Bridge inlets

To prevent the emergence of the phenomenon of " aquaplaning " or ice on bridges, water from the surface must be quickly and effectively drained. Using the new bridge inlets Multitop ® HSD can significantly improve the performance, safety and efficiency of drainage .

The upper part of the bridge inlet has an adjustable height, can move sideways and rotate. Grates are equipped with screwless snap, and frames with cushioning inserts. In a closed frame there is the possibility of the clearance designed holes to drain water during construction work. Inlet systems are offered in versions
HSD -2 300 x 500 ( grate size 300 x 480) and HSD -5 500 x 500 ( grate size 500 x 559) .
Both versions have load class D 400 according to DIN EN 124 / DIN 1229 .

Bridge inlets Multitop ® achieve high performance hydraulic thanks to the special construction of the grate and appropriate adjustment of the frame, which eliminates bottlenecks .
This avoids clogging them, increasing the safety of road communication and lengthen maintenance intervals. Maintenance of dirty or hard-working bolted connections becomes unnecessary, as new drains are equipped with a dirt-resistant latches secured with stainless steel.
Grate and frame are connected by a hinge with opening angle of 110 º. Ease of use features HSD technology allowing for smooth height adjustment and moving the eccentric side to side. In addition, the possibility of a 360 ° rotation allowing precise inlet adjustment at the height of the road surface and parallel to the cover. Sturdy shock-absorbing inserts in the frame flush system reduce surface pressure and thus ensure sustainable functioning without knocking.
