Assurance in extreme environments

Cargo

Designed to withstand extreme loads, Cargo F900 access covers ensure longevity and reliable performance in areas with heavy and intense vehicular traffic, such as the shipping, aviation and industrial sectors. They feature a powerful combination of strength, durability, and reliability that exceeds industry standards.

Cargo F900 manhole cover

Cargo is packed with features to ensure efficient and reliable durability, while including market-leading health and safety functionality that promotes safe handling processes.

The covers promote safe handling, safety keyways in the cover prevent lifting keys from becoming dislodged during the lifting procedure. M16 eye bolt points are also provided in the centre of each cover, for a safe mechanical lifting solution. The frame includes mechanical and safety keyway lifting points. All of these features significantly reduce risk to operatives during the handling and installation process.

Cargo offers our proven mortar-sympathetic frame arrangement, employing a textured flange, which utilises the mechanical properties of bedding mortar rather than just the adhesive characteristics. The flange edge is deliberately round-profiled, eliminating crack induction in the surrounding bedding materials. This all combines to ensure the longest operational life possible.

Key features of Cargo

Enlarged frame corners

Enlarged frame corners

Cargo's enlarged frame corners safely distribute and reduce load pressures exerted onto the foundation, increasing service life and reliability.

Mechanical lifting point

Mechanical lifting points

Mechanical lifting points are provided on both the frame and cover, increasing safe handling processes for site operatives.

Textured mortar engagement flange surface

Textured flange

Surface texturing above and below the flange enables better mortar engagement, reducing any lateral movement which could result in cracking.

Ideal for airports, shipping and industrial sectors

Designed for the extreme

Cargo manhole covers are specifically designed to endure the harsh and demanding conditions of high-impact environments. These covers are capable of supporting loads of up to an impressive 90 tonnes and have been tested to meet the F900 load class.

This level of capacity is vital for airports, where constant traffic from planes and service vehicles requires an access cover that can withstand the pressure without flinching. Similarly, docks, container terminals, and specialised industrial complexes can benefit from the resilience of these manhole covers. They provide safety while also preventing costly accidents or disruptions caused by heavy machinery and substantial material handling needs.

Our Cargo series is not just about creating strong covers, but rather about crafting solutions that can endure even the most challenging environments. We are committed to maintaining the safety and integrity of your infrastructure, regardless of the traffic it bears.

Unite(d) at Sunderland City Council

Sunderland City Council is responsible for the maintenance and repair of most roads and bridges in Sunderland. Like so many highway authorities, it had been receiving complaints from residents about noisy manhole covers. They immediately suggested Wrekin Products’ Unite manhole covers, which in addition to eliminating displacement under heavy traffic, as J T Dove explained, offer a range of other benefits.
