snapper Posted March 18, 2015 Share Posted March 18, 2015 Well its different from the usual trucker mistake threads we usually have here. A trailer carrying a steam train has collapsed in Coldharbour, Wareham. It is thought it will be moved overnight. https://twitter.com/BBCDorset/status/578265168934760448/photo/1 Quote Link to comment Share on other sites More sharing options...
Broithe Posted March 18, 2015 Share Posted March 18, 2015 I was an early adopter of CDs in the mid-1980s, and people often came to my house for a demo, before committing themselves to a purchase. One of my demonstration CDs was a very good steam train sounds one. During one demonstration, the 'target' got up to stand in the centre of the room, for the best effect. A low-loader, similar to that above, complete with steam engine, sailed slowly down the street, exactly in time to the sound-track. Poor chap thought he was hallucinating.

DiveController Posted March 20, 2015 Share Posted March 20, 2015 So, a lesson in axle-loading to be learned here? Quote Link to comment Share on other sites More sharing options...
Noel Posted March 20, 2015 Share Posted March 20, 2015 So, a lesson in axle-loading to be learned here? Looks more of a problem with the trailer beam loads rather than the axle loads. Metal fatigue or insufficient strength, or something else? Quote Link to comment Share on other sites More sharing options...
Mike 84C Posted March 20, 2015 Share Posted March 20, 2015 Its a very clean straight break, I wonder if the trailer has been streched at some point in its life and that has created a stress area. Be interesting to see if it is in both chassis rails. Quote Link to comment Share on other sites More sharing options...
Broithe Posted March 20, 2015 Share Posted March 20, 2015 There is what could be a weld fillet in the top, immediately above the break in the bottom. I wonder if there has been an extension welded in at some point, and the tensile part has failed, propagating to the weld up the back of the web with the shackle through it? Looking through the gaps in the wheels, it does appear that both sides have failed in similar ways. Quote Link to comment Share on other sites More sharing options...
