Truck trailers are useful, but also big and heavy. This does not make their transport in the paint shop easy. Giga Coating GmbH recently built a completely new surface treatment plant in Twist. Here, up to 15.7 m long and 9 t heavy large parts are not only coated, but also blasted, dipped, swiveled and heat treated in hanging furnaces. The automated circulation principle creates capacities for up to 100 trailers and special parts per day in two construction stages.
Weld, paint and fit wagons and trailers in one line
The Brazilian manufacturer Randon has built a 500m long combined welding, painting and assembly line for trailers and railway wagons in the state of São Paolo. Vollert has developed a heavy-duty material flow concept consisting of 13 combined rope conveyor drives, two moving distribution transfer platforms and the control system for the individually timed forward feed.
Large-part painting systems designed around the corner
For LEWA as a special pump manufacturer and HAMM as a manufacturer of rollers for road construction and earthworks, Vollert developed and installed new floor-guided and overhead material flow systems for surface coating of parts weighing up to 12 tons. While high cycle times are crucial at HAMM, at LEWA for the first-time workpieces weighing tons travel 90° around the corner and thus enable an extremely compact system layout.
Low-loader manufacturer Faymonville dispatches components weighing up to 12 tons through its overhead painting plant in Luxembourg. The material flow concept also comes from a heavy load expert – from Vollert based in Weinsberg. The control system supports automatic operation as well as the manual transportation of parts. Friction wheels facilitate the space-saving plant layout.
In the new Siemens AG Austria coating center, metros and passenger carriages are automatically transported via a central transport system to the individual coating treatment booths. The transfer table allows for flexible arrangement of individual processing stations and offers the highest level of safety for crossing passenger traffic.
Vollert manufactures transfer cars for coating 13,000 carriages annually
The Tikhvin Railway Car Building Plant (TVSZ) is currently building a state-of-the-art plant for assembling open- and closed-top freight carriages in the Russian town of Tikhvin. To this end, Vollert Anlagenbau from Weinsberg was commissioned to manufacture four transfer cars with payloads of between 70 and 100 tons. A heated enclosure installed on top of the cars provides optimal protection against the elements.
Friction wheels transport large gearboxes for painting
The SEW-EURODRIVE drive automation system by Bruchsal relies on a simple, flexible material flow system by Vollert Anlagenbau for coating large gearbox units weighing up to 3.5 tons. It combines the advantages of Power&Free systems and requires significantly fewer system components. Nevertheless, comparably high cycle times are possible.
Liebherr breaks new ground with a new large-scale paint shop for hydraulic excavators: The components, weighing up to twenty tons, are conveyed through the system on a guided track while freely suspended. A special drive solution ensures optimal protection against explosion in the painting and drying booths.
F. X. Meiller Fahrzeug- & Maschinenfabrik commissioned its new facilities for coating large items in early July. Two 70 m-long painting tunnels installed in parallel offer space for 14 stations and can each take up to 12 items weighing 8 tons apiece. Two chain conveyor systems from Vollert provide the required pulling force.
At Wirtgen GmbH in Windhagen, world market leaders in the field of cold milling for road construction, components weighing up to 30 tons are freely suspended. The steel construction of the 230 °C furnaces is completely separated from the transport steel construction to protect against energy losses. This is made possible by special drive technology. Even with the heaviest loads, it allows for gap bridging of 70 cm. In addition, it is wear and explosion proof. The system was designed by Vollert Anlagenbau in Weinsberg.
50 tons of explosion-protected parts painted while suspended
With a new painting plant, Liebherr is setting the standard in commercial vehicle construction. At the plant in Ehingen, parts from mobile and crawler cranes weighing up to 50 tons will be painted while suspended in mid-air. Vollert Anlagenbau from Weinsberg is developing the intralogistics for this. Wirtgen and SEW-EURODRIVE are just two of the companies also backing the new technology.
