In a written statement to ConnectingCranes, Terex's director of product safety Norman Hargreaves played down the significance of the failure. 'It is obviously very important that crane users be informed of any significant product issues,' he said. 'However, there are additional facts of which you should be aware: Terex is aware of only one sheave failure (involving the RT 175 crane owned by the Navy that was discussed in The Crane Corner article). The investigation of Quadrant Engineering Plastic Products, the sheave manufacturer, found there had been severe side loading on the Navy RT175 crane involved in the accident.'
