On certain digger derricks, the pole guide plate may not have been welded properly. As a result, the weld could crack, and the retaining pin could separate. If this happens, the pole guide arm could fall.
Safety Risk
A pole guide arm that falls could create a risk of injury to people nearby.
Corrective Actions
Terex will notify owners by mail and provide you with instructions for how to inspect and replace the pole guide plate, as necessary. Terex advises you to perform a daily inspection of the pole guide plate welds, and not to use the digger derrick if a weld is cracked.
