Worker Struck By Pile Pipe
Two workers were operating a pile driving unit with a 45 tonne mobile crane. When the operator lifted the hammer, the edge of the pile cap caught the collar of the pile pipe which lifted the pipe slightly. When the operator saw the collar pick up, he immediately stopped lifting the hammer causing it to bounce. The collar released from the side of the hammer allowing it to drop slightly, causing it to kick out at the bottom, striking the rigger.
