Benefits of Hollow Pin Chain

Extremely flexible attachment combination: This is its outstanding advantage. Hollow pin chain allows a wide range of attachments (such as pusher plates, crossbars or special fixtures) to be simply and quickly inserted or removed at the required intervals. This makes the chain highly adaptable to the specific conveying or processing task.

Easy customization and reconfiguration: Adding or removing attachments without disconnecting the chain means that configurations can be changed quickly and easily. This is essential for production lines that process different products or require frequent adjustments to the conveyor layout.

Consistent attachment spacing: Since the attachments are inserted into the hollow pin chain, the center distance remains the same regardless of whether the chain is running straight or wrapped around a sprocket. This ensures precise spacing and synchronized movement of the transported items.

Simplified maintenance and repair: If attachments need to be replaced or adjusted, this can usually be done directly on the installed chain, significantly reducing downtime compared to chains where the attachments are permanently welded or require the removal of the chain links.

Load distribution (using crossbars): When crossbars pass through the hollow pins of two parallel chains, they can help distribute the load of a carrier evenly across both chains, enhancing stability and preventing twisting.

Lighter weight (in some designs): Hollow pins, while still strong, can allow for slightly lighter chain designs than equivalent solid pin chains, reducing inertia and power consumption in some applications.

Potential for internal lubrication: In some specialty models, hollow pins can be used for internal lubrication, although this is less common than when they are primarily used for attachments.

Applications of Hollow Pin Chain

1. Conveyor Systems (Main Applications)
Assembly Lines: Used to convey products through various assembly stages, often using custom fixtures or brackets fixed to the hollow pins to hold specific components.

Packaging Machinery: Used in production lines that require precise positioning, indexing, or transport of products through filling, sealing, labeling, or boxing stations, and use attachments designed for specific product shapes.

Food and Beverage Processing: Used in production lines that need to convey products to washing, cooking, cooling, or inspection stages. Stainless steel hollow pin chains are particularly common in these areas due to hygienic requirements.

Material Handling: General industrial conveyors that require flexibility in handling different sizes or types of products, or that need to push, pull, or transfer products.

Chip Conveyors: Used to move metal chips or other small debris in machining operations.

Lifting Conveyors (Bucket Elevators): Attach a bucket or tray to the chain to lift materials vertically.

2. Specialized processing equipment
Textile industry: In some machines, specific attachments are required to precisely guide or move fabrics or parts.

Agricultural processing: In some post-harvest processing lines, such as sorting or preparation lines for fruits and vegetables, customized transporters or chains are required.

Pharmaceutical manufacturing: In automated systems, delicate items or specific product forms require precise handling and cleaning operations.

3. Industrial automation
Indexing and positioning: In automated systems, precise intermittent motion is required and parts can be connected or removed at specific locations.

4. Chain hoist
This is a passenger or freight elevator with a series of open compartments that move in a continuous cycle, usually driven by a hollow pin chain connecting the compartments.
