Product Description

B125 Ductile Cast Iron Manhole Cover EN124 Round 675 X 675 D400 Cover

Circlip Lock Ductile Cast Iron EN124 D400 B125 Round Manhole Cover

Design Features

The spring manhole cover features a specialized spring structure designed to enhance stability, security, and safety. Its mechanical locking system with elastic buffering prevents bouncing, displacement, or theft caused by vehicle impact or external forces.

This innovative design addresses common issues with traditional manhole covers, making it ideal for high-traffic areas. The optimized materials, structure, and standards make it a crucial safety component in modern urban infrastructure.

Structure and Principle

Circlip Device: Composed of slots, blocks, and telescopic springs that create a mechanical lock when closed, preventing loosening or bouncing.
Double-layer spring design: Enhances pressure resistance and stability for high-load areas like motor vehicle lanes.
Anti-bounce function: Tensioning structure with springs ensures fixed positioning under force, reducing vibration and noise.

Material and Performance

Ductile Iron Construction: High strength, corrosion resistance, and toughness with load capacity exceeding 80 tons (D400 level), suitable for urban main roads.
Anti-slip & Anti-theft: Surface features anti-slip patterns combined with lock structure to prevent theft and accidental opening.

Maintenance and Innovation

Easy maintenance: Simplified installation and removal process for daily maintenance.
Process improvement: Spring displacement adjustments (e.g., 1 cm offset) solve loosening issues caused by aging, significantly reducing maintenance costs.
