Type: forging type forging type

Material: 23mn \ 20mn \ 20mn vanadium

Features: Light, flexible, firm; Tooth shape design is unique, tooth shape with accurate, convenient disassembly and assembly. Connecting ring chains for mining purposes. When used, it can be installed horizontally or vertically.

The spiral tooth ring is a hollow positive cylinder, and the two rotating rings form a large convex inlay part from the -pole - end, and the -end bends the ring ring and then circles around the flat and straight section for positioning. The two rotating rings can be placed in the opening at both ends of the body by the convex inlay part, and then consolidated into the - body by rolling and closing the hinge. Through the applicable new model, the opening at both ends of the body can achieve horizontal equal closure effect, so as to enhance the binding tension strength And good flexibility of rotation effect.

 

Purpose: Connecting ring chain for mining. When used, it can be installed horizontally or vertically.

FAQ:

1. What is a Mining Link Chain Connected Ring?
This product, commonly known as a Detachable Link Chain, Surveyor's Chain, or Connecting Link Chain, is a series of identical, interlocking steel links designed for easy assembly and disassembly. It serves as a flexible, high-strength connection for towing, lifting, securing, and demarcation in mining, construction, surveying, and marine applications.

2. What are its primary applications in mining and industry?
It is a versatile tool used for:

Mine Surveying & Demarcation: Measuring distances and marking boundaries underground or on the surface.

Material Towing & Dragging: Connecting to buckets, scoops, or machinery for pulling loads.

Safety Barriers & Securing: Creating temporary guardrails or securing equipment on transport.

General Rigging & Lashing: For bundling pipes, timber, or other materials.

Marine & Dock Use: As mooring chains or for securing cargo.

3. What materials and specifications are used?
We manufacture chains from high-grade materials for strength and durability:

Material: High-Tensile Carbon Steel (Grades Q235, Q345, or equivalent). Alloy Steel (Grade 80/100) is available for higher strength requirements.

Surface Treatment: Hot-Dip Galvanized (HDG) is standard for maximum corrosion resistance. Self-colored (black), electro-galvanized, or powder-coated finishes are also available.

Common Sizes: Chain link diameter (Ø) typically ranges from 5mm (3/16") to 20mm (3/4").

Common Lengths: Sold in standard rolls of 30 meters (100 ft) or custom-cut lengths.

4. How is the Working Load Limit (WLL) determined?
The WLL is the maximum safe load the chain can handle in straight tension. It depends on:

Link Diameter (Ø): The single most important factor.

Material Grade (e.g., Grade 70 vs. Grade 100).

Manufacturing Standard.
We provide detailed WLL charts for each chain size and grade. A safety factor of 4:1 (Minimum Breaking Load / WLL) is standard.

5. How do I connect and disconnect the links?
The design allows for manual, tool-free connection:

To Connect: Slip the open end of one link into the closed end of another and twist it 90 degrees to lock it in place.

To Disconnect: Twist the link 90 degrees back and slide it out.
This feature makes it incredibly versatile for creating custom-length assemblies.

6. What is the difference between your chain and a welded chain?
Detachable Link Chain (Ours): Links are not welded closed. They can be connected and disconnected by hand, offering flexibility. Ideal for temporary, adjustable, or reconfigurable setups.

Welded Chain (e.g., Proof Coil Chain): Each link is welded shut. It is permanent and stronger for its size but cannot be reconfigured without cutting and re-welding. Used for permanent hoisting, slings, etc.
Our chain is for applications where adjustability and reusability are key.

7. Can you supply matching accessories?
Yes. We provide a complete system:

Connecting Hooks (Grab Hooks, Slip Hooks, Eye Hooks).

Turnbuckles for tensioning.

Repair Links & Shackles.

Storage Reels for easy handling.

8. What is the temperature and chemical resistance of the galvanized coating?
Hot-Dip Galvanizing (HDG) provides excellent corrosion resistance in most industrial and outdoor environments. It is suitable for temperatures up to approximately 200°C (390°F). Prolonged exposure to strong acids or alkalis can degrade the coating.

9. Do you offer custom lengths and packaging?
Absolutely. We can provide:

Custom-cut lengths to your exact requirement.

Special packaging on reels, in coils, or in boxes.

Private labeling for large OEM orders.
