Composite sewer manhole / technical access cover | hatch | Ø900mm | D400 | SMC | black

The cover is classified as D400 and complies with the EN124 standard. Covers of this class are used on carriageways, car parks, industrial areas and other locations exposed to high vehicle loads.

SMC composite is non-metallic and has electrically insulating properties. The material also helps dissipate static electrical charge and may therefore be useful in installations where reducing the risk of electrostatic discharge is important.

The cover can be used on carriageways, industrial areas, petrol stations, storage yards and other locations where light or heavy vehicles operate.

The rubber sealing ring and side sealing structure are designed to reduce the penetration of water, gases, odours, oil or other liquids between the cover and frame.

The specified -60°C...+150°C range describes the temperature resistance of the SMC material used in moulded products. Actual operating conditions at a specific installation location also depend on sealing elements, fixing components and the complete structure.

• D400 load class suitable for high vehicle loads.
• EN124 standard clearly defines the manhole cover load class.
• Ø900mm clear opening provides a large access area.
• SMC composite construction is corrosion-resistant and does not rust.
• Resistance to fuel, oil and chemicals makes it suitable for industrial areas.
• Sealing system helps protect the manhole from ingress of water, liquids and odours.
• Lockable bolts protect against unwanted opening of the cover.
• Raised anti-slip surface improves grip.
• Electrically insulating material does not have the electrical conductivity typical of metal covers.
• Lower weight than cast-iron structures may simplify transport, installation and maintenance.

• Correctly prepared base required: D400 performance also depends on correct installation of the frame.
• Large external dimensions: the frame diameter is approximately 1020mm, so sufficient installation space is required.

A technical manhole is installed in a trafficked area of an industrial site. A large access opening, resistance to heavy vehicle loads and resistance to a corrosive environment are required. The composite cover is installed into a properly prepared base. The rubber sealing ring helps reduce the ingress of water and other liquids, while the lockable bolts prevent the cover from being easily opened without tools.

D400 according to EN124.

The clear opening diameter is Ø900mm.

The outer frame dimension F is 1020mm.

The overall construction height is 100mm.

SMC composite material.

The SMC composite structure does not rust like steel or cast iron, making it suitable for corrosive environments.

Yes. The SMC material is resistant to petrol, diesel fuel, lubricants and many chemicals.

The construction uses lockable bolts operated with a hex key.

Yes. The cover surface has a raised anti-slip structure.

The load class is determined not only by the cover itself, but also by the correctly installed frame and supporting base. The installation structure must reliably transfer vehicle loads to the surrounding base. Before installation, the clear opening, frame and installation dimensions must be checked and all construction and engineering requirements applicable to the specific site must be followed.
