Inspection manhole cover in ductile iron EN- GJS-500-7 conforming to norm EN
1563:2018 with load bearing capacity over 400 kN (40 tons), conforming to the load
class D400 as set out by norm EN 124:2015
FRAME
It can be square or circular in shape, with a circular net opening.
It has a EPDM gasket placed inside a groove, in order to increase stability
and eliminate any rocking or noise.
Furthermore, the hinge seating of the cover is obtained through casting.
Externally, the outside border is flanged to optimise its hold in the cement
and the insertion of the anchoring bolts.
COVER
It is round-shaped, hinged to the frame with maximum opening of 110°, 90°
is the safety position (automatic locking), there is the possibility to remove
the same cover without disassembling the hinge.
It presents an elastic closing system provided with an elastic bar built
into the cover, which creates an automatic opening/closing system. This
can be carried out using building clays. A high stability is guaranteed by
the machine-working of the contact surfaces(turning process), by selfcentering
guides, placed under the cover with double stops.
The upper surface is designed to be non-skid to allow the complete flow of
water and avoid the creation of ice.
