Plastic Flat Top Chains for Spiral Conveyors

Plastic flat top chains for spiral conveyors are a highly specialized solution engineered to handle the unique demands of vertical elevation, accumulation, and buffering in a compact footprint. Designed for reliability and smooth performance, these chains are the backbone of spiral systems used in food processing, beverage production, and large-scale packaging operations. Our portfolio, featuring the 1873, 1875, and 3873 series, offers robust, high-performance options for nearly any spiral conveying application.
Unlike standard side-flexing chains, spiral conveyor chains are built to withstand the continuous, high-tension environment of a helical path. They feature a heavy-duty chassis, a tight turning radius, and a stable, flat surface that ensures products remain upright and secure as they move between elevations.

Key Advantages of Spiral Conveyor Chains

Our plastic flat top chains for spiral conveyors are designed to maximize throughput, save valuable floor space, and ensure long-term operational reliability.

High-Strength, Heavy-Duty Construction

Spiral conveyors place significant tensile load on the chain. Our spiral series, such as the 3873, are built with a robust frame and high-strength pins (available in stainless steel) to handle tensile loads up to 4,000 N. This ensures long life and reliable performance even in demanding, 24/7 operations.

Optimized for Vertical and Helical Movement

These chains are engineered with a specific back-flex radius (collapsing radius) that allows them to travel smoothly around the tight curves of a spiral drum. The design ensures the chain remains flat and stable, preventing product tipping or jamming during vertical transport.

Anti-Skid and High-Grip Surface Options

For applications involving elevation changes or products that are prone to slipping, we offer chains with integrated anti-skid surfaces. The 1873 and 3873 series are available with co-molded rubber or TPU top surfaces that provide exceptional grip, ensuring products stay in place even on inclines or at high speeds.

Space-Saving Vertical Conveying

A key benefit of spiral conveyors is their ability to move products vertically within a very small footprint. Our chains enable the design of tall, compact spiral systems for applications like accumulation, buffering, cooling, or freezing, freeing up valuable floor space for other processes.

Applications for Spiral Conveyor Systems

Plastic flat top chains for spiral conveyors are essential in systems designed for:
  • Vertical Elevation/De-elevation: Moving products between different floors or production levels.
  • Accumulation and Buffering: Providing a first-in, first-out (FIFO) buffer between upstream and downstream processes to absorb micro-stops and improve line efficiency.
  • Cooling and Proofing: Allowing products like baked goods to cool or dough to rise over a long period in a compact, climate-controlled space.
  • Freezing: Transporting products through a spiral freezer for rapid, individual quick freezing (IQF).

What is a spiral conveyor chain?

A spiral conveyor chain is a specialized type of plastic flat top chain designed specifically for helical (spiral ) conveyor systems. These chains are engineered to handle the unique demands of vertical elevation, accumulation, and buffering in a compact footprint. They feature a heavy-duty construction, tight turning radius, and stable flat surface to ensure products remain upright and secure during vertical transport.

 What are the main advantages of spiral conveyors?

Spiral conveyors offer significant space savings by moving products vertically within a small footprint. They are ideal for applications requiring accumulation, buffering, cooling, proofing, or freezing. By eliminating the need for multiple horizontal conveyors and transfer points, spiral systems simplify machine design, reduce costs, and improve overall line efficiency.
What is the difference between the 1873, 1875, and 3873 series?

El 1873 series is a general-purpose spiral chain available with or without bearings and optional anti-skid surfaces. The 1875 series features a split-chain design for ultra-wide spiral conveyors. The 3873 series is our heavy-duty flagship, offering the highest tensile strength (up to 4,000 N) and multiple anti-skid options, making it ideal for the most demanding spiral applications.
What is an anti-skid surface, and when is it needed?

An anti-skid surface is a co-molded rubber or TPU top layer that provides exceptional grip. It is essential for applications involving elevation changes, high-speed operation, or products prone to slipping. Anti-skid chains ensure products stay in place even on inclines, preventing jams and improving overall system reliability.

Can spiral conveyor chains handle heavy loads?

Yes. Our spiral series, particularly the 3873, are designed for heavy-duty applications with tensile loads up to 4,000 N. They feature robust frames and high-strength pins (available in stainless steel) to ensure long life and reliable performance in demanding, 24/7 operations

What is the typical pitch for spiral conveyor chains?

All our spiral conveyor chains feature a standard 38.1mm (1.5-inch) pitch. This pitch is optimized for the balance between strength, flexibility, and compact design required in spiral systems.

What materials are used in spiral conveyor chains?

The chain body is typically manufactured from Acetal (POM) for excellent strength and low friction. Anti-skid surfaces are co-molded from Goma o TPU for high-grip applications. Pins are available in engineered plastic or Acero inoxidable for maximum strength and corrosion resistance.

What temperature range can spiral conveyor chains handle?

Our spiral chains typically operate in a temperature range of -20°C to +80°C, making them suitable for a wide range of environments, including cooling and ambient-temperature applications. For freezing applications, special materials may be required.

How do I choose the right width for my spiral conveyor chain?

The width should be selected based on your product size and the required stability. Wider chains provide more surface area and better support for larger or unstable products. Our engineering team can help you analyze your product characteristics and recommend the optimal width for your spiral system.

How do I maintain spiral conveyor chains?

Regular inspection is key. Check for signs of wear, such as cracks, elongation, or damage to the anti-skid surface. Clean the chains regularly to prevent buildup of debris. Ensure proper chain tension and alignment. Lubrication is generally not required, but in some high-load applications, a light food-grade lubricant may be beneficial.
