High-pressure cleaner for municipal vehicles

Cleaning with water under high pressure and swirling dirt poses enormous challenges. To meet this challenge, the German company Fiedler Maschinenbau und Technikvertrieb GmbH has developed the FSB 1.500 / 2.600 double spray boom, which is installed in front of the vehicle. This innovation won the bronze manus® award in 2023. The vehicle cleans floors with high water pressure using side nozzles, a centre section and electronic, switchable high-pressure underfloor nozzles. The engineers use a drylin® W double rail WS and drylin® W pillow block for the telescopic function. The vehicle is used by local authorities and municipal service providers to clean dirty roads, pavements and squares.

Problem

The FSB 1.500 standard spray boom is equipped with optional telescopes on both sides, each of which can be extended 500mm to the right and left. The use of these telescopes increases the working area, which is an advantage when cleaning surfaces as fewer passes are needed. It is even possible to clean narrow areas, such as between park benches and rubbish bins, without any problems as the vehicle can go through in one straight line without additional steering movement.

However, the 500mm telescope is too short, forcing users to rework the affected areas manually, which is time-consuming. The aim of the German company is to double the telescopic working range. The bearing must be wear-resistant, insensitive to dirt particles and mixtures of water and dirt particles, last for a long time, be easy to replace in the event of damage, be lighter and increase the skidding speed and reduce the effort required for the skidding motor.

Solution

The double spray boom can be telescoped continuously by 500mm on both the right and left side. Thanks to this adaptability, the driver can clean large areas. Fiedler Maschinenbau und Technikvertrieb GmbH doubled the telescopic working range so that the operator can also clean thoroughly in all the spaces in between.

To do this, the company opted for the drylin® W double rail and drylin® W pillow block from igus®. The corrosion-free components are not only wear-resistant and insensitive to water and spray mist, sand, gravel and brake drive. They are also robust enough to withstand heavy impacts and vibrations when driving over curbs and cobblestones. At the same time, they are light enough to maximise the load capacity for the cleaning water they carry.
