Summary
An investigation examines two hydraulic boom cylinder failures on a crane at Vermilion 252-A. Inferior refurbished welds and mismatched working strokes were identified as causes. Dye penetrant testing had not detected the weld defects. Operators should consider paired replacement when one cylinder needs repair, or verify matching cylinder dimensions.
