Elevator System

T8140000094-UN-04MAR14

The elevator has a high clearance to minimize 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 170°.

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, 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 elevator chain and floor. The correct alignment is when the elevator chain just touches the wear strips as it leaves the sprocket, yet does not allow cane to get under the slats.

IMPORTANT: The elevator must be in the UP position before swinging and positioned directly behind the machine before lowering. Swinging elevator with cylinder not fully retracted may break cylinder rod and damage air louvers, basket, elevator support cable, and primary extractor housing.

Additional lowering is gained by raising the base cutter lift cylinders.
