    Default Simple Tipping Trailer Conversion

    I've had the idea of making a tipping trailer for a long time, although it was always based on a hydraulic lift, the expense of which was hard to justify. More recently, I saw it could be done with a simple mast and winch setup, which is a much cheaper proposition.

    So I just got me this 6x4 off Gumtree

    And I think the conversion should be pretty simple - I cut off the drawbar and springs, build a simple sub-frame comprising 2 rails, 2 or 3 crossmembers and the previously-cut springs and drawbar.

    The rear of the sub-frame will stop about 300mm short of the end of the trailer, which will be the pivot point. Then I add a mast and winch on the drawbar to lift the front of the tub and I'm done

    Existing chassis is all 40x40, so I'll use the same for the sub-frame.

    Only thing I haven't worked out yet is the hinge arrangement.

    I've been going down the same track with my currently tilting trailer. A hydraulic lift would be ideal, but like you, I can't really justify the cost for the occasional load of mulch or concreting gravel. My trailer hinged on the axle and the tail hits the ground long before anything much will slide out (I hate shovelling stuff out of trailers as much as I hate shovelling the stuff in). The axle mounted hinge also means that the trailer hangs down at the back when loaded, so could do with a bit of conversion like yours. I have been saving pictures of all sorts of tipping trailers in the hope of getting some good ideas. The mast setup comes up quite a bit and seems to work well. Certainly a much cheaper option for occasional use and I am giving it serious consideration for my trailer. I have also considered a "scissor" style lifting mechanism under the tray and the hand winch mounted horizontally to pull the tipping mechanism to ovoid any obstructions that a mast might give. I have no idea whether there is any mechanical advantage to either tipping method.

    I have a ute crane stored in the shed and maybe that could be mounted at the front of the trailer and serve double duty for the tipping the trailer and lifting heavy stuff into the trailer. There was a tipping trailer advertised on Gumtree I saw the other day that used an exhaust jack to tip the trailer, so that could be an alternative too.

    I look forward to following your conversion. It will be interesting to see how well your mast and winch tipping setup performs and how much winching/winding force is required to empty a trailer load. Keep the pictures coming.

    For the hinging, use a couple of 10 mm plates either side of the subframe, use a piece of hollow bar welded in a notch cut into the centre of the RHS. Instead of the 40 X 40, I'd use something like 75 X 50 for the main frame, the reason being that the 40 won't bend is because it has the sides of the trailer to support it, whereas the 40 on its own will bend because the weight will be on both ends of the frame with the main load supported/pivoting on the axle.
    Using the 75 X 50 will allow you to have the drawbar and chassis in one, have the coupling bolted to a plate under the drawbar, with a gap of 100 mm, with a 45 degree slope from the top to the bottom, just looks neater.

    XJ90X, Your idea will work, you'd need to make the scissor lift approx 200 mm wide, using probably 25 X 50 X 2 RHS, to make it stable. Framing will need to be 50 X 50 X 2 underneath on the scissor section, otherwise it'll bend.
    To make less effort winching, mount a pulley onto the point of < and run the cable back to a point in front of the winching point, it'll halve the effort required to lift the load. If you think that there'll be a few loads of heavy stuff to tip out gravel, loam etc. design the system to accept an extra pulley on top and one below. Similar to Grandads rope pulley block. It'll take longer to unload but, the grand kids will be able to unload the trailer.
    Use a winch that has a brake built into it, NOT the ratchet type boat trailer winch. They are unreliable on the downward movement!!!
    Hope this helps,

    If you are interested in alternatives
    This is my slightly different version of a tipping trailer. The pivot point is close to the point of balance so not too much effort is required to tilt it. It has the added benefit of being able to remove the drawbar for storage. I actually store this trailer vertically behind my gate, using a block and tackle to hoist it up.58E9232D-5EAC-4743-AF9A-5809DC47C8D6.jpg
    Due to the drawbar being removable, l made it longer than l normally would have, which makes it easier to reverse.

    Thanks for the responses. I'm after a 45 degree or steeper dump angle to ensure material dumps completely. I've found another commercial example to work off:

    Premium Off Road Winch Tipper Single Axle Trailers - Caravans & Trailers - Dubbo
    1770-img_4764.jpg
    Which looks even simpler than others I've seen. They give specs too, including 50x50x2.5 SHS for the frame, which I find interesting in light of Kryn's comment about load. They use a telescoping mast, which I might copy, an Ark brand 1150kg boat winch with 3 gear positions and a "launch control brake system", which I've gone and ordered, and I've ordered 4.5" keel roller to go atop the mast for the 65mm winch webbing to run over.

    I thought I had a heap of 40x40 SHS lying around, and, again in light of Kryn's comment, was considering laminating two pieces to make 80x40 side rails, but it turns out I've got a lot less than I thought, but enough for cross-rails and the mast. I did, however, discover some 65x35 RHS, so I think I'll use that for the sub-frame side rails and see how it goes. I'm keen to try and do all this using stuff out of the steel rack, although I think I'm going to have to replace the trailer floor due to rust, and I'll probably buy some 2mm galvanised sheet.

    For hinging, I don't quite get Kryn's suggestion above, but I've ordered some spring hangars that might do the job.

    I converted my standard 6x4 into a tipper, simply by hinging the draw bar about one third of the length from the front. Then welded two pieces of 50mm x 4mm flat sticking out the underside of the trailer by about 50mm. Pointed down at a slight angle.
    To empty, just remove the tail gate, make sure the trailer is weighted slightly to the rear and undo the latch at the front so that the rear tips down to the ground.
    Hop in the car and reverse. Trailer goes upright and load is dumped.

    I don't have the trailer here at the moment, otherwise I would attach photographs.

    Hooroo.
