Welded Steel Chains with Attachments

Precision Welded Steel Chains with Custom Attachments

Key Types & Attachments

• Chain Types

• WH: All components through-hardened for general heavy-duty conveying.

• WHX: Through-hardened + induction-hardened pins for extreme wear.

• WR: Through-hardened rivets only, cost-effective for light-to-medium loads.

• Offset Sidebar: For tight turns; Straight Sidebar: For high-tension lines.

• Common Attachments

• C1/C3/C4: Full-length carrier plates for bulk material retention.

• W1/W2: Welded scrapers/swing plates for drag applications.

• A1/A2: Extended pins for flight mounting; K1/K2: Offset lugs for side loading.

• RR: Reverse barrels for bidirectional travel.

Critical Features

1. Strength & Durability: Heat-treated alloy steel, welded construction, high impact resistance; rated for continuous heavy loads and abrasive environments.

2. Attachment Versatility: Custom welded attachments (scrapers, flights, paddles) for precise material handling; field-repairable with standard tools.

3. Standard Compliance: ANSI B29.18M/ISO 6971 ensures interchangeability; hard-face welding on sliding surfaces minimizes wear.

4. Temperature & Corrosion: Operating temp -20°C to +120°C; standard finish is oiled/black oxide; upgrade to zinc-plated or hot-dip galvanized for mild corrosion resistance.

Application Scenarios

• Primary: Logging, sawmills, pulp/paper, grain handling, mining aggregate, waste management.

• Secondary: Chip/sawdust conveyors, drag lines, bucket elevators, heavy-duty assembly lines.

• Limitations: Not for high-speed power transmission; avoid strong acids/alkalies (use stainless steel variants if needed).

Selection & Installation Guidelines

1. Load & Speed: Calculate static/dynamic loads, ensure safety factor ≥4; max speed ≤0.5 m/s for drag chains.

2. Attachment Match: Choose C-type for bulk, W-type for scrap, A-type for flights; confirm pitch/sprocket compatibility.

3. Sprocket & Tension: Use ANSI B29.18M sprockets (min 17 teeth); maintain 1–2% chain length tension for smooth operation.

4. Maintenance: Lubricate pins/bushings biweekly; inspect welds and attachments monthly for cracks/wear.
