What exactly is Roll Handling with Cross Roll Forks? The customer below needed to handle both a roll with a shaft, as well as, just a shaft alone.
In order to use the same lifter for both operations, we supplied a lifter with a set of cross roll forks with v-blocks on the ends. We mounted side flowing rollers to the v-block on one side only for shaft only handling. These rollers run parallel to the forks, are set angular on the v-block, and are spaced to handle both 1.5” to 3” diameter shafts. In addition to the forks, we designed a removable center v-block arm with rollers to add support when transporting a shaft only, especially at transfer. Moving the arm up or down is a manual release via a hinge. This removable arm should be moved down to the same plane as the other arms when a shaft is to be loaded, and moved to the up position out of the way when handling a roll.
For handling the shafts only, they would be picked up from the machine at a side discharge elevation. The operator will move the lifter to the side of the machine and raise the forks to the corresponding discharge elevation. The operator would pull a shaft onto the lifter, and wheel the lifter to a roll sitting on the floor and align the shaft parallel with the roll core. The operator would then push the shaft from the lifter arms into the roll core via the rollers. Once inserted, the roll can be picked up.
At this step, the operator would position the lifter to straddle the roll and lower the forks to fit under the shaft. Moving the lifter forward the operator would drive the fork arms up under the shaft and drive the lift up to lift the roll by the shaft. The roll and shaft are then wheeled to the machine end. Here the roll and shaft will be raised, positioned over the loading blocks and then lowered onto the blocks until the roll is supported by the shaft. The operator will then lower the forks more to clear the shaft and then pull the lifter back leaving the roll on the stand.
For this application, the rolls were 26″ – 30″ diameter x 30″ wide x 300 pounds.
