Heavy-Duty Cable Chamber Frame

A heavy-duty cable chamber frame is a crucial structural component located at the top of a cable chamber, designed to provide a stable and durable support for heavy-duty covers. It is engineered to withstand the loads and stresses associated with pedestrian and vehicular traffic, including on sidewalks, residential roads, and high-traffic public or industrial areas. Its robust construction ensures long-term stability and safe use of the cable chamber in both public and private spaces.

This frame is entirely made of steel and internally filled with reinforced concrete, significantly increasing its strength and resistance to damage. The concrete used is of D400 class, meaning the frame is rated to handle loads up to 40 tons. This makes it ideal for locations with heavy traffic, such as residential zones, housing estates, parking lots, industrial roads, public roads, and walkways with frequent vehicular movement. The frame is installed on the chamber body using concrete mortar, which provides excellent stability and long-lasting performance.

In addition to its load-bearing function, the frame enhances the aesthetic finish of the cable chamber opening. Its design integrates seamlessly with the surrounding surface, reducing the risk of accidents and disruptions to pedestrian and vehicular traffic. The D400 concrete class ensures resistance to environmental conditions and mechanical wear, offering long-term use with minimal maintenance.

Concrete Load Classes

• Concrete of class A15 is designed to withstand loads of up to 1.5 tons. This class is typically used in areas with very low vehicle traffic or where loads are minimal—such as footpaths, pedestrian zones, or private green spaces. It is not suitable for areas accessed by motor vehicles.

• Concrete of class B125 is suitable for loads of up to 12.5 tons. It is used in areas with moderate traffic, such as roadside shoulders, residential parking lots, or smaller estate roads, where vehicle movement is more frequent but not intensive.

• Concrete of class C250 is rated for loads up to 25 tons. It is designed for use in areas with heavy vehicle traffic, but not as intense as highways. Common applications include urban roads, service roads, or areas where delivery vans and light trucks operate regularly.

• Concrete of class D400 represents the highest strength category in this classification and is capable of withstanding loads up to 40 tons. It is used in high-traffic environments, such as main roads, highways, industrial zones, and maneuvering areas where heavy trucks and transport vehicles are common.

Selecting the appropriate concrete class is essential, depending on surface type and traffic intensity. For areas requiring maximum strength and durability, the heavy-duty D400 frame is the optimal choice, ensuring safety, longevity, and resistance to wear.
All frames and covers comply with European standard PN-EN 124-4:2015-07, ensuring quality, safety, and reliability in infrastructure applications.
