|
| Every
wiping system product has been especially developed for Rolling
Stock. |
| The
research of the proper materials, thermical treatments and
seals enable the complete system to reach a high level of
reliability. |
|
| -
air-motor |
| The
movement reversal system is integrated into the air-motor
and therefore the pneumatic scheme is simplified. |
| The
reversal is adjustable to comply with the different sweeping
angles required. |
| The
shock absorbtion is air-assisted and can be complete with
an elastomer shock absorber when necessary. |
| Endurance
tests have been successfully carried out up to 6 million cycles
without failure. |
|
| -
wiper arm |
| In
case of parallel sweeping, the mechanism that moves the blade
parallel to the glass is built into the arm, and thus protected
from impacts. |
| Either
jets are settled along the wiper-holder, or they are fixed
into the upper part of the arm. |
| For
routine maintenance, the arm can be raised from the glass
when it is in the parked-position, and remains raised. |
|
| -
washing pump |
| Its
liquid flow is sufficient to feed several arms. |
| -
control desk |
| Every
pneumatic component fulfils railway regulations. |
