D400 hinged and lockable access cover and frame
We were recently approached by global engineering consultants Mott Macdonald, who are working with Thames Water, to help design an easy-access chamber opening as part of an equipment upgrade across the streets of Greater London.
The key requirements of the job specified that the access covers must be strong and durable to cater for the high volume of traffic they would encounter, as well as being light enough for one worker to lift safely.
In addition, very specific dimensions were requested: 1200 x 750mm, 1500 x 750mm and 1800 x 750mm.
We created a new spec for our D400 range of covers and frames. These are made from high strength ductile iron and include hinges for easy opening and lockable covers for security.
As well as being strong and durable, the D400s also feature our unique SmartGrip TechnologyTM anti-slip tread pattern as standard, designed to provide a high PSRV skid resistance value >70, as well as a three point suspension for non-rock stability.
The installation on site was fast and smooth, and the final product looks very smart.
Needless to say the client was very pleased with the product we were able to supply, as well as the speed and professionalism of the installation.
