Spider lift manufacturer CMC has issued a ‘Non-Mandatory update’ service bulletin for its 83HD+ sold in North America. This safety notice comes after an accident where a boom failed in Wisconsin only a few weeks ago.
The bulletin calls for owners to inspect the boom for damage in the areas shown in the picture below, and if so take the boom out of service and carry out a repair. CMC states that “In case the boom has no evident damage on the bottom part, the boom can be considered safe and can be used according with technical requirements and regulations.”
