industrial scale with a machine park that an in-house harnessing can understandably not provide.
For this purpose, Harting industrial connectors are used, which are harnessed by igus with crimping machines. Among other things, these plug-in connectors have been designed to combine different transmission media in one joining link. Extensive accessories meet the different customer requirements. This ensures the required variability in the cable configurations. In addition it is important to ensure that disassembly or assembly, which is sometimes carried out on the mast at great heights, can be carried out easily with gloves due to the cold. This is ensured among other things by clip locks on the plug-in connector.
