The road manhole cover h638_190 is a high-performance crowning device made of GJS-500-7 ductile iron, designed to meet the needs of utility managers and municipalities operating in heavy traffic contexts. Thanks to the D400 load class, the product solves issues related to stability and road safety, preventing rocking and annoying noises thanks to the tripod support system of the covers. The structure with triangular covers with sequential opening facilitates inspection operations on large compartments, while ensuring secure locking via a bolted steel rotating bolt.

User benefits
Dynamic stability: The tripod support of the covers eliminates oscillating movements under the passage of vehicles, reducing mechanical wear and noise pollution.
Operational safety: The 90° locking system of the hinges prevents accidental closure during inspections, protecting the integrity of technical personnel.
Prevention of theft and tampering: The rotating bolt with protection cap limits access to authorized operators only, equipped with a specific key.
Easy installation: The integrated lifting eyes and the slotted perimeter flange allow for precise positioning and a durable structural anchoring to the foundation.
Certified durability: Compliance with ISO 9001:2015 and UNI EN 124 ensures a prolonged life cycle even in heavy traffic conditions (group 4).
Scope of application
The primary use of the h638_190 manhole cover concerns the carriageways of main roads, stopping areas, and parking lots for all types of vehicles. Its wide clear opening configuration (1000x1200 mm) makes it ideal for access to inspection chambers for technological networks, complex hydraulic nodes, and service tunnels where the passage of personnel or bulky equipment is necessary. The certified D400 resistance allows for its installation in all urban and extra-urban contexts subject to frequent heavy vehicle transit.
Why Choose It
This model represents the correct choice when simplified access to large rectangular compartments is required without sacrificing maximum structural stability. It is suitable for specifications requiring high safety standards, such as the mechanical locking system and the hinge with safety lock. It is preferable to standard solutions when maintenance requires frequent openings: the configuration of sequential triangular covers reduces the physical effort of the operator, ensuring that each element remains attached to the frame during inspection.
FAQ
What is the advantage of sequential opening compared to a single cover?
Sequential opening allows managing a very wide clear opening by dividing the weight of the cover into smaller and more manageable triangular elements. The master cover unlocks the subsequent ones, ensuring an orderly and safe access procedure for the operator.
Is the product compliant with current road safety regulations?
Yes, the manhole cover is produced by an ISO 9001:2015 certified company and is rigorously tested according to the UNI EN 124 standard, guaranteeing belonging to class D400 for installation in traffic areas.
What is meant by tripod support?
It is a three-point support system that guarantees the stability of the cover in the frame even in the presence of slight irregularities, eliminating the "clinking" phenomenon (metallic noise) and the rocking typical of four-point support closures.
