A new concept.
The Ryson Spiral Conveyors represent a new concept in vertical conveying, based on a proprietary low friction chain slat arrangement. The Ryson Spirals are attractive because they have a higher throughput capacity, require less space, generate less noise, consume less energy, cost less to install, need less maintenance and have a longer life compared to conventional methods. The spiral conveyors are also known as spiral or case lifts, spiral elevators, and spiral lowerators.

High Throughput
The spirals convey loads up or down in a continuous flow, thereby facilitating high throughput. The standard load capacity is 75 pounds per linear foot of conveyor for speeds up to 200 feet per minute.

Small Footprint
The Ryson Spiral Conveyors have the smallest footprint available and therefore provide substantial space savings compared to conventional methods. Several standard sizes are available and the outside diameter varies depending on the size of loads to be handled.

One Drive
The Ryson Spiral Conveyors need only one drive motor, even for units several stories tall. This equals to substantial savings in controls and systems integrations.

Proprietary Chain Slat Arrangement
An innovative chain slat arrangement facilitates low friction operation. The conveyor slats are supported by precision steel roller bearings which ride on a polyurethane guide surface. The guides are embedded in an extruded aluminum profile which in turn supports the spiral track. This arrangement efficiently takes up the side forces caused by a tight radius and at the same time increases the load carrying capacity of the chain. This arrangement also facilitates smooth operation, high speed, low noise level and long life.

Low Maintenance
The Ryson Spiral Conveyors are designed for low maintenance and long life. Only high quality components requiring little maintenance are used throughout. The roller bearings are sealed and lubricated for life. The chain is of a heavy-duty chrome plated construction. The slats and carriers need no maintenance and can easily be replaced as single components without the use of special tools.

Overlapping Slats
The overlapping slats provide a smooth efficient conveying surface suitable for a wide variety of load types and sizes. The slats are made of a fiberglass reinforced Polyamide and are available in widths of 8", 12", 16", 20" and 26". The slats can also be furnished with friction inserts to accommodate slick products such as plastic totes or frozen items.

Built-in Protection
All spirals are equipped with an automatic chain tensioning device and built-in overload protection. The chain tensioning device is spring operated and a proximity sensor is sensing the correct operating position of the device. The overload protection is accomplished by mounting the drive motor on an adjustable torque arm arrangement which will pivot during an overload condition. This motion will be detected by a proximity sensor which in turn will cause the motor to stop.
