Logistics, Warehouse, Shipment Icons are missing

[roflc0pter]

Describe the requested icon(s)
Hey all! There are a few icons related to warehouse but I am missing a couple more related to logistics. What I wish to have are icons that represent actions and or objects of a warehouse activities such as

• A warehouse racks (like a ikea shopping center rack)
• a slot of a rack
• a dolly
• lifter
• stock-in
• stock-out
• stack of box
• slot with a box and a plus (to add a box to a slot)
• slot with a box and a minus (to remove a box from a slot)
• warehouse movements (change the place of a box)
• packing

References
I dont really have references to those, I would leave it up to the designer.
