Elevator System

CQ280251-UN-28MAR08

The elevator system delivers the cane to a container system either to the rear, left or right hand side of the harvester. The perforated floor allows loose material to fall through, which is an additional feature of the cleaning process.

The elevator has a high clearance to minimize the damage caused by various cane containers that may come into contact with the underside. The height of the elevator is adjustable from the cab by two hydraulic cylinders supporting the elevator. The elevator swing table swings left and right a total of 180°.

The elevator is made up of twin lengths of roller type chain, connected by slats, which are bolted to the chain links. The conveyor is driven by orbital motors, mounted on both sides that are fully reversible to clear blockages.

To maintain correct chain tension, the drive motors are mounted in an adjuster box that allows chain adjustment. The chain on each side is driven by a sprocket, which is mounted directly to the drive motor shaft.

The idler chain alignment sprockets are adjustable to allow correct clearance between the elevator chain and floor. The correct alignment is when the elevator chain just touches the wearstrips as it leaves the sprocket, yet does not allow cane to get under the slats.

The elevator must be in the UP position before swinging or damage will result to the air louvers or basket and may damage the elevator support cable and primary extractor housing. Before lowering elevator make sure it is directly behind machine. Additional lowering is gained by raising the basecutter lift cylinders.

Replacement wear kits are available from John Deere dealerships.
