Telescopic square cast iron manhole cover 325x325, KL.D400 (40T), bolted, for d315 pipe, painted W0600-1320-0100-000

Telescopic Cast Iron Manhole Cover – Robust and Safe Solution for Infrastructure

This square telescopic manhole cover, manufactured from durable cast iron, is a reliable component for road and sewer infrastructure. Designed for installation in manhole chambers, it ensures safe access to underground installations, in areas with high pedestrian and vehicular traffic. With a load class D-400 (40 tons), it guarantees resistance to heavy loads, making it ideal for use on roads, parking lots, and sidewalks.

Design and Application

The manhole cover is designed in accordance with standard PN-EN 124-2, confirming its high quality and compliance with European regulations. Its telescopic design allows easy height adjustment to match the surface level. The cover is secured with hex socket screws, providing additional protection against unauthorized access and theft. A d315 mm pipe, 500 mm in length, beveled for easier installation, is included. The pipe is fastened with 3 screws.

Applications include:

• Sewage manholes
• Telecommunication manholes
• Water meter manholes
• Other underground installations requiring service access

Advantages and Benefits

• Strength and Safety: Load class D-400 ensures resistance to loads up to 40 tons, guaranteeing safe operation even in high-traffic areas.
• Durability: Made from gray cast iron, the cover is resistant to corrosion and mechanical damage, ensuring long service life.
• Security: The screwed-on cover prevents unauthorized access and minimizes accident risks.
• Easy Installation: The included d315 mm pipe with beveled edges simplifies and accelerates installation.
• Standards Compliance: Meets requirements of PN-EN 124-2, ensuring high quality and safe usage.
• Anti-Corrosion Protection: Standard anti-corrosion coating extends product life and reduces maintenance costs.
• Positioning Guides: Additional cover positioning guides ensure stable seating and precise alignment.

Note: The product has fire reaction class A1 – it is non-combustible. The load-bearing capacity of the body surface is Pb ≤7.5 N/mm², and the manhole’s load capacity is 400 kN with maximum permanent deformation ≤0.2 mm. Cover locking security meets requirements of h = 0.006 mm at F = 220 N.
