The new Ryson Dual Track Spiral Conveyors are the ultimate in space savings.

Two tracks operate independently within one spiral structure. Both tracks can go up or down, and can optionally be reversible.

Only one drive motor is required for each track, resulting in substantial savings in energy, controls and systems integration. The dual spiral conveyors build on the already proven Ryson Spiral Technology and are designed for low maintenance and long life. Ryson Spiral Conveyors need less floor space than conventional conveyors and are faster and more reliable than any elevator or lift.

Custom configurations

The dual spirals are available in 4 basic standard configurations (A, B, C and D) and will accommodate 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 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.

Most of our spirals are shipped without controls because they are normally integrated into an overall conveyor control system. The spirals always include an inverter duty gear motor and two proximity sensors, one for the automatic chain tensioner and the other for the overload protection device.

A Variable Frequency Drive (VFD) is required for the proper operation of the spiral. Ryson offers several controls options including :
• Stand alone control panel with interface capabilities
• Prewired motor disconnect
• Proximity sensors prewired to a central junction box
• Prewired missing slat detection sensors.

Integration

All Ryson Spirals are shop tested prior to shipment, but optimal performance depends on proper integration with the overall conveyor system.
