Tunnel washer front arm to clean tunnel sections

On the front group are installed the rotary heads that ensure the cleaning through the abrasive action of the rotary brushes supported by the constant jet of cleaning solution (water + concentrate cleanser). The rotary brushes of the BLT 3000 road tunnel washer arm are driven by independent hydraulic motors while the multidirectional movement functions of the arm are controlled by means of hydraulic pistons. It is also equipped with a shockproof valve on the rotating cylinder of the arm, in order to provide cushion effect when backing up in an uncontrolled way. On each head it is also installed a group of ultrasonic sensors necessary for the positioning of every single head at the beginning of cleaning process.

(distance adjustment of the brushes from the wall). Each head is also equipped with a hard PVC type protection. These protections are installed in order to limit the dispersion of the cleaning solution sprayed towards the wall thus preventing its dispersion into the pavements.
