Equipped for mobile living - Interior fittings for caravans need vacuum for clamping

A caravan or motor home is becoming a second home for more and more people. Manufacturers need to produce efficiently in order to meet the growing demand. This is not possible without vacuum pumps, which in this industry often come from Busch.

If you ask people taking their holiday in a motor home or caravan about their preferences, you always get the same answers. They love the feeling of independence, flexibility and self-determination that a rolling home gives them. In Europe, completely different destinations can sometimes be reached within hours, and it's not even a problem if it takes a little longer. It is possible to spend the night on the road at any time and almost anywhere. After arriving at your destination, all you have to do is find a parking space, and if you don't like it there, just keep driving.

Major trend

The rolling holiday home, whether as a motor home with its own drive unit or as a caravan for towing, is in vogue. Manufacturers have been recording rapidly growing sales for years: In Germany, the number of registered motor homes rose by 100,000 to around 450,000 between 2013 and 2017. New records were achieved in 2018 and 2019. The manufacturers' association CIVD reports "serious production bottlenecks" and "empty used car markets".

The manufacturing companies are growing and production is increasingly automated. The interior design of mobile homes is very similar to the construction of system furniture. The essential basic material – chipboard and veneer – is also the same.

Table with suction device

In the production of wooden parts, elements such as kitchen blocks, seating groups and built-in cupboards are made out of this material. CNC routers are used for cutting and milling the panels. Several such machines usually work together in a logistics chain for different work steps. The panel material is transported on belts to the clamping table of the processing machine, which has the size of the veneer panels to be processed.

The table is provided with small holes through which air is sucked out. The resulting vacuum holds the panel firmly in the processing position. It is now "stretched" on the table. Vacuum pumps are responsible for suction and can be integrated directly into the CNC centers. In mass production, however, numerous such machines are in operation. For this reason, manufacturers usually rely on a central vacuum supply, which ensures efficient and reliable operation. The noise of the vacuum pumps does not pollute the working environment; their waste heat can be efficiently recovered in the central vacuum system. Busch has many years of experience in building central vacuum systems and offers numerous suitable solutions.

The short answer: Unfortunately, it is not possible to answer this question because the beginnings of the caravan date back to antiquity, and there is probably no single inventor. There are references in historical sources to touring wagons that were on the road during Roman times. Marco Polo saw a wagon among the Tartars, which he said could be extended into a bed covered with tarpaulins. Since the 17th century personalities like Richelieu, Goethe and Napoleon traveled in two-axle residential chaises. The caravan has also long been in use among the itinerant Roma people. Inspired by this, the first tourist touring wagons were built at the end of the 19th century in the UK. They were sometimes luxuriously equipped carriages, initially drawn by horses. Shortly after the dawn of the automotive age, the British founded the first caravan club in 1907. The triumphal march of the caravan began in the USA in the 1920s. In Germany the first "Wohnauto" (car for living) was built in 1931.
