Documents
An innovating conception ensuring the stability of the cover or the grating in its frame was developed for the PARXESS manhole covers and DEDRA 400 gratings ranges.
The principle takes back, on the one hand the used concept for the AKSESS range (3 points with oblique seatings ensuring the stability during the vertical solicitations.), to which others seatings are added, also oblique, but in another plan, enabling to obtain a good stability during the horizontal solicitations. (Passage of vehicles.)
This seatings system enables to ensure a perfect stability of the cover or the grating in its frame at the hands of engendered constraints by the passage of vehicles and thus to guarantee the silence of these products in service.
This also enables to offer a good durability of the manhole covers and gully grates by removing all movements of the cover or the grating in its frame, frequent cause of premature degradation.
The DEDRA 400 gratings use the principle of stability of PARXESS type (C250), dimensioned in relation with the constraint level of the D400 class.
The alveolate broad flanges of DEDRA 400 gratings enable to obtain a good bedding as well as a reduced transmission of the loads to the structure located under the gratings.
The various versions of frame enable to choose the version most adapted according to the installation confines.
- Frame equipped of 4 flanges for multi-directional collection or 3 flanges for installation along a kerb.
- Frame with total opening of 400 mm or frame with mudpan bearing plate and centring studs pipes and 400 ND plastic extensions.
