ok moore i know? the company that i worked for at the time didnt have a clue about safety inspection stuff and wouldnt spend money on it.
i brought the truck home and new i was putting 9000 lbs on a 10,000 lb rated trailer and whoever they had hook the trailer to the truck for me didnt check anything so good to go right? NO? went off down the road and felt the trailer float going over a railroad track it stayed with me surprisingly.
got pulled over and the bolts were tight probably because i had just used it the day before the problem was they had put a 2-5/8" tongue on a 2" ball.
my load was the next morning so when i got home of course i switched to the correct ball and welded the plate solid and the ball.
they only used that truck for heavy haul.
after i was done there were only two trailers they could hook to it.
next morning i put a 7900 lb chiller in the bed of the truck and a 9000lb chiller on the trailer and drove it where it needed to be with no care in the world because i knew everything was welded solid.
yes if you are relying on bolts please check them every now and then.
alot of variables in this.
your bumper is welded solid?
my frame extensions and bumper were by collins but the bumper was bolted on for easy replacement i assume?
my bus before me had a hitch welded solid and the PO didnt like it so he cut it off.
kind of helped kind of didnt. he claimed bad welds but i only saw what was left i say they used the wrong welding machine. decent looking welds but not enough penetration.
my factory bus chassis extension was welded from the factory but i drilled and bolted a new hitch on cut the bumper for the square neck receiver some 3/8" plate to make spacers to clear the body to chassis mounts a couple of clevises that match double the trailer weight loaded and done?
oh wait a 7 pin wiring harness to handle an electric brake axle trailer.
now to work on building a double axle electric brake car trailer.
starting to look at NEXTRAIL aluminum stuff.
it is going behind a shorty with hydroboost.
i think the braking system combined between the two is key regardless of load.
regardless of tongue weight the vehicle has to stop what is hooked to it behind it or whatever interpret what you want.
when i have a crane on a job sight its not what i think it can do and through all the paper work and govt crane inspection during setup approved if things go south it is the operators problem not the contractor or the govt.
the crane operator/company said it will do and put equipment there to do it.
it failed? the crane operator/company is responsible.
if you lose a trailer from a customized bumper your at fault
