Concrete cable duct HRI 300-250. Cast iron diamond plate. L=2.25m. D400KN

The cable ducts are of type I (self-supporting ducts) according to the EN1433 standard. The prefabricated U-channels are made of self-compacting and reinforced concrete (C 55/67). Due to its design, the cable ducts have a built-in resistance of strength class D, 400 kN. The proposed resistance is guaranteed by the whole. The cable ducts have a tongue and groove connection and a recess for a safety joint (SF). If the design is liquid-tight, this recess must be sealed. Galvanized steel pins ensure an improved connection and straight-line installation. The tops of the gutter are equipped with integrated edge protection in galvanized steel, anchored in the concrete. The cable duct complies with the European Standard EN1433. Dimensions: length 2.25 m; internal width 220/240 mm (bottom/top); outside width 400/380 mm (bottom/top); internal height 250 mm; outside height 320 mm. Weight 392kg. Equipped with 2 lifting loops. Pre-assembled cast iron diamond plate made of nodular cast iron FGS 500-7, length 75 cm. The anti-slip diamond plate is supplied bolted to the cable duct: 2x bolted with stainless steel bolts (in other words 6x bolted / drain duct), the stainless steel bolts are anchored in sleeves that are connected to the reinforcement. The diamond plate complies with load class D, 400 kN according to European Standard EN 1433. The self-supporting drain channels allow installation without a lateral concrete jacket (only a foundation is necessary). Installation manual available on request.
