The h638_103 road manhole cover is a high-performance covering device designed for infrastructures subject to heavy loads, in compliance with the UNI EN 124 class D400 standard. Made of ductile iron by an ISO 9001:2015 certified company, this model stands out for its configuration with two triangular lids with tripod support, a geometric solution that eliminates the root cause of rocking and noise when vehicles pass. The structure is equipped with a rectangular frame with a continuous perimeter flange, optimized for deep anchoring via anchor bolts. Operational safety is guaranteed by a sequential opening system with a bolted rotating latch on the master lid, a 90° safety block, and hinges that allow safe articulation without preventing the total removal of the lids for extraordinary maintenance operations.

User Benefits
Absence of Noise Pollution: The tripod support of the triangular lids ensures that the manhole cover remains perfectly still under the passage of tires, eliminating the annoying metallic noises typical of unstable manholes.
Master-Slave Locking System: The integrated locking plate forces sequential opening, ensuring that the chamber is accessible only through the use of the key on the main lid.
Advanced Mechanical Protection: The rotating latch is housed in a compartment with a recessed protective cap, preventing the mechanism from being obstructed by tar, soil, or road debris.
Safety for Operators: The automatic 90° block prevents accidental closing of the lids during inspections, while internal maneuvering eyelets facilitate the lifting of the half-lids.
Structural Anchoring: The continuous external flange with slots for anchor bolts ensures a uniform distribution of loads, protecting the integrity of the surrounding road surface.
Field of Application
The h638_103 manhole cover is the ideal choice for high-traffic roadways, hard shoulders, heavy vehicle parking lots, and industrial areas. Thanks to the large clear opening of 700x800 mm, it is perfect for large chambers dedicated to sewage, water, or technological networks that require frequent inspections and a certified resistance up to 40 tons of static and dynamic load.
Why Choose It
Choosing this model means investing in an extremely robust and durable component. The weight of 108 kg, combined with the precision of ductile iron, guarantees a stability that does not decline over time. It is the definitive solution for municipal utilities and road companies that intend to eliminate maintenance interventions related to the rocking of manhole covers, while offering a key locking system that prevents vandalism or unauthorized inspections.
FAQ
What is meant by "tripod" support?
The tripod system uses triangular geometry to ensure that the lid always rests on three points of the frame. This physically prevents any oscillatory movement, making the manhole cover much quieter and more stable than traditional square models.
Is the key lock included?
Yes, the master lid is equipped with a steel locking system with a bolted rotating latch. The dedicated key is included and allows for the unlocking of the sequential opening of the two half-lids.
Is it possible to remove the lids to facilitate work in the chamber?
Certainly. The articulated appendages are designed to keep the lid secured during normal opening, but they allow for the complete extraction of the half-lids once they are slid out of the hinge compartments, completely freeing the clear opening of the chamber.
