The rectangular manhole cover h638_112 is a high-resistance professional covering device, designed for the securing of large manholes and inspection chambers. Made entirely of ductile iron, the product complies with the UNI EN 124 class D400 standard, guaranteeing a load capacity of 40 tons, ideal for road carriageways and heavy traffic areas. The structure is characterized by a system of 4 triangular covers with tripod seating, a geometric solution that eliminates rocking and acoustic vibrations. The rectangular frame integrates a continuous external peripheral flange, complete with slots and holes for deep structural anchoring to the foundation via anchor bolts. Security is managed by a sequential opening: the "master" cover with a lock unlocks the subsequent slave modules equipped with a locking plate.

User Benefits
Superior Stability: The tripod seating of the triangular modules ensures that each element is perfectly still in its seat, eliminating metallic noise as vehicles pass.
Facilitated Access: The clear opening of 100x150 cm allows for easy operation on complex utility systems (electrical control units, hydraulic nodes) with bulky equipment.
Security against Vandalism: The key system and sequential locking plate prevent unauthorized opening or tampering with each individual module.
Operator Protection: The automatic 90° lock during opening prevents accidental closing, ensuring maximum safety during maintenance phases in the manhole.
Indestructible Anchoring: The frame with a continuous flange on four sides distributes dynamic stresses evenly onto the concrete, preventing cracks and road subsidence.
Scope of application
The h638_112 model is the standard solution for large technological networks, primary sewage maneuvering chambers and logistics terminals. Thanks to its large passage surface and D400 certified resistance, it is perfect for installation in main road carriageways, bus stopping areas and heavy vehicle parking lots, where structural safety and ease of inspection are essential requirements.
Why Choose It
Choosing this manhole cover means opting for a robust and silent product. Despite the massive weight of 410 kg, the subdivision into 4 triangular modules makes each single opening manageable for technical personnel. It is the ideal investment for those looking for a wide-clearance manhole cover capable of reducing post-installation maintenance costs, thanks to the precision of the joints that prevent premature wear of the edges and the frame.
FAQ
What is meant by "sequential opening"?
It is a mechanical safety system: only the first cover (master) is equipped with a lock. Once opened, it physically releases the locking plate of the next module, allowing all covers to be opened only by following a predetermined order.
Is the manhole cover suitable for areas with heavy traffic?
Yes, the D400 class is specifically regulated for use on flowing roads, including hard shoulders and areas accessible to trucks and heavy vehicles, withstanding loads up to 40 tons.
Are the hinges removable?
The hinge system is designed to ensure safe articulation of the covers up to 110°. Depending on the maintenance needs, the modules can be managed individually to completely clear the net opening of the manhole chamber.
