Roller Chain Equipped Bucket Elevators

Where a vertical lift is required, the most widely used equipment is the bucket elevator, consisting of buckets fitted to a chain or belt which passes over a driven roller or sprocket at the top end. Bucket elevators can handle a wide range of solids from heavy lumps to fine powders and are suitable for use with wet solids and slurries. 

Large steel roller conveyor chains that are used on bucket elevators or in otho- extrranely abrasive applications may be equipped with pressure-lubricating fittings on the rollCTs or pins (Figure 3-39).
