Frames<\/h2>\n\n
\n
\n

The solid frames for ZEKAN<\/strong> covers have been oversized so that they can be used together with the covers even in the most demanding conditions. The frames are simply joined with a proven 8-point fastener system and the option of fixing with a construction bonding agent to ensure the joint is permanent. The frame design allows for customised cover assemblies starting with the smallest 335 x 600 clearance solution, with no upper limit, only depending on the specification of the installation. <\/p>\n<\/div>\n\n\n\n

The material for the production of covers is self-extinguishing, dimensionally stable, has high surface hardness, is hygienic, thermally insulating and non-magnetic. The covers can also be machined with conventional metal tools. <\/p>\n\n\n\n

The cover locking is solved in the standard version by means of a screw with metric thread and threaded sleeve mounted in the manhole body. It is possible to select a version with a classic M10 hexagon head screw or SECURITY<\/strong> TORX<\/strong> screws. <\/p>\n<\/div>\n<\/div>\n\n

In-paved covers<\/h2>\n\n

Cast iron covers in the basic load classes are also used when the requirements for the uniformity of the cover design when installed in interlocking concrete pavement are met.<\/p>\n\n\n\n

A higher version of the perimeter frame shall be used so that it is flush with the stainless steel trays, which can be paved with paving to 10 cm high. If lower paving is used, such paving shall be underlain by a layer of inert material to the required height. <\/p>\n<\/div>\n\n\n\n

ZEKAN cast iron cover load capacity<\/h2>\n\n

\"\"<\/figure><\/div><\/div>\n\n\n\n
\n

The distribution of the load capacity of covers and related structures is governed by EN 124<\/strong>, which distinguishes 6 load classes, marked with the letters A<\/strong> to F<\/strong>. The ZEKAN<\/strong> cable manholes system allows the use of the 2 most common load classes B125<\/strong> (12.5 tonnes) and D400<\/strong> (40 tonnes). <\/p>\n\n\n\n

The suitability of the use of each type is described in the above mentioned standard. The choice of a given load class is to some extent the responsibility of the responsible designer, depending on the specific conditions of the cable manhole location. The following figure is for basic orientation only. <\/p>\n<\/div>\n<\/div>\n\n
