Manhole cover assembly
A manhole cover assembly removably supported by a manhole skirt or rim wherein when the manhole cover assembly is removed from the manhole skirt or rim an individual can access one or more components (e.g., underground fuel storage tank) through an opening in the manhole skirt or rim. Preferably, the manhole cover assembly is light weight and very strong so that there is little or no deflection of the cover of the manhole cover assembly when subjected to a predetermined load. Preferably, the manhole cover assembly is adapted for use in refueling stations to withstand the load placed thereon when a refueling tanker or other vehicle runs over the manhole cover assembly with little or no deflection of the cover of the manhole cover assembly. Preferably, the assembly forms a liquid tight seal with the manhole skirt to prevent liquid from passing into the storage area below the skirt.
