C-Type Coil Hook
Product Overview
The C-Type coil hook is a purpose-built C hook for coil lifting and overhead coil hooks applications. Designed for safe, stable horizontal coil handling, our coil lifting hooks feature a low-carbon steel lifting body with internal stiffening ribs and embedded reinforced lifting lugs. CNC cutting ensures dimensional accuracy across models, while multi-layer anti-corrosion treatment and optional bolt-on wear plates deliver long service life in harsh environments. Custom configurations available up to 40 tonnes.
Construction & Manufacturing Details
Materials & Structure
Lifting body: low‑carbon steel — selected for toughness and suitability for high-frequency lifting operations.
Internal reinforcement: dense stiffening ribs to resist deformation.
Lifting lugs: embedded, reinforced, integrated with the lifting body to ensure stable load transfer.
Process & Protection
Dimensional control: CNC cutting ensures precision for length, opening and wall thickness.
Surface treatment: multi-layer anti-corrosion finish as standard; optional hot-dip galvanizing, epoxy primer systems or specialized coatings available on request.
Wear protection: optional bolt-on replaceable wear plates on contact surfaces to extend service life.

Selection Guide — How to Choose the Right Coil Hook
By Load
Light coils (< 10 t): plate-type or structural C hooks are usually sufficient.
Heavy coils (> 20 t): box-type C hooks are recommended for greater bending and torsional resistance.
By Environment
High-temperature operations: select box-type hooks made from heat-resistant alloy steels.
High-abrasion or high-wear scenarios: add bolt-on replaceable wear plates.
Precision handling: pair hooks with mechanical stops and electrically interlocked anti-fall devices.
Installation, Inspection & Maintenance
Before first use: Verify the hook model, rated capacity, and dimensions match the coil and lifting equipment. Inspect for any visible deformation, cracks or loose fasteners.
Daily/Shift checks: Inspect lifting lugs, counterweight connections and wear plates; look for excessive wear, corrosion or deformation.
Periodic maintenance: Maintain anti-corrosion coatings; replace wear plates when worn beyond the recommended limit. Keep inspection records and test certificates with each unit.
Load testing: Perform factory or on-site load tests per customer or regulatory requirements; provide test reports upon delivery.
Safety Information
Never allow personnel to stand under a suspended load. Keep the area beneath the lift clear of all personnel.
Do not exceed the rated capacity. Overloading may cause catastrophic failure.
Replace damaged or deformed hooks immediately. Do not attempt repairs that alter the original structure without factory approval.
Use correct rigging practices and confirm the crane/hook alignment before lifting.
Faqs
Q : What is a C-Type coil hook used for?
A — A C-Type coil hook is a lifting device designed for horizontal handling of coiled materials such as steel or aluminium coils. It engages the coil safely and transfers load to crane rigging for movement, stacking or loading operations.
Q : Can the hook be customized to fit non-standard coil widths or inner diameters?
A — Yes. We offer custom-sizing services. Provide your coil width, inner diameter, and rated load and we will propose an optimized design.
Q: How do I request a custom design or CAD file?
A：Contact our sales team with the coil dimensions (width, inner diameter), required rated capacity and any special environment or regulatory requirements. We will provide CAD (STEP) files and a quotation.
