TWO CLEVER PLANS
I designed a bracket that locks my caravan to my vehicle as soon as I hitch it. It fits right below the top part of the tow bar and I also have a chain that fits over the coupler’s handle. You can also just use the lock and lock it to the coupler so that no one can try to unhitch your caravan. It didn’t cost much because I already had all the materials. This included a small nut and bolt as well as the lock. The two washers and chain were R20 at a hardware store. I cut a section – about a quarter – out of each washer, turned this piece around, and drilled in a small hole. These loose parts I welded back on to the washers but so that the hole faces away from the washer. I put the two washers on top of each other and on the part on the other side of the hole I drilled in a bigger hole through both washers. You can fit a bolt through this as well as one part of the chain. These two washers look like a bracket where the two parts separate so that it fits over a tow bar. The lock fits into the two holes that are now on top of each other as well as the other side of the chain – everything nice and safe. I also made a plan so that it’s easier to extend the corner steadies to the ground. I bought a secondhand 19 mm socket for R10 and welded it onto the top of a 10 mm steel bar. This fits into my cordless drill and the hassle with the handle is in the past.
