On certain digger derricks and aerial devices, a weld in the boom structure could crack. If this happens, the boom could fail.
Safety Risk
A boom that fails could create a risk of injury for the operator and people nearby.
Corrective Actions
Terex will notify owners by mail and provide you with instructions for inspecting the boom structure. Terex advises you to perform a daily crack inspection of the boom structure welds, and not to use the digger derrick or aerial device if a weld is cracked. The company will repair or replace the boom, as necessary.
