Weights of up to 45 metric tons and their form make strip steel rolls – commonly referred to in the trade simply as coils - pretty dangerous, which means they need to be handled just as carefully as eggs. Intralogistics experts know only too well that this involves far more than moving coils from one location to another without damaging them. Parking and storing them can also be a risky business. Runaway coils or slit strips repeatedly lead to occupational accidents, some of them fatal. According to a joint study by Fachvereinigung Kaltwalzwerke (the German trade association for manufacturers of cold-rolled strip steels) and RTWH Aachen University, coils less than 275 millimeters wide should be stored in racks to prevent them from tipping over. "Naturally, it's better also to provide proper support for wider units," underlines Boris Franke, Managing Director of SpanSet secutex Sicherheitstechnik GmbH. "If a forklift truck runs into a coil, it mustn't cause a domino effect," he adds.
With this in mind, SpanSet secutex presented an entire range of efficient solutions for the safe handling and protective storage of coils at EMO Hannover 2019. Robust Coilprotect cradles made of steel minimize the risk of coils and slit strips that are stored upright falling over. "As products that are critical to safety, coil cradles must be manufactured in line with DIN EN 1090 EXC 2. Our expertise in heavy-duty lifting equipment means we are able to offer coil cradles in two sizes and numerous different lengths," says Franke. Coilprotect Altus is suitable for the long-term storage of coils in all sizes, but this high-profile cradle can only be loaded using coil hooks and coil tongs. Coilprotect Semi has a lower profile and a row of inward-facing stake holes spaced 100 millimeters apart, which is totally adequate for most coils. In the case of slit strips, which are often particularly narrow, however, this can still allow too much "wriggle room", so Coilprotect Premium has a second set of offset holes that enable warehouse staff always to position stakes close to the coil. The Semi and Premium designs can both be loaded using a forklift truck rather than hooks or tongs. Polyurethane-coated bearing surfaces designed to prevent the sensitive cradle surfaces from getting scratched are also available for all coil cradles. Last but not least, secutex Heat provides a heat-resistance buffer pad for hot processing.
