Product Pushers are used to push product perpendicularly from one conveyor traffic lane to another traveling in the same or the opposite direction, into or out of operator workstations or off of the conveyor system completely. They are used in conjunction with sensors and product stops for required traffic control and can incorporate either a rodless cylinder or a standard air cylinder. While pusher cylinders are normally mounted below the roller surface with the pusher operating in a space created by removing one or more roller shafts, they can also be mounted above the roller surface if the application so requires. Detailed technical information on the design and operation of this equipment appears in the appropriate Shuttleworth Engineering Specification available through all Shuttleworth offices.
