Within one spiral structure, two tracks operate independently. These two tracks can be reversible, and can either go up or down. There are substantial savings in energy, controls and systems integration due to the fact that only one drive motor is necessary for each track. The dual spiral conveyors are manufactured for efficient long life and low maintenance, while also performing faster and more reliably than other elevators or lifts.


The dual spirals are available in 4 basic standard configurations 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 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 two tracks of the Dual Track Spiral Conveyors do not have to feed in and out of the spiral at the same elevations, and can be applied very effectively to multi-level order picking modules or similar applications. The outside track serves the first level and the inner track the second level.


Most spirals are shipped without controls because they are normally integrated into an overall conveyor control system. The spirals 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
