Hagglund BV 206 Aframe tow bar

[rob love]

About 14 years back, when I was still in the military, C battery still was using the BV206 to tow the GIAT. The BQ had ordered an A-frame, and they had been listed in the supply cat as KM-local purchase. In the end the battery sent an existing BV206 a frame downtown to a welding shop. and they made up a pretty good copy. It was expensive as hell mind you. I remember thinking, on seeing it, that we could have shortened an M-series a frame for a fraction of the cost.

Rob,

I am a welder and fabricator by trade and in my sleep I have made this item several times over.

I would however, for the sake of being a purist, like to nail the copy more closely than what I think it should be.

I already know that the attachment coupling has to engage the round horns and clamp to them. I have fairly well thought out that part.

I know that the moment I start to cut steel and weld, an original one will pop up for $25 from 20 kilometres away no doubt.

I will send an email to MILMAC and see what they can scare up for me

Here are some pictures sent to me from a CF member out west of what his unit has, who made them I do not know but they are what is needed to mate correctly to the BV206.

The last picture shows you the "horns" at the front of the vehicle that it couples to.

Thank you to all involved

Instead of trying to visualize a complicated set of angles and clearances, why not weld a few 90-degree tabs onto some telescoping tubes that have offset thru pins? This way if the BV's attachment point works best with the tab face up, or left or right, a telescoping joint in the middle can be swivelled 90-degrees or 180-degrees as required. Put in a cross pin or bolt. Give yourself a ring or whatever the towing vehicle's hitch needs, and proceed with due care. Check the chains every mile or so, and before any exciting parts of the route.

The objective is to put enough hours into the job back at the shop to limp the BV out of harm's way and closer to a better tow rig.

Dear Terry,

Thank you for your comments, however, no.

The photos shows the "proper" towing frame that has been designed tried and tested. That is what we will use.

Our objective is to make and use the proper kit for the job which is proven and safe. There is a lot going on when towing a dead Bv206.

It is a simple fabrication job, I have 3 to make for various owners

So timelines have stretched and it is only now that I am starting to make the component parts.

The lunette pieces are a bought in item at my retail cost of $30 a piece which considering I have made a lunette before, a long complicated pain of a process, I am happy to pay to avoid doing over again. It has a 5 ton capacity.

The C shape ends that engage the horns on the BV have been made over this jig and some heat. They obviously are made long and trimmed. I'm off to a mates shop who has a 3/4" drill and a very substantial drill press later today.

So there is no confusion, the soapstone markings for the holes were done after the bending process.

I will hopefully get two sets and maybe the third fabricated over this long weekend.

Hope it illustrates the method clearly for all to enjoy

Drilled a bunch of 3/4" holes today. Am coming up with a farmer simple securing system for the nut, and obviously will be shortening the bolt.
