This is the pre-selecting part:
Select any box, bonus points if you select one earlier in line or you find two for the same vehicle.
Don't stack or keep it to an absolute minimum and stack/tote the smaller objects first while always loading the larger ones.
Always load things that are on the floor first.
Now for the loading part, the one Literally no supervisor and half of preload do not know how to do neatly or efficiently:
Part 1: Build a layer of medium-or-larger boxes loaded depth>height>width, unless you are under the gliding door installation (shelf 5000 and 7000) where you can opt to load depth>width>height.
Part 2: Anything long that sticks out more than 1/2" from a shelf goes on the floor, return to shelf if space allows at the end of the day. You can hit yourself and impede quick movement by leaving boxes too far off of a shelf.
Part 3: Subsequent thinner/smaller boxes: slide behind or load on top, snug against the wall. keep doing d>h>w or d>w>h no matter what it is. Try loading all the way to the tippy top as long as the HIN is reasonably in-order and most, if not all, boxes can be select lower-hin-first.
Part 4: Subsequent wider boxes: pull the older, thinner box off the shelf then do part 1/part 3. This step is important to build tight loads, as wider boxes loaded on top of a few thinner boxes will most-likely become lopsided or overhang, which wastes shelf space.
Part 6: If the shelf space is too thin for the next box, try a bit of step 3, then try to make space by sticking your hand in ther and sliding everything forward. If you still do not have enough space, begin placing the largest boxes, especially a bulk stop of large boxes, on the floor.
Part 7: Just a quick reminder that part 3 includes all small boxes, virtually all bags (box bags, solid object bags, pill bags), and envelopes. Do not dump smalls into the load randomly or you will waste space, lead things to fall over in motion, and make finding them difficult. t-shirt bags (ones that have no structure whatsoever) go on top of or behind everything else.
A quick note on package facing and writing
You can save time by orienting the package in your hand and writing on it as you walk into the PC. Keep in mind the orientation is almost always d>h>w so your hands/palm will be holding the long-thin side and if you are palming the package, you will write on the side with the smallest surface area.
If you walk in with a stack, keep every barcode facing up so you can drop the whole stack, scan and load without fumbling with each piece.
Let things drop off the belt, who cares.
at my center. If it’s loaded like crap it doesn’t matter if the driver wants to leave, he still has to pull over to sort it out.
