Re: "Safety" cables - replace them with chains!

Post by c130king »

Mine came from the PO. No idea where he got them. But they seem pretty darn strong...galvenized steel I think...not aluminum.

Please don't post any horror stories of carabiners failing...I don't think I can take any more... :o :?

Here is a pic of my chain set-up. I have never crossed my chains before...nobody ever recommended that before...but I will start now. I am getting ready for my 450 mile trip in a month so I am reading many threads on trailering. Are these chains too slack? Should I make them tighter? Unfortunately the pic isn't good enough to see the carabiners.

Thanks,

Too slack...you should maybe have an inch of droop under the tongue max...another way to get it right is to take them off, and the turn the tow vehicle into a tight turn to the right, and now clip the LEFT chain on so that it has minimal slack..now turn the trailer left, and set the RIGHT chain. Mark them with sharpies or a peice of red pre-flight check tape ( :wink: ) and you are all set.

I have to confess its amusing to see a C130 pilot post he is concerned about trailering.... :D :D - all comes down to the comfort of the familiar I guess!!

If you have greased your bearings in September, the 'boat sitting' wont be relevant - the wheels will be fine. Check those tire pressures right before you leave of course and bring your own compressor and gauge. Pay up your 10 USD and join Trailer Boat US too!!

On carabiners - disclaimer, I am not an Mech Eng, so you should confirm the below before risking life and limb.

A 2 inch SS carabiner from We$t Marine list a Max Working load of only 66 pounds, which probably means a failure load of something like 600 pounds. My uneducated guess is the shock load of a trailer chain from a disconnected trailer will exceed this, especially if the hitch hits the ground and digs in at all.

A 1/4 inch shackle from WM is 4 USD and has a safe working load of 1000# which means a failure load of 6000# - thats more like it.

I think that is a strong case for not using carabiners on tow vehicles chains....you might be equivalently attaching your chains with string.

In an old age moment, I have a feeling I went through this discussion with myself some years ago.

Stephen,

Thanks for the feedback. I will tighten up the chains...and cross them. Was always afraid I would have issues turning if I tightened them too much.

Checking air pressure is on my pre-flight check list. I have been a member of BoatUS Trailering since before I brought the boat home for the first time...I believe in insurance. And based on your and several others recommendation I stop about every 60-90 minutes and check everything.

As to the carabiner...it looks very similar to the closed connector ring shown earlier in this post. It looks/seems very thick, strong and heavy duty to me. But I will look for two of those closed connector rings for the trip back to Jacksonville.

Never afraid to fly a C-130 with any load...I always knew I had a professional team of Loadmasters ensuring everything was secured properly. Don't have that luxury with my trailer...I am far from an expert in that field...I depend on all my friends from this website for advice & guidance...and I have a history of a few trailer snafus that my wife refuses to let die... :?

Cheers,
Jim

I think that we are having a terminology disconnect here. I think that what Jim is referring to is a quick link like this and not a carabiner.

Rich,

I have a carabiner. It is this shape:

Image

But it is heavy duty galvanized steel. The spring loaded arm is very strong/stiff. I can't find one online just now...I will keep looking.

I defintely think it is much stronger than the 66 lbs that Stephen mentioned. But probably not as strong as the one you pictured.

Cheers,
Jim

My mechanic told me these were legal for use on towing chains in Canada .

I have surge brakes that won't work unless the toung is in the ball. That being said if the toung isn't in the ball you should have a pin that you put thru so you know it is locked in. That Pin won't go in if you are not locked in.
I have a tandem aluminum trailer and with a large length bar to hitch, if that happened to me, the toung would have gone under truck and the front trailer lift would have hit my Bumper (my lift doesn't fold) and prevented the winch leg from hitting the body of the truck.
Sorry about your mishap and we all make mistakes. Like SH...t Happens
We all learn from these experances and opens the mind a little more that this can happen.
Thanks for the info.

My new trailer came with safety cables instead of chains. These are coiled, plastic-covered steel cables that are several feet long.

I brought Bossa Nova back from my marina to a storage-yard close to home last night. By the time I was ready to go, it was dark. I didn't connect-up the hitch properly, but I did secure the safety cables and the breakaway brake cable. Two hundred yards out of the marina gate, the boat fell off the hitch. I braked to a stop - and - CRUNCH!

Image
The cables, as you can see, were long enough to let the winch-post smash into the back hatch of my tow-beast. The breakaway brake cable was the same length, so it didn't activate the trailer's brakes. Now the hatch is jammed shut. The tongue may have done more damage underneath; my speedometer doesn't work, several warning lights stay on, and it takes a lot of force to shift the transmission out of "park".

A good samaritan who lives down the road from the marina brought a floor jack to the crash scene, and he jacked up the trailer high enough to fold down the dolly-wheel. I was able to hitch it up, and we each of us checked it carefully to make sure it was on properly this time. The car was still drivable, and I got the boat to its new home (and then got myself home) without further incident.

Safety chains of the proper length would not have enough "slack" to cause this damage. I'm sure the winch-post would have been snubbed short of the hatch. The hitch would have had nothing to hit but the spare tire, which is mounted just forward of the hitch-receiver.

Please learn from my sad experience!

What KHE said!

I had my slack about 1/2 of yours (and crossed, of course)

Rick :( :macm: Less

For C130king...A nice setup, and I am now very jealous, but those chains are just too slack. Only my 2 cents worth, but cross and shorten them so there is just enough slack to turn corners...and even if they are TOO short, it will only skid the trailer a bit and will prevent a slow motion jackknife on a tight corner...Also its a good idea to remove the jockey wheel from the bottom of the wind down tube...just in case to go over a higher than usual kerb...
In the good old days when i had SEAHORSE, SOB, SOB, I added a second jockey wheel to overcome the problem of when the front of the trailer was too close to the ground to remove the supplied one...

All,

Thanks for the feedback. I will be doing the cross and tightening up the chains...just needed someone to show/tell me that is what is necessary...I didn't really know.

And I always remove the jockey wheel...it was just still in place in that particular pic...and that particular pic was my very first time pulling the boat out of the water.

But I will still be nervous during my trip to Mississippi in 15 days. Did a slightly longer trip back in 2007 but I hadn't read all the horror stories back then...ignorance really can be bliss.

Can't wait to get back.

Cheers,
Jim

Hey Puggsy,
Unrelated, but, I really like your float-doodle guide system on your trailer. Inspired to make the same mod on my trailer, as I recall my first trailer-docking experience in a stiff beam wind blew "Nameless" off the trailer at the bow.

Thanks for the pic.

Heh, heh...Yeah, good times! I once utilized a "helper" who managed to allow the bow to wander away from the winch tower and turn my Mac perpendicular to the trailer between the winch & wheels! Good times indeed! :|
