As a professional manufacturer from Cangzhou Dean Safety & Special Tools Co., Ltd (established in 2001), we are proud to present our Rectangular Manhole Cover Hook made from premium ductile iron. With dimensions of 600x800mm and a hot dip galvanized surface, this lifting tool is engineered to safely handle loads up to 20 tons. Designed to meet the rigorous demands of municipal maintenance, construction, and industrial applications, our hook provides a reliable solution for removing heavy manhole covers without damage or risk. The rectangular shape ensures a secure grip on standard access covers, while the galvanized coating guarantees long-term corrosion resistance even in harsh environments.
Key Features & Technical Specifications:
- Material: Ductile iron (QT500-7) – high tensile strength and excellent impact toughness, preventing deformation under heavy loads.
- Size: 600mm × 800mm rectangular design – compatible with most standard manhole frames.
- Surface Treatment: Hot dip galvanized (zinc coating ≥85μm) – superior protection against rust, chemicals, and weather extremes.
- Load Capacity: Rated at 20 tons (200 kN) – verified through rigorous testing to ensure safe lifting without bending or breaking.
- Design: Integrated hook with rounded edges and anti-slip handle – reduces hand fatigue and improves operator safety.
- Color: Natural silver-gray galvanized finish – no paint peeling, UV resistant.
- Weight: Approximately 15-18 kg depending on exact casting tolerance – lightweight enough for manual handling yet robust for heavy-duty use.

Frequently Asked Questions (FAQ)
-
What is the main material of this manhole cover hook?
The hook is made of ductile iron (QT500-7), which provides high tensile strength and excellent resistance to impact and wear. It is much stronger than gray cast iron and less brittle. -
Can the hook be used for covers with a different shape or size?
This rectangular 600x800mm hook is designed for standard rectangular manhole covers. We also offer custom sizes; please contact us with your cover dimensions. -
What does the hot dip galvanized coating do?
The hot dip galvanizing process (minimum 85μm zinc layer) protects the iron from rust and corrosion, making the hook suitable for outdoor, underground, and marine environments. It also resists damage from road salts and chemicals. -
Is the 20-ton capacity a safe working load or the breaking load?
The 20-ton capacity is the safe working load limit (WLL). Our design incorporates a safety factor of at least 4:1, meaning the hook can withstand up to 80 tons before failure. -
How do I attach the hook to the manhole cover?
Simply insert the hook’s curved arms into the lifting holes or slots on the manhole cover. The rectangular shape ensures a secure fit. Then use the handle to lift the cover evenly. -
Does the hook come with any certification or test report?
Each batch is tested for load capacity and coating thickness. We can provide a material test certificate and load test report upon request. Note that specific third-party certifications (e.g., CE, ISO) are not included by default but can be arranged for an additional fee. -
What is the approximate weight of the hook?
The weight is around 15-18 kg, depending on exact casting tolerances. It is manageable for two workers but may be heavy for one person – we recommend using it with a lifting device for extreme loads. -
Can I get a sample before placing a bulk order?
Yes, we offer sample orders. The sample cost and shipping will be quoted based on your delivery address. Samples are usually ready within 15 working days after order confirmation.
For any further questions, please contact our sales team. We look forward to serving you with reliable manhole lifting tools.
