The Ryson Unit Load 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 – or case spiral – 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 facilitates 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.

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.

Ryson Spiral Conveyors have many unique features that make them ideal Vertical Conveying Solutions. Many of our features are designed to save money in the long term, essentially lowering your total cost of ownership.

Design Flexibility: Our unique design offers flexibility of configuration. It also adds the ability to field modify to accommodate changing future needs at a fraction of the cost of a new conveyor.

Overlapping slats provide a smooth and efficient conveying surface, ensuring gentle product handling and suitable for all types of conveyable items. Our efficient rolling friction chain-slat design only needs a single drive, resulting in substantial savings in energy, controls and systems integration.

Our innovative chain-slat design enables a low friction operation without any sliding movements or wear-strips. This allows the Spiral to stop and start fully loaded.

Our efficient rolling friction chain-slat design only needs a single drive, resulting in substantial savings in energy, controls and systems integration.

Most Spirals ship in one piece and leave our factory pre-assembled and pre-tested. Installation is generally an efficient process and reduces time for implantation and integration.

Our Spirals and components are designed for reliability, low maintenance and long life. They have an impressive up-time record reducing the total cost of ownership.

The proprietary low friction chain slat belt allow Ryson Spiral Conveyors to operate within a small footprint, saving valuable floor space. See the chart below for specific dimensions on our most popular models.


Our innovative modular design allows Ryson to customize any spiral conveyor with ease and can also be economically modified in the field to accommodate changing needs.  All spiral conveyors are made to order and  can operate up or down in a clockwise or counterclockwise rotation and can optionally be reversible.  The position and length of the in feed tangent on up spirals and out feed tangent on down spirals can be customized to meet specific layout requirements. 

Only one drive motor is required, resulting in substantial savings in energy, controls and systems integration.

All Ryson Spiral Conveyors are made to order and comes in a wide range of sizes and configurations.

All Ryson Spiral Conveyors are equipped with an automatic chain tensioning device and built-in overload protection as a standard. This helps save both the Spiral and the product it is conveying.

All Ryson Spirals are designed with a horizontal section at the in and outfeed. This assures a safe and reliable transition between the spiral and adjoining conveyors without product damage and undue wear.

Our proprietary chain slat belt assures a low noise operation, less than 75 db in most cases.

The Spiral Conveyors convey loads up or down in a continuous flow, facilitating high throughput.  Many spirals can operate at speeds in excess of 200 FPM and are optionally reversible.

 

Ryson Spirals are powder coated carbon steel with choice of any standard RAL color. They are also available in hybrid versions suitable for wet environments or stainless steel versions for washdown applications.

Ryson Spirals are designed for low maintenance and long life.  Only high quality components are used throughout.  All bearings are sealed for life and need no further lubrication.  The chain is of heavy duty nickel plated construction and needs only infrequent lubrication.  The slats are made of a nylon composite, need no maintenance and can easily be replaced as single components without the use of special tools. Ryson has a full staff of factory trained service technicians ready to assist. All of our service techs are PMMI Certified Trainers. All of these factors contribute to Ryson’s low total cost of ownership.
