For more road safety, the roadway and pavements in the tunnel should be cleaned regularly. This involves removing dirt, e.g. from tyre abrasion or accidents, and flushing it into the sewage system.
In addition, the road markings are cleaned, which increases the contrast of the markings to the road and improves visibility. In the process, any optical guidance devices that may be present are also freed from dirt.
High-pressure road washing bar
The three-section road wash bar developed for the TWG 600 is specially designed for road cleaning. The central telescopic extension allows the operator to view the implement in operation well. The two outer spray bars are height-adjustable and are well-suited for cleaning pavements next to the roadway. The timer-controlled automatic parking system makes moving the implement into the compact transport position easy.
