Hercules manhole covers

Hercules manhole covers are built for high-performance access in demanding road and infrastructure environments. Designed for Group 4, D400 installations*, Hercules delivers outstanding load-bearing strength, skid resistance and long-term reliability.

Made from heavy-duty ductile iron, Hercules eliminates the need for complex fabricated solutions. Each cover features a small, secure inspection window for safe, single-person visual checks, while an M16 blank bolt can be replaced with a threaded lifting eye for easy, level mechanical lifting.

The indexed double-triangular design ensures correct seating and lasting performance. Combining operator safety, durability and efficiency, Hercules manhole covers provide a proven, low-maintenance solution that delivers strength and value in one complete system.
