Height Restrictions
When loading a delivery vehicle onto pallets, consideration needs to be given to the clearance required when lifting the pallet at the unloading point. There may also be height restrictions at the goods-in area or warehouse at the delivery point or at another point further down the distribution chain.
Air Circulation
If the goods are being refrigerated, some clearance may also be necessary to allow air circulation around the load. Air circulation may also be important for some non-refrigerated goods.
