Schachtabdeckung in Tunnel

Cabel shaft cover Type H-CSC

Covers for cable and/or utility shafts in tunnel structures, square and round design

Shaft cover is resistant to surface water, load-bearing, fireproof, impervious to smoke and designed for concreting in to fit flush with the ground

Load class:
B 125 kN/D 400 kN in accordance with EN 124,
90 / 120 minute fire-rated – tested and certified (120 min. only for rectangular design)

Materials and construction:
Frame and lid trough in stainless steel V2A-1.4301/ V4A-1.4571

Frame with reinforcement attached externally plus height adjustment, fire-insulated centre strut fitted to multi-section covers, lid pre-assembled to allow reinforcement to be inserted and for subsequent concrete in-fill, lid with frame secured using three-square brass bolts, resistant to surface water, frost and weather-resistant and heat-resistant seal made from silicone foam profile. Design variations: single-section covers and covers with two or more sections with centre struts.

  • Extremely fire-retardant. F90 / I90 fire protection certificate
  • Construction height 150 mm = 90 min. / construction height 180 mm = 120 min.
  • Frame can be leveled to adjust the height to the final surface
  • Manhole cover for lifting out in 1- or 2-part design with center bar Cover screwed to frame several times with triangular screws
  • Warranty 5 years (sealing materials are subject to natural wear and tear and are excluded from the warranty).

Tested & certified

Tested and certified for enhanced fire safety requirements with a 90 / 120-minute rating for fire and smoke and for load class B125kN/D400kN in accordance with EN 124.

Utility cables remain protected in cable shafts even in the most extreme heat to maintain the supply (of electricity, water and so on) via the relevant media.

Your benefits

  • An ideal solution for tunnelling due to its high resistance to pressure and suction
  • Fulfils the fire protection requirements for rail and road tunnels, tested and certified
  • Our sealing concept allows you to maintain dry installations in your shaft structures
  • The stainless steel design provides a high level of corrosion protection and there is no "welding" of the cover and frame caused by corrosion
  • Long service life, longer service intervals and therefore lower costs due to the high material quality

Application examples

of the cable shaft cover type H-CSC

With the cable shaft cover type H-CSC, the cabling in the structure is watertight, fireproof, trafficable and impermeable to smoke and protected against external influences. The option of flush-floor installation and the construction used with load class B permits numerous areas of application, including tunnel structures and rainwater retention basins. Whether telecommunications, power supply or fiber optics - with this manhole cover, cables are safe, dry and protected from fire, while still being easily accessible for maintenance.

With a fire resistance duration of 120 minutes, the cable shaft cover meets the highest test requirements. The accessible, flush-floor model for setting in concrete also has the necessary type tests before and after the fire test with regard to load-bearing capacity in accordance with EN124.

The HAILO Professional cable shaft cover has been used successfully in these and many other buildings for years - with low maintenance requirements and the best possible safety for the cabling:

  • In the Fehrbach tunnel near Pirmasens
  • In the Damaschkeplatz tunnel in Magdeburg
  • In the Petuelring tunnel in Munich
  • In the Wertachstraße rainwater retention basin in Nuremberg
