Heavy-Unit-Load Conveyor System Overview

Below is the overview of the conveyor system for P&O Cold Storage at Laverton II, as presented on a “Movement Controller” screen.

This warehouse features six stacker cranes, retrieving pallets from pallet stands rising from the conveyors. In the diagram below (from the MS-DOS version of the “Movement Controller”), the six cranes are shown at the infeed/outfeed positions, with the pallet stands at the outfeeds raised ready to accept pallets from the cranes, while those at the infeeds are lowered, expecting pallets from the conveyor system.

Just beyond the infeeds to the freezer and chiller conveyors are loaded-pallet detierers, beyond these are double alignment bars, followed by sizing stations and board checkers prior to the reject outfeeds.

Full status of the conveyor system, in the area centred on the cursor, will be displayed in response to the operator typing ‘Z’. Heavy-Unit-Load Conveyor Zoomed
