Non rocking
3-point suspension design, for silent operation.
Meets the
requirements of CD 534 v0.1.0 (formerly HA 104/09).
Captive hinges reduce theft risk whilst allowing easy
lifting.
The enlarged frame corners help to dissipate loads onto the
foundation, providing a longer service life and increased reliability.
Frame gussets are supports which reinforce the corners where
the frame sections meet, distributing stress evenly, preventing damage to the
frame or the access cover.
Keyway lifting points are provided on the frame for safe
handling.
Holes in the frame flange where mortar can pass between the
underside and top side, creating an interlock, providing greater strength.
Reversible hinge allows the grating to hinge with the
direction of the traffic flow, improving safety.
Surface texturing above and below the flange enables better
mortar engagement, reducing any lateral movement which could result in
cracking.
Available Options: Screw locking deters unauthorised
access to the chamber. An extended shank socket set is required to engage the
locking screw.
Notes:
Where 3-flange D400 Gully Grate assemblies are employed, we
recommend that they are installed against a kerb, not in an open highway
location.
The D400 load capability of these Group 3 products also
offers the benefit of making them suitable for exposure to Group 4 traffic
types. Where 3-flange D400 Gully Grate assemblies are employed, we recommend
that they are installed against a kerb, not in an open highway location. All
values stated are nominal within 2.5% tolerance.
