Steel Mill Chains

When material handling equipment needs to move heavy loads through demanding industrial environments, the chain must provide dependable strength and consistent operation. Allied-Locke Industries manufactures steel mill chains for conveying, driving, and elevating applications where a high-strength, rollerless steel chain is required.

Allied-Locke’s welded mill chains are built for industrial material handling applications and can operate on the same sprockets as their cast chain counterparts. The product line includes multiple sizes and configurations to accommodate different load requirements and equipment designs.

Available options include:

• Welded steel construction for heavy-duty applications
• Rollerless designs for conveying, driving, and elevating
• Multiple chain sizes with different pitches, widths, and load capacities
• WHX Series options with induction-hardened pins or rivets
• Welded mill chain attachments for customized material handling requirements

The WHX Series uses induction-hardened pins or rivets to provide a harder bearing surface while maintaining ductility through the hardened core. Allied-Locke also offers custom-manufactured attachments for specific applications.

A properly matched chain is an important component of reliable steel mill conveyor equipment. Allied-Locke’s welded mill chains are recommended for conveyor applications as well as driving and elevating systems. Depending on the application, the chain’s direction of travel also matters. Conveyor installations should travel with the widest, open end first, while drive-chain applications should travel with the closed end or barrel first.

Allied-Locke supports applications including:

• Heavy-duty conveyors
• Forest products handling
• Grain handling
• Pulp and paper processing
• Sugar processing

With multiple chain sizes available, customers can select a configuration based on pitch, rivet diameter, side-bar width, barrel diameter, bearing length, and recommended working load.

As a systems manufacturer, Allied-Locke can also support applications that require chain attachments and compatible engineering-class sprockets. This helps customers address individual material-handling requirements rather than relying on a single standard configuration.

Allied-Locke’s welded mill chain catalog includes 18 chain options, with specifications provided for dimensions, working loads, ultimate strength, and weight. Product examples include:

• WH188 – 2.609-inch pitch and 2,850-lb recommended working load
• WH106 – 6.000-inch pitch and 7,200-lb recommended working load
• WH110 – 6.000-inch pitch and 7,875-lb recommended working load
• WH124 – 4.000-inch pitch and 7,200-lb recommended working load
• WH132HD – 6.050-inch pitch and 16,200-lb recommended working load
• WH155 – 6.050-inch pitch and 17,750-lb recommended working load
• WH159 – 6.125-inch pitch and 20,250-lb recommended working load

The WH124 is available with two sidebar bend profiles, while welded mill chain attachments can be custom manufactured to meet specific requirements.

Allied-Locke manufactures its welded mill chains in the USA. Its catalog notes that automated welding is used to help maintain consistent welds and barrel location. Carbon steel chains feature heat-treated pins, barrels, and sidebars, while stainless steel versions feature heat-treated barrels and pins. WHX options are also available with induction-hardened pins.

These manufacturing options give customers greater flexibility when specifying steel mill chains for demanding conveying and material-handling equipment.
