Thrubeam® D400 DS6 Pressure Release Access Cover
Verified by manufacturer 3 days ago
Composite 600 x 600 mm vehicular access cover with pressure release locking mechanism allowing safe water dissipation during floods while maintaining security.
Application
The product is suitable for use in underground access covering for transport and utilities industries, particularly in areas prone to flooding or water surges where safe water dissipation and secure access covers are required.
Description
The Thrubeam D400 DS6 Pressure Release Access Cover is a composite manhole cover designed for vehicular use, measuring 600 x 600 mm. It features a pressure release locking mechanism (PRLM) that allows water to escape safely during flood surges while keeping the cover securely locked in position. This innovative technology prevents covers from sticking up or being blown out of the ground, eliminating hazards for pedestrians and motorists.
Features and benefits:
- Allows water to dissipate safely during surges by moving up to 46 millimetres.
- Maintains security with a twin locking mechanism that allows vertical movement but prevents removal without unlocking.
- Spring-loaded frame ensures the cover returns to position after water recedes.
- Conforms to EN124:2015 Class D400 standard for vehicular composite access covers.
- Tested for effectiveness and safety under flood conditions with release at 0.5 bar pressure.
- Designed and engineered in the UK for the transport and utilities industry.
