This unique design by Wrekin is the ideal solution when a very large access cover for D400 Group 4 is required.
Designed and manufactured to meet the enhanced requirements of Highways England’s CD534 (Formerly HA 104/09) specification and BS EN 124:2015, the Hercules™ access cover includes additional market-leading features designed to provide both greater operator safety and operational longevity.
The double triangular covers are indexed to ensure correct orientation when fitting. The cover’s M16 blank bolt can be replaced with a threaded lifting eye for mechanical lifting – the position of the bolt is at centre of mass, allowing safe and level lifts.
The covers feature a small window allowing for easy and safe inspection without the need to remove the entire cover.
Note: Additional M16 lifting points are present on Hercules cover sizes exceeding 1200×1200 Clear Opening in lieu of BS7903 Lifting Keyways, for alternative methods of mechanical cover lift.

*BS EN124 and HA 104 apply to products with a clear opening up to 1 metre. The Hercules range of access covers have a clear opening greater than this, however load capability and design features exceed the requirements of these documents.
Please note that Hercules 1200 cover is the only cover in the range to have keyholes for manual lifting.
