Product OverviewRecommended load ≤12T, capable of bearing medium work vehicles and maintenance tool vehicles, well-matching the daily operation and medium-load traffic needs of medium-large inspection wells;
The reinforced composite structure is not prone to cracking or deformation in inspection well environments, helping to improve the safety of medium-large maintenance operations.
SMC composite material has strong erosion resistance in humid, mild-corrosion medium-large inspection well environments, with an expected service life of over 18 years under proper use;
The anti-slip surface texture is not easy to accumulate dirt, making daily cleaning and maintenance relatively convenient.
Non-metallic material has no recycling value, which can alleviate the theft issue of traditional cast-iron medium-large round inspection covers to some extent;
Dual handle holes are adapted to the weight of medium-large size covers, allowing easy opening by one person with tools and improving inspection well maintenance efficiency.
Weighing about 30kg (vs. ~60kg for the same-sized cast-iron product), it is more convenient to install and carry, reducing labor input for medium-large cover operations.

Clean debris from the medium-large inspection well opening and confirm the size compatibility of the support frame with the opening;
After fixing the support frame, lay the cover smoothly aligned with the handle hole direction to ensure it fits the opening edge;
Conduct a light pressure test with a light work vehicle to confirm the cover’s fitting stability.
Clean surface stains monthly to maintain anti-slip texture effectiveness;
Inspect the firmness of handle holes and buckles quarterly (focused verification is recommended after the rainy season);
No additional anti-corrosion treatment is required. If damaged, send an email to jschangan111@gmail.com to contact the manufacturer for replacement coordination.
With over 10 years of experience in medium-large composite cover production, its round inspection covers have passed relevant certifications for municipal facility materials;
Supports customization of medium-large sizes, surface textures, and logos to meet different medium-large inspection well scenario needs;
Delivery service + on-site installation guidance are available for bulk orders, ensuring the operation efficiency of medium-large covers.
