Abstract: A manhole cover for manholes, sewer accesses or drainage channels, including a reinforcing element and a body made of plastic which is connected to the reinforcing element. The reinforcing element may be constructed from intersecting, vertically aligned elements. Corrugations may be formed in the reinforcing element. The reinforcing elements may be arched and may include an outer encircling strip and a central plate, which are each connected to the body made of plastic. The reinforcing element rests on a bearing surface on the manhole, sewer access or drainage channel when the manhole, sewer access or drainage channel is closed by means of the manhole cover. The body made of plastic includes ribs, which extend perpendicularly or at an angle of more than 45° to the surface surrounding the manhole cover, sewer access or drainage channel when the manhole, sewer or drainage channel is closed.
