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.

Bucket Elevators with
The Ryson Bucket Elevators are designed to withstand many years of heavy duty operations. Elevators with multiple outlets have selective bucket tipping capabilities created by an air actuated tipping ramp. The last tipping ramp stays in a fixed position to assure that all buckets are emptied.
The chain is a 2″ roller chain with hollow pin shaft and 1 1/8″ diameter rollers. The conveying surface is made of polyurethane for smooth and quiet operation. The buckets are made of a food grade reinforced polycarbonate molded in one piece that can handle temperatures from -5 to 215 degrees Fahrenheit.
Anti-static and stainless steel buckets are optional. The bucket elevators allow for controlled feeds at one or more locations and can easily interface with various types of feeding devices.
