Abstract
An outlet gate assembly has upper and lower gate assemblies with independent drive mechanisms to open and close the gates. The drive mechanisms may be rack and pinion drives. The racks for the lower gate do not enter the gate cavity. The outlet gate assembly can be used for vacuum, gravity or pneumatic sled discharge. The vacuum openings are offset from the center plane of the discharge area to allow free flow of lading. The lower gate assembly includes surfaces that cover and protect the lowermost horizontal surfaces of the assembly when the lower gate assembly is closed. Thus, no separate mud plate is needed. The outlet gate assembly includes seals made of an ultra high molecular weight polymer.
