The heavy-duty specialist Vollert from Weinsberg, Germany, is supporting the agricultural machinery manufacturer JACTO in Brazil with the construction of a new combined powder and wet paint coating system. Large parts up to 10 m long, 2.5 m high and weighing 4 tons are coated, including for large coffee and sugar cane harvesters as well as planting and fertilizing machines. To speed up the time-consuming dip coating process, product carriers can be combined for smaller workpieces and separated again for larger workpieces.

At the Liebherr plant in Ehingen, Vollert planned and built a new ballast painting plant with friction wheel and rope conveyor technology for the coating of crane ballast elements. These are used as counterweights for mobile lattice boom and telescopic cranes with lifting heights of up to 245 m. Depending on the product carrier, elements weighing up to 20 tons can be coated in an overhead, suspended manner. A total of 25 product carriers are in circulation.

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.

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.

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.

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.

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.

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.
