Take the books off the range from the bottom to the top, right to left. Trucks are always loaded from the top to the bottom. Loading goes faster than unloading, so if we are short a team member, the loader will work alone. Books move downward on the ranges. In a backward shift , unloaders start with the flagged book from the right end of the top shelf of the truck and put it on the bottom shelf, at the right end.
Books move upward on the ranges.
These folks ferry the trucks between the loading and unloading sites. Because we will have over 10 shift teams working at a time, take the route you are shown. Use the elevator you are told to. Your book trucks are color coded, as are your loaders and unloaders. Be sure you take full trucks from the orange loaders to the orange unloaders, and empty trucks from the orange unloaders back to the orange loaders.
