The 1980s-era
Winchester Burley
bicycle trailer I've been using for a few months finally packed it in today. A steel tube ripped. This steel tube was welded at a right-angle to both tube segments which held the wheel axles. It ripped just below the welded join with the axle tube for the left wheel. It took a good hour for the tube to rip all the way through. As the rip progressed there was less-and-less to hold the left wheel at a right-angle to the road surface; the loaded trailer box was pushing down, and the unbraced axle couldn't maintain a right-angle, and was hinging upwards, driving the top of the wheel towards the side of the trailer box.
