Over 30 years of experience in developing and construction of tunnel cleaning vehicles

Efficient, quick and thorough tunnel cleaning has gained more and more importance due to the
permanent increase of traffic volume. The new concept of ZELLINGER tunnel washing vehicles ensures quickest and most efficient cleaning.

Special vehicle for quick cleaning of tunnel wall, roof and lightings, underpasses, supporting walls and so like. Cleaning makes tunnel more safely and reduce the running costs of tunnel considerably because less light and less ventilation are needed.

2 washing brushes are normally fitted to provide a washing width of up to 4.50 m during a single pass. On request, it is also possible to fit only 1, or a total of 3 brushes.

Each washing brush mounted on an arm which can be raised and lowered hydraulically, and can be swivelled laterally outwards and inwards Brushes axial hydraulically rotable by a minimum of 180° . Control of superstructure units over a central, portable control panel. The ceiling of the tunnel can also be cleaned. Lighting units can be cleaned at the same time without giving rise to problems.

Cleaning agent is added to the pure water through injectors.
Hydraulically slewable spray protector shield with on the end mounted high pressure nozzle bar. Tank capacity according to the GVW of chassis. The tunnel-washing body can be mounted on the chassis either permanently, or as a removable unit. Driving speed between 500 m/h and 7,000 m/h. Hydraulic driving drive, which allows this minimum speeds.

The effectiveness of cleaning depends not only on the frictional effect of the washing brushes, but also on the use of high-pressure water and on the length of time allowed for the sprayed-on cleaning agent to act. The supporting vehicle can be any standard chassis which is fitted with the necessary additional equipment.
