I work in the overnight freight buisness as a truck driver and work the warehouses. So let me give some insight on what's happening behind the scenes.
First things first it is way more difficult to find people who want to work warehouse especially overnight than you would think. My company for example hires 5 people and fires 7-10 people a week. So a lot of the LTL(Less Than Truckload)companies are being staffed by complete novices.
For those who have never used a forklift. It is notoriously easy to miss the pallet and damage the product. Using one properly is a lot trickier than it looks. Looking at the photo the pallet looks great why? Because the forlift driver clearly didn't have his forks lowered and spaced properly. Mix the difficulty of using a forklift with the influx of new hires with little experience and this is where a lot of the damage is coming from.
Next the shipper. The LTL Freight Industry (Ups, Fed ex, Old Dominion, R+L,etc) has too much freight and not enough companies and drivers to deliver it. New England Motor Freight a big company went bankrupt. When they went under R+L had to pick up the slack. Companies don't care about damage because they don't have time to care. If you reject a delivery it just goes back to the terminal and sits in a corner till someone arranges for it. If a product gets to the terminal and its damaged they still have to deliver it.
How Trailers are Loaded. Most LTL drivers do not load thier trailers the warehouse workers do. There's a way to load trailers and pinball machines need to be placed as close to the front as possible. The closer to the back of the trailer an item is the more likely an item will tip over. Unless instructed Companies will not ratchet strap or place any kind of safeguard meaning that the pallet is the best support its gonna get. If you can ALWAYS ALWAYS ALWAYS buy a bigger pallet.
If anyone has any questions I'll try and answer them
