Ductile iron D400 HA104/09 access covers
Simply the best D400 access cover range available in the market. Full of patented design features that combine together to give Unite the longest life and therefore lowest whole life cost of any D400 access cover. Exceeds both BS EN 124:1994 and HA 104/09 requirements.
|For use in a Group 4 Class D400 carriageway environment|
|All fully comply with BS EN 124:1994 and are Kitemarked by BSI|
|Complies fully with UK Highways Authority specification HA 104/09 with enlarged frame flanges and corners and the inclusion of lifting points|
|A patented safety keyway prevents accidental disengagement during the lifting operation. Also compatible with standard D400 lifting keys.|
|Three point suspension on covers for non-rock stability|
|Manufactured from strong and highly durable ductile iron|
|Patented frame design with enlarged frame corners that help dissipate load|
|Patented “Framegrip” mortar gripping system built into the underside of the frame that improves the bedding mortar grip to the frame, reducing lateral shift and mortar breakdown|
|“Anti-flex” beams increase cover stiffness thereby helping to eliminate at source the main cause of cover seating wear and therefore excessive noise and ultimately catostrophic failure|
|Specially designed cover support geometry reduces movement relative to the frame and therefore seating wear|
|Specially designed frame flanges – help limit bedding mortar crack propagation|
