2 Objective  Comprehend how to use shoring to prevent exceeding any aircraft limitations Comprendre comment utiliser le planche de protection pour éviter d’aller au delà des limites de l’avion

3 Overview Apercu  General  Load Spreading Etalage du chargement  Shoring Categories Planche de protection

4 General Purpose  Provides protection Aide de protéger Aide de protéger  Performance

5 Load Spreading and Weight Distribution Etalage du chargement et Répartition de poids  Load spreading is a physical process that distributes a concentrated weight over a larger area L’etalage du chargement est un processus physique qui repartit sur une plus grande surface un poids concentre  Weight exerts a certain amount of pressure determined by its supporting contact area Le poids exerce une certain quantité de pression déterminée par sa surface de contact déterminée par sa surface de contact

6 Load Spreading Contact Area Surface de contact  The contact area is increased at a 45 degree angle from the upper surface of the shoring to the cargo floor La surface de contact est haussée a un angle de 45 degrés a partir de la surface supérieure du rivage au plancher du cargo

7 Load Spreading Contact Area  The increased contact area decreases the pressure on the floor La zone de contact élevée diminue la pression au sol  Shoring will only increase the area of contact  Shoring does not increase floor limitations Planche de protection haussera seulement la zone (surface) de contact—il n’augment pas les limitations du sol

8 Shoring Categories Catégories de Planche de protection Rolling Shoring  Protects floors and ramps Protégé les planchers et les rampes  Generally not required for most vehicles Généralement pas exige pour la plupart des véhicules

9 Shoring Categories Rolling Shoring  Protects the floor from vehicles with cleats, studs, or other gripping devices Protégé le plancher contre de matériaux rigoureux Minimum thickness of shoring is ¾ inch (1.8cm)

10  If you need rolling shoring rolling shoring you will need you will need parking shoring parking shoring Shoring Categories Parking Shoring

11 Shoring Categories Parking Shoring  All trailers with a tongue that could rest on the aircraft floor must be shipped with parking shoring Toutes les remorques qui a un bout qui reste au sol doit avoir une planche de protection quand ils sont stationné

12 Shoring Categories Parking Shoring  Pneumatic tires do not normally require parking shoring Généralement les pneumatiques n’ont pas besoin du planche du protection

13 Shoring Categories Parking Shoring  Always use whenever there are sharp edges or protrusions that could damage the aluminum surface of a 463L pallets

14 Shoring Categories Sleeper Shoring  Use under frames or axles of vehicles that weigh over 20,000 lbs (9091 kg) and have soft, low pressure, balloon- type, off road tires

15 Floor limitations vary according to aircraft  Floor limitations vary according to aircraft Les limitations du plancher varient selon l’avion Les limitations du plancher varient selon l’avion Shoring Categories Sleeper Shoring

16 Shoring Categories Approach Shoring  Use approach shoring to decrease the approach angle of aircraft loading ramps Utiliser le “approach shoring” pour réduire l’angle de la rampe de chargement  Some items of cargo may strike the aircraft or ground during loading/offloading operations

17  There is no standard method to calculate how much Approach Shoring is required  These are pieces of equipment that normally require Approach Shoring:  Helicopters  All 40K loaders  Long vehicles Shoring Categories Approach Shoring
