    Post Project 2 from Rambozo. Category: Automotive On Road Trailer Jack

    Remembered to download camera at last. So here is the first thing. Put a new jack on an equipment trailer.
    This is what was there with someones idea of a battery box for the old electric brakes. (Has been converted to surge brakes).

    I wanted to try out the TIG setup on the 140ST, but with only 120V it wasn't quite up to the task for the thick stuff.

    Switched to stick and 6011 and it was all good. Just some stitch welds every few inches, to keep the heat out of the jack and make it easier to cut off after it gets destroyed. Actually this will be the second one of these I have used and so far they are holding up much better than anything else has. HF drop leg 3500 lb. model. Not sure it would really lift 3500, at least more than once. But it does ok for this and is much nicer than a top crank.

    A little cold galvanizing primer to hold it until a someday paint job.

    I haven't see that jack there before. Going today, will have to look. I have a trailer now with the electric lift on it, slow, but very nice.

    I think it's on special and with the ubiquitous 20% coupon, out the door was like $25.

    It comes with hardware to make it swivel, but with the drop leg it seems much better to just mount it solid. Around here all the swivels get messed up. Even with the pin on a chain, it disappears, then someone uses a bolt or something and it starts tearing out the hols and leaning on it. before long the whole thing is junk.
    I put one of these on a car hauler the same way, and so far it has help up pretty good.

    All mine are drops as well. But I see them all the time, leaning at an angle, and no worries on it spinning down while going down the road.

    That looks like a nice little trailer. That galvanizing primer will hold up even after the metal underneath it disintegrates. I like the electric lift idea the best, even if it is slow.

    I also like the location where you mounted your jack. If I had done the same thing years ago on my home built trailer, the 12 gauge top wouldn't have flexed and gotten all wavy looking after everything was painted! Minor design flaw of mine....back when I was a minor (and knew it all)! The top crank jack is a hassle too.

    Congratulations on passing inspection, dealing with some of those inspectors can be a real pain!

    Made it two years before it was trashed. Depending on what implement is attached, sometimes the tractor is way up front, and overhanging the tongue. Hate to think what the tongue weight is, but the HF jack finally called it quits. Time to pull out the big guns. A 10,000 pound lift drop leg Bulldog should do the job. I was on the fence about going with the two speed gearbox version, but decided not to. As it was I was blown away by how stout this thing is. I didn't notice that the shipping weight for this jack was almost 200 pounds. I just looked around and everyone gave Bulldog glowing reviews for toughness. Even with the tractor pretty far forward, I can crank it up with my little finger. The drop leg even has a spring return to lift it up. That spring is even quite the beast. I'm sure it would break or remove a finger left in the wrong place.
