I've had many dock workers tell me that I didn't need to secure the freight with load bars and/or straps... but I did it anyways. Whenever I was asked why I was using more than one load bar and/or strap - I told them I was looking out for my family and their family.
I don't know who's behind me, I don't know how close they're gonna get to my tail.
I'd rather have a strap or bar get damaged than hurt somebody.
Besides... it's all tied into one word - SAFETY.
When I've been asked why I want to see a load... as a driver?
I've been told many times that I don't need to see it. Maybe they're correct in that I don't NEED TO SEE the load... but the load really is not what I'm very concerned with - it's the securement of a load that I'm VERY Concerned with.
I simply tell them (whoever it may be) that I have a right, as a CDL driver, to see how equipment that I'm responsible for operating, is being used and how it's loads are secured. Any company safety officer and any DOT officer and/or law enforcement officer will back a driver up on load securement issues.
I had a pallet collapse with a heavy equipment bearing on it... the dock workers were telling me they were going to file a freight claim... Well, upon opening the doors I quickly went back to the cab and grabbed my camera before I hit the dock. When they mentioned freight claim, I said as I pulled my camera out of my pocket "well, let me just take a few photo's with my company camera while you go get the paperwork ready".
There were 6 straps on this load, none were loose.
Needless to say, a freight claim was never put in...
because the pallet broke under the weight of the load.
I'd rather have a load secured too much, than not enough.
As far as drop and hooks, I've done plenty of them with 53 foot trailers. Why? Most of the time they're full loads with very little room for movement. Or, they're large piece loads, like rolls of paper - that won't go anywhere without alot of help.
Flatbedders secure loads tightly due to wind and weather elements.
Dry Vans don't have that element to contend with.
Flatbedders need to secure tightly because wind will shift a load, so will water and ice. Flatbeds have nothing to protect the loads except the straps or chains on the load.
Often times flatbeds go offroad (like gravel/dirt roads) too, where loads can wiggle more. DryVans don't do that nearly as much. Sometimes flatbeds have to drive into a field where there is no road. Dry Vans don't do that nearly as much.
Secure your loads, no matter what you drive. Take precautions to check tire pressures. Check doors, and decks, and load bar/strap tracks as well to keep track of problem areas.
Strap tightly, I use straps on both sides of a load if possible.
I also find it's helpful to use straps in conjuction with load bars.
First I put a load bar at the floor to secure the pallet.
Then I use a bar across the middle of the load - or "about" waist to chest heigh.
I then use an X pattern with straps, along with strapping horizontally as well.
Ultimately, I like straps better, simply because they're more reliable in my opinion.
Load bars can pop loose. Some Load bars push walls out, some just latch into a track. Straps always pull the sides of the truck in towards the load.
But, that's just me.
