Hercules™ D400 manhole covers
Our Hercules range has been designed as the ideal solution when a very large manhole cover is required for a D400 Group 4 environment.
The products have been designed and manufactured to meet the requirements of BS EN 124:2015. Additionally, the covers include 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.
