Vetter slewing cranes

Vetter slewing cranes optimize welding workplaces The optimization of material flow by targeted use of slewing cranes is the core competence of Vetter Krantechnik, Siegen (Germany). In 2010, a manufacturer of construction engines in Belorussia started to optimize its material flow in the entire production department by means of Vetter slewing cranes. Six of Vetter’s slewing cranes with two jib arms, each mounted onto a column, were installed in an existing hall in which welded structures are manufactured. This way each crane covers two welding workplaces, ensuring an optimal production process. This efficient concept was also implemented in an adjacent new building that was finished in 2013: Again six Vetter slewing cranes with two jib arms were installed. As a special feature, two articulated arms (on the basis of the handling crane “boy”) were additionally mounted onto the column, providing the support for welding bags. This feature ensures better ergonomics, because the working material can be slewed easily into the operator’s individual working position and is therefore always within reach. With the help of a cable conduit, this solution further contributes significantly to work safety because tripping hazards by lying cables are prevented. As a result of using the Vetter slewing cranes, the company is able to increase material throughput and productivity considerably, so that the initial costs will amortize within one year. RFID technology by I. D. Systems is ideal for use in harsh environments With the new system solution Zone Speed, I. D. Systems has expanded its comprehensive portfolio of intelligent forklift truck management systems by systematically focusing on “safety”. The stand-alone RFID product for the automatic speed reduction of industrial trucks is used in all cases where speed must be reduced without the driver being able to influence it. When entering a hazardous and safety area, the industrial truck is automatically slowed down to walking speed. After leaving this area, the vehicle accelerates back to normal speed only after the driver has given confirmation. Compared to position, distance or infra-red sensors, the use of tamper-proof and reliable RFID technology, even in harsh environmental conditions, offers a variety of options. Leuze expands its barcode reader BCL 300i series The modular barcode reader series BCL 358i by Leuze electronic has been extended with another Ethernet-based device variant, which has an integrated Ethernet/IP interface. The barcode reader can therefore be directly integrated into the Ethernet/IP network without any additional software and can be parameterised through hardware configuration (“RSLogix”). Furthermore, thanks to its integrated switch, a network can be created in a linear structure. The BCL 300i series now offers, as integrated interfaces, the three main Ethernet-based fieldbuses (TCP/IP, Profinet and Ethernet/IP), as well as a profibus. Another feature includes the available connection technologies. Depending on requirements, the user can choose between M12 plugs, spring-loaded terminal clamps or fixed connection cabling. Hence, due to its modularity, all the variations of electrical bonding are available according to individual requirements. Vahle’s new all-in-one solution for storage systems Several different standard conductor systems can be integrated into the support profile of the Vahle multi-carrier (VMT – Vahle-Multi- Träger). For example, four-pole U25 conductor rails are available as an option. The conductor rail is available with two different conductors made of aluminium/ stainless steel for maximum continuous currents of 230 and 320 A. This allows not only the electrical supply of shelf vehicles but also the implementation of long storage aisles with only one feeder. Furthermore, the compact conductor systems VKS 4, VKS 5 and VKS 6, as well as the single insulated conductor rail U15, can be integrated into the VMT in the max. 7-pole version. The structural dimensions and mechanical connection of the system solutions to the shelf structure is always identical. Thanks to this new development, suspension distances of up to 3.5 metres can be achieved. The galvanised steel profile ensures the necessary load capacity for this distance. The design of the profile provides high stiffness. For assembly, the holders for the VMT profile are screwed onto the supports of the shelving system. The carrier itself is then plugged only into the holders and clamped using spring elements. The butt joint between the support profiles is made in the same way. The compact holders for the respective conductor rail system can only be screwed into the support profile, and the conductor rails can then be pushed in smoothly. When replacing, no special tools are required. This applies when fastening the conductor rail into the carrier and when connecting the parts together. Hence, in case of damage, the affected part can be easily replaced in the centre of the storage aisle without having to dismantle other parts of the system. The VMT system has a connecting piece on the top side of the support profile which serves as an adhesive surface. Here, all current barcodes or data matrix bands can be stuck on in order to determine positioning. 52 f+h Intralogistics 3/2014
