Laugh for you this morning? First reading this I thought you were referring to members of the broken cross on trailers---- Then I thought no that can't be right he has to be talking about the symbol on trailers. (the upside down cross or better known as the peace sign)
Then I had a couple sips of my coffee and read the entire post and decided I should have started with the coffee rather than the computer!
This may be way off base, but is it possible the damage came from above? Have you checked the floor of you trailers near the damaged cross members?
How about sloppy hook/unhook: not being aligned with the trailer; tugging without raising the landing gear; etc. Lateral stress will do the landing gear and cross-members no good.

I have been in trucking for over 35 years and have never seen so many trailers with broken cross-members as I have in the last few months. Does anyone have any idea what would cause this damage to numerous trailers? none of the drivers have had any blow outs on their tractor tandems that would create flying rubber to wipe out the cross-members. Spotting unit has a very short frame ... could no reach the 4th cross-member to damage it. No damage to fifthwheels or rails to reflect possible interaction with the cross-members. Looking into possible damage done while dropped at other locations. Any ideas?????
Tandems:
Tandem Axles
A set of axles spaced close together, legally defined as more than 40 and less than 96 inches apart by the USDOT. Drivers tend to refer to the tandem axles on their trailer as just "tandems". You might hear a driver say, "I'm 400 pounds overweight on my tandems", referring to his trailer tandems, not his tractor tandems. Tractor tandems are generally just referred to as "drives" which is short for "drive axles".
