1. 1

2. 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. 3 Overview Apercu  General  Load Spreading Etalage du chargement  Shoring Categories Planche de protection

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

5. 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. 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. 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. 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. 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. 10  If you need rolling shoring rolling shoring you will need you will need parking shoring parking shoring Shoring Categories Parking Shoring

11. 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. 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. 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. 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. 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. 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. 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
