5 wheel boggie

  1. Have had a couple of machineing jobs this week so only got back on the welder this afternoon, i have 2 of these to send to colchester there towing dollys so tractors can pull artic lorry trailers.

    Went to the scrap yard and amputated the donor parts, cut the rear off an old 40ft trailer, turntable plate came off a volvo, brake cylinders will be sent and overhauled, and hydralic brake valves also added so we have a duel brake system. once the dolly is built it will go to the shot blasters then paint shop.

    First job is to shape out the drawbar with the plasma, 8" UC is used on a 3/4 wall, I take no chances with the strength you could have 20 ton being hauled at 50Kph.

    The hook end is heated and clouted to give it a nice strong V.

    The hook is shaped into the UC so i can weld it on all sides.

    3 passes should do it, cross plates are next in line, but i am haveing the weekend off :) for a change so will post some more pics up next week.

    Have you finished this one yet? I'm so used to seeing trailers the farmer has made from old artics that I didn't realise the hitches could be welded on neatly (or that you could even get purpose made hitches to weld on).

    On our farm most of the towing hoops are gas cut from 1/2 inch plate, and arc welded on to some crazy construction. It's interesting how many different ways they can fail, and how they get repaired over time.

    Good to see a well thought out job too.
     
  3. Thanks malcolm, got stuck doing those skids i posted up for that combine, I fitted them up today so i hope to be on it tommorow although a local fitter is bringing a couple of ally jobs over at some point, ahh need two of me really at the mo, The rings are about £20 and come with a prep and weld plan. Iv seen some terable cut and shut jobs on these and some by so called pro welders, I would never wish to be in the position were a fault has occured through my error so i like the boot and braces method, post up some more pics as i go though its booked at the paint shop next wednesday:o so it will be sooner than latter......
