Montague Cold Storage has been in business for over sixty years. Family owned, Montague’s started life as a supplier of fruit and flowers before becoming one of the largest cold store operators in the states of Victoria and Tasmania with over 140,000 pallet spaces available. Phase 1 of Montague’s new Truganina store was commissioned at the end of 2014 and has a capacity of 30,000 pallet spaces. I was delighted to be shown around the facility by the Facilities Director, Glenn Edwards.     At 20 metres wide the loading dock has ample space to make up loads.  There is also a demarkated walk way next to the loading bays, with pedestrian gates at each bay to prevent fork truck\pedestrian accidents                 A well protected pallet conveyor allows picked pallets to be shrink wrapped and then returned to the freezer to await dispatch. It can also shrink wrap incoming pallets and take them into the  freezer.                 The high speed doors for the conveyor in and out feeds have fans which prevent a build up of frozen condensation.                   Ammonia detector and alarm situated on the elevated pedestrian walkway                   Double leafed insulated and forklift proof doors have been used. Note the special replaceable tiles on both sides of the door in this heavy use area.                 Freezer door entry protection is substantial and far more than would be normally seen in South African stores.         LOADING DOCKS The loading docks at Truganina have been designed for maximum efficiency and in line with Health and Safety legislation. After entering the site through a special entrance, the trucks wait at a marshalling point until directed to a particular loading bay. Backing up to the loading bay is assisted by ground guides which make sure that the rear of the truck is correctly placed. Then the trailer’s rear protection bar is locked in position. Until the lock is in place, the internal loading bay door will not open nor can the dock leveller be activated. The lock prevents the truck from moving away from the loading dock with a forklift inside. The driver then enters vestibule of the loading dock through the door and opens the truck doors. The air seals activate to prevent the ingress of warm moist air, the dock leveller is put into position and the internal door opens. While waiting for the truck to be loaded/offloaded, the driver has access to bathroom facilities and a canteen. He is observed by the cold store staff as they must sign off that he is fit to drive the truck to its next destination. As his load is processed, the driver stands on an observation platform in the loading dock to check the pallets. When the doors are sealed and the paperwork completed, the lock is released and the truck leaves via a gate that only opens when the cold store staff have checked that everything is in order.                                                                                 FREEZER ROOMS The freezer rooms are constructed from PIR panels. The local fire authority required that the freezer ceilings be fitted with sprinklers. Had the cold store been placed on the other side of the road, it would have fallen under another fire authority making sprinklers unnecessary. Hitting a sprinkler head will not in itself activate the system. Excessive heat must also be picked up by sensors. The freezer rooms are equipped with double deep racking. Case picking is an important aspect of the business and takes place inside the freezer. Product is supplied to the pick faces via roller beds. Stackers are not allowed in lanes where case picking takes place. Racked picking bays have been made wider than normal to allow for better access to the cases. Space has been created underneath the roller beds to allow room for the picker’s feet. The racking is of high quality and well protected. The upper levels have guides to assist with placing the pallets.     Ceiling shot showing the sprinkler pipes.                     Pallet racking is 8 levels high with all pallets being 1200mms in the height. The Australian pallet base is 1165mms by 1165 mms and has slots into which the load beams fit. Cold store lights are operated by movement sensors and are LEDs.               Glenn Edwards, Montague’s Facilities Director, shows how the extra space in the picking bays assists the case picking process. Note the protective fencing above Glenn’s head.                   Pallet location information is on the rack frames. This particular frame spans a floor joint hence the larger slots and bolts in the load beam to allow for movement.                                     Goal posts and rack end protection are welded to plates cast in the floor. The welding is designed to fail before the plate is ripped out of the concrete.               MATERIALS HANDLING EQUIPMENT Stackers with extendable forks are used to place and retrieve pallets in the double deep racking. Their front wheels must be able to go under the bottom level of pallets. Cases are picked via man on pallet movers. Stand on forklifts are used in the trucks. The stackers have no heated cabs and the fork lifts/pallet movers are all of the stand-up variety. High quality freezer clothing is worn by all cold store employees. The battery bay is well thought
