ODM Metal Manhole Cover EN124 D400 Ductile Iron GJS-500-7 - EN 1563




Cast iron manhole covers are generally divided into round and square. In the urban area, circular is generally used, because the round manhole cover is not easy to tilt, which can better protect the safety of pedestrians and vehicles. The use of a circle is mainly due to the fact that the circular manhole cover has the same length through each of its centers, so that if the manhole cover is rolled up by the passing vehicle, the diameter will be slightly smaller than the wellhead below. Wide, the manhole cover will not fall into the wellhead. If square is used, because the diagonal of the square is obviously longer than the length of each side, when the manhole cover is rolled up, it is easy to fall into the well along the diagonal direction of the wellhead, causing security risks. If the wellhead is rounded or significantly smaller than the manhole cover, the square manhole cover will not fall into the well. This involves the problem of utilization and savings of a material. The use of the wellhead depends on the size of the wellhead. If a square manhole cover with a much larger area than the wellhead is to be installed on it, then the material utilization and practical value are naturally not more effective than using a circular manhole cover directly, which not only saves the material of the manhole cover, but also The safety of the wellhead is ensured and used in the countryside and cable wells, generally square, which can better prevent the entry of liquids such as rainwater.




Ductile iron GJS-500-7 - EN 1563 manhole cover, produced according to provisions of the latest edition of the UNI EN 124, loading class D400, consists of a square/octagonal frame, as supporting base and circular at the top, corresponding to he street level, provided with: a continuous perimetral outer winglet of a width not less than mm. 20, to obtain a greater supporting base and allow a better anchorage to the foundation also by means of elongated holes and/or holes created along the perimeter and through the use of any mechanical means for fixing to the manhole; “U” shaped internal seat; elas-tomeric cushioning insert, anti-noise and anti-rocking, suitably shaped to frontally withstand the edge of the cover and absorb vibrations; hinge housing with closed bottom and cover locking system in open position. Cover of circular shape, self-centering in the frame, provided with: slot, for the inserting of the opening and lifting key, locking system in steel realized by means of a rotating bolt, bolted with helical spring of contrast; an appendix suitable to ensure the positioning of the cover to the frame in the hinge compartment without preventing the extractability of the cover; central and circumferential space for the insertion of any inscription (e.g. contractor entity + etc.); identification of the outer shape of the frame and of the product size, expressed in cms.; anti-slippery reliefs.
