Unit Load Spiral Conveyors
Save space and increase throughput.
The Ryson Spiral Conveyors need less floor space than conventional conveyors and are faster and more reliable than any elevator or lift.
The Ryson Unit Load Spiral Conveyors can convey cartons, cases, trays, totes and all sorts of packaged goods up or down in a continuous flow. Central to our design is the Ryson proprietary slat-style belts designed with rolling friction without any sliding movements or wear strips. This facillitates a small footprint, high speed, low noise, low maintenance and a long life. Ryson Spirals are available in powder coated carbon steel, stainless steel, hybrid and freezer versions.

The spiral conveyor diameter is determined by the size of the loads (length, width and height) to be handled. A broad range of sizes makes the Ryson Spiral Conveyors to be viable in the manufacturing, packaging, bottling, order picking, distribution, and warehousing operations of most industries.
Spiral Conveyor Modular Design:
An innovative modular design allows Ryson to customize with ease and modify in the field to accommodate emerging needs. All spirals are made to order and are available in 4 basic configurations ( A, B, C and D), accommodating most requirements relating to the location of the in and out feed tangents. All configurations can operate up or down in a clockwise or counterclockwise rotation.
The position and length of the infeed-tangent on up spirals and the outfeed-tangent on down spirals can be customized to meet specific layout requirements. This is possible for all standard configurations. The following depict samples of common customizations:
- C-EX configuration matches the centerline of the top and bottom conveyor centerlines. Centerline offsets can also be accommodated.
- B-MA is an example of modified in or outfeed angle. The modified angle is normally 45 or 30 degrees, but other angles can be provided.
- A-EX show extended in or outfeed tangents which can be straight or curved and can accommodate centerline off-sets.
Proprietary Slat Belt Arrangement:
This innovative arrangement enables a low friction operation for the spiral conveyor. The slats are supported by precision steel roller bearings which ride on a polyurethane surface. This arrangement effectively takes up the side forces created by a tight radius and at the same time increases the load carrying capacity of the chain up to 75 lbs. per linear foot. This enables the spiral conveyors to start and stop fully loaded and facilitates high speed, low noise and long life.
The slats are made of a fiberglass reinforced nylon composite and are available in widths of 8″, 12″, 16″, 20″, 26″ and 30″. The slats can also be furnished with friction inserts when additional grip is required.

Controls and Integration:
Most of our Spiral Conveyors are shipped without controls because they normally integrate with an overall conveyor control system. Our spirals always include an inverter duty gear motor and two proximity sensors, one for the automatic chain tensioner and one for the overload protection device. We also offer a number of controls and pre-wiring options.
A Variable Frequency Drive (VFD) is required for proper operation of the spirals. All Ryson Spirals are thoroughly shop tested prior to shipment, but depend on proper integration with the overall conveyor system for optimum performance. Read about our Integration instructions.
