Chaining axle to frame?

Op here...

Think I found the post relating to chains.

Batman99 if your watching. How did this idea work out over time?

This appears to be a single axle trailer maybe not a camping trailer by the looks of the frame. Some box and or utility type trailers are hauled empty at times and this arrangement will take the bounce out of the unit when towing empty.

Not a good idea IMO.

Better to just jack the trailer by the frame to determine the max travel and provide wire slack accordingly.

Could possibly be a form of sway control to keep the unit from tipping from side to side.

My guess would be it has nothing to do with the brake wire, but rather to help in tire changing. The chain would prevent the wheel from dropping down when jacking up the frame. The tying of the wires to the chain might just be to keep them from being pinched between the axle and rubber bumper stop.

Properly routes wires do not need anything more than enough slack to move up and down. Mine have been out in he open for near 20k miles with no issues.

No need to over complicate things.

After reading your link... it appears to be someones's idea of how to control/protect the wires going to the brakes.
I have chains that I attach to my rear axle when I pick up the back of my toad so the axle/tires do not drop down. Click on "How I tow" below.

:h What was he thinking? It would limit spring travel and lead to early brake failure when the wires get torn off.

Looks like chain is to limit downward movement (unloaded) to prevent brake wires from being pulled/broken
