2004 KENDON DUAL RAIL TRAILER Structurebody Problems

ON JULY 21, 2017 MY KENDON TRAILER, CARRYING MY TWO SUZUKI DUAL SPORT MOTORCYCLES SNAPPED COMPLETELY APART AFT OF THE COUPLER AND THE SAFETY CABLE ATTACHMENT WHILE TRAVELLING ON THE INTERSTATE. THE TRAILER, WITH MOTORCYCLES LEFT THE ROADWAY AND TUMBLED INTO A ROADSIDE DITCH. THE BOTH MOTORCYCLES WERE TOTALED AND THE TRAILER WAS DAMAGED BEYOND COST EFFECTIVE REPAIR. THE NECK OF THE TRAILER WHERE 3 ROUND STRUCTURAL STEEL TUBES COME TOGETHER, AFT OF THE COUPLER COMPLETELY SEVERED. THERE WERE NO OBVIOUS VISIBLE SIGNS OF A DEFECT PRIOR TO THE ACCIDENT, NOR DID THE TRAILER FEEL WEAK WHEN IT WAS MOVED BY HAND AND PULLED TO THE TOW VEHICLE. THE TUBES BROKE NEAR WHERE THEY WERE WELDED THROUGH A TRIANGULAR COLLAR PIECE THAT THE TUBES PASSED THROUGH. I'VE NOTICED NEWER DESIGNS OF THIS TRAILER DIFFERED STRUCTURALLY IN THIS AREA, LIKELY CORRECTING THIS DANGEROUS FLAW.

TUBE FRAME FAILURE. WELD CONNECTING LOWER TUBE BROKE AWAY FROM TUBE BODY CAUSING ADDITIONAL STRESS TO UPPER TUBES RESULTING IN STRESS CRACKS IN THE SIX O'CLOCK NON VISIBLE AREA. ADDITIONAL USE OF THE TRAILER AT 50% LOAD CAPACITY RESULTED IN FAILURE OF THE REMAINING TUBES WHILE TOWING. CAUSING TRAILER AND MOTORCYCLE TO FLIP AT SPEED , CROSS 2 LANES OF TRAFFIC AND COMING TO REST AGAINST CENTER DIVIDER. RESULTING TO TOTAL LOSS OF TRAILER AND MOTORCYCLE.
