Twin-Trak® Side-by-Side Conveyor ►

Unlimited Power for Limited Spaces

Richards-Wilcox Twin-Trak Conveyors combine power and free capability with a side-by-side track configuration. Twin-Trak offers the ideal medium- to high-capacity solution where limited overhead space is available for product storage and transportation.

Twin-Trak can be built from pre-existing Richards-Wilcox systems, such as Safe-Rail and Zig-Zag. Once a Safe-Rail monorail or a Zig-Zag chain conveyor system is in place, standard in-stock Richards-Wilcox parts can be added to create a Twin-Trak power & free conveyor system.


The Twin-Trak side-by-side conveyor system builds on the foundation of our monorail conveyor products. By combining elements of the single track Safe-Rail with aspects of the industry-standard Zig-Zag chain conveyor, the Twin-Trak system creates a space-saving dual-track solution. The system also features cutting-edge controls, easy switching, and impressive weight capacity.

The following is a list of standard Twin-Trak conveyor system features:

  • Eleven Standard Zig-Zag Components

Twin-Trak uses the same standard components as Richards-Wilcox chain conveyor systems.

  • Eight Standard Safe-Rail Components

Twin-Trak uses the same standard components as Richards-Wilcox standard monorails.

  • Control Systems

Twin-Trak is available with a variety of state-of-the-art control components, ranging from simple PLC-based controls to complex PC-based routing and tracking systems.

  • Capacities

Twin-Trak combines a 3/16″ plate steel load track with a carrier range of 125 to 1,000 lbs for maximum flexibility.

  • Switching

Twin-Trak provides switching into and out of the main line of travel in greater frequency (at closer load centers) than other power and free designs.


In addition to its high weight capacity, durability, and convenient modular design, the Twin-Trak conveyor system provides a number of benefits that can drastically improve existing processes. Whether you plan to utilize a Twin-Trak conveyor for a material handling system or as part of a conveyor assembly line, this dual-track solution can provide a variety of industrial advantages.

The following are just a few of the unique benefits of the Twin-Trak power and free conveyor system:

  • Optimizes Low Headroom

Because of its side-by-side configuration, Twin-Trak can be installed in facilities having insufficient headroom for other power and free equipment.

  • Increases Throughput

With controlled accumulation, Twin-Trak eliminates the typical wait time associated with storage banks.

  • Utilizes Space Efficiently

Twin-Trak minimizes floor space requirements by storing work-in-process overhead, calling it down in the quantity and order needed at each operation.

  • Controls Production Rates

Twin-Trak optimizes production by ensuring that the right parts arrive at the correct operation in a continuous flow, especially when rates of production differ between operations.

  • Maintains Quality

Twin-Trak eliminates product rehandling and manual transporting by integrating finishing and assembly processes into one material handling system.

  • Boosts Efficiency

Twin-Trak maintains a traveling record of a work-in-process, logging information on where a product has been and where defects may have occurred.


The Twin-Trak overhead conveyor is a flexible, multi-use system that can improve the efficiency of a variety of industrial processes. Whether you plan to use the Twin-Trak system in a distribution center, auto shop, or manufacturing plant, this compact overhead solution can be a huge asset to your business.

The following are a few of the possible applications of the Twin-Trak conveyor system:

  • Paint Finishing Systems
  • Investment Cast Mold Delivery
  • Extrusion Finishing
  • Progressive Assembly
  • WIP Buffer Storage
  • Comber Lap Delivery
  • Sliver Can Delivery
  • Aerospace Refinishing
  • Fiber Delivery
