Scary, life threatening, mistake

[MossRoad]

I've used several different trailers over 40 years of driving and never had a similar incident, so yeah, they are over rated, you just need to consider the physics of what's going on. Trailer parking brakes would be more parts to fail or maintain plus would add to trailer cost.

Truck and trailer should have been on level ground, Truck could have been put in 4WD if it had it, Trailer tires could have been chocked, trailer could have had rear jackstands. Several ways to have prevented what happened.

Even if the trailer could have had parking brakes, the operator could just as easily have failed to engage it. It just comes down to situational awareness.

All you'd have to do is pull the breakaway cable and if the trailer battery is charged (like it should be) your trailer brakes should lock.

While it's not a good substitute for an actual mechanical parking brake, it works in a pinch.

Of course everybody has the breakaway setup right? I added it to my trailer several years ago.

 

[Fixastuff]

If it happens keep backing the machine off, don't stop or pull forward.

my old flatbed trailer had 2 rear jacks i added to prevent this from happening.

my current trailer is a tilt bed so i dont have to worry any more.

I would hope so

49 CFR § 393.43​

If trailer has breaks it is required to have breakaway system.

Not me this time.

Drove about an hour from home with son-in-law to pick up a tiller and box blade he had purchased. Just like his tractor he bought them sight unseen over the Internet from a dealer in Tennessee. While he was inside settling the bill I helped the guy loading the equipment and strapped things down. Guy loading said he had a Ford F150 like mine. A few weeks before he had delivered a large tractor when the incident happened.

So he parked on a noticeable incline with the truck pointed uphill. Unchained the tractor and started backing off the trailer. He never said what size, type tractor it was, just that it was large and heavy and didn't have a cab. Just as the back tires were about to go on the ramp, right at the end of the trailer, the the weight difference was enough that the front of the trailer lifted up and the truck's rear tires came off the ground. I had never thought of this happening and apparently this guy hadn't either. Said he had been delivering equipment for many years. Luckily the front wheels were straight and the truck, trailer, tractor, and scared motionless man rolled straight down the hill and into a ditch at the turnoff from the busy main road. According to the man the whole rig rolled about fifty yards scraping gravel with the back of the trailer. A few yards to either side and it would have either gone into a deep gully or out the driveway into a busy road. Don't know how he finally got it off the trailer, Don't know why it didn't happen when loading the tractor. But the guy's voice quivered when he told the story.

Just something to think about.

Jackstands on back of trailer, put truck in 4wd so front axle is in park also. Learned that lesson the hard way when I had a car hauler with ramps.

3 ton jackstands at rear edge of trailer. use them everytime when loading and unloading

The two trailer loading fails I was looking for in one video!

 

[MossRoad]

YIKES!

I've seen them before, but not in one clip! Thanks.

Ouch! I am glad I have a tilt deck. I added hydraulic lift to it so I can actually push down on the back of the tow rig. Although the Reason I added the hydraulic setup is I can drive pallets up on the deck one at a time with my tractor without the front dropping.

Not all electric trailer brakes work well in reverse. Most are designed for forward stopping. I was thinking some of the Dexter axles had a better design.
This could be a false sense of security and get someone hurt.
Back up your trailer and slide the controller to full brake and see if the trailer wheels lock before trusting this method.
