I cross my chains when i pull any trailer, will it keep the trailer off the ground if it comes unhooked ?, maybe..maybe not ?, from what i personally have noticed is no..it will not keep it off the ground if chains are crossed..or straight. unless the chains are so short, that would stop the front of trailer from hitting the pavement ?, then no..it will not stop it. same goes for the safety chains being too short, if this is the case, you will not be able to make sharp turns without bending tailer tounge or breaking the safety chains. i do know for a 100% fact, safety chains either crossed or straight ?, WILL NOT KEEP THE TOUNGE FROM DROPPING ALL THE WAY DOWN ONCE THE TRAILER TOUNGE CATCHES TOW TRUCK HITCH SLACK !. now..if you are pulling forward down a road, load weight on trailer tounge ?, then yes..it will craddle it, BUT !!!, once the trailer's tounge catches up to the towing truck ?, then yes...the safety chains WILL NOT craddle the trailer tounge, and stop it from dropping all the way to the pavement. safety chains are not a solve all, keep everyone safe..THEY ARE A BACK UP SAFETY FEATURE..THIS..AND THIS ONLY. If you hook the trailer up correctly ?, then this means the less you need to worry about
Last summer i had my sister pull my jet ski, while i pulled my small camper, before we left the camp ground, i hooked up my jet ski to her truck, checked all latches, safety chains, everything, we got back to my house, and she told me when i was getting out of my truck..she heard noises while we were on the freeway home coming from the back of her truck ?, hmm..i walked around to the back of her truck to unhook my jet ski, sure as shit..the coupler was sitting on top of the hitch ball..but not latched down on it ?..how the heck that happened i have no idea ??..i always lift up on trailer tounge or use the jack to lift tounge up to make sure its attached solid on ball !!, somehow in this case, the latch got loose, and road the whole 1 1/2 hrs just sitting on the hitch ball ??..I HAVE NO IDEA HOW THIS TOOK PLACE ??!..BUT THANK THE LORD IT NEVER FELL OFF THE BALL ?!..THIS JET SKI IS LIKE BRAND NEW, 20 HRS ON IT ( 2015 YAMAHA WAVERUNNER ), not a scratch on it ( at that time ). soo..all you folks that feel the need to cross..or not cross your safety chains ?..IT DOES NOT MATTER...IF YOU DO NOT MAKE SURE THE LATCH TO THE BALL IS CONNECTED CORRECTLY !..please...PLEASE..CHECK..DOUBLE CHECK...TRIPPLE CHECK..MAKE SURE YOUR LATCHES ARE SUCCURED TO THE BALL !.
