In feeder, we often pick up from customers who load our trailers with their packages on pallets. At the hub, the loaded pallets are then broken down, inside the trailer, during the unloading process. Usually, conveyors extend into the trailer to retrieve the packages. Sometimes rollers are used.
The empty pallets are left in the trailer, along with any shrink wrap, bands, or tape the customer might have used to secure the packages to the pallet.
The next time the trailer is used, it is swept and the pallets are stacked in the front (or removed) by the next feeder driver to use the trailer. Some of the trailers are also cleaned by car washers.
