HSE TOWER CRANE SAFETY ALERT 24 JUNE 2010
Manufacturing defect identified in certain tower crane mast spigots
A manufacturing defect has been identified in spigots on K600 and K800 mast sections used in Manitowoc Cranes, Potain MD, MDT and MR Tower Cranes. There have been two known mast section failures from this cause.
Action is needed to identify any other potentially affected mast sections and ensure they are taken out of service immediately then quarantined for further investigation.
See full text of HSE Safety Alert 24 June 2010.
Action required
Stored Mast Sections
Identify and record mast PIN numbers and full spigot numbers (including the letter at the end) for all K600 or K800 series mast sections. Any with spigot numbers in the range specified should be withdrawn from stock immediately and quarantined.
In use Mast Sections
- All erected Potain tower cranes should be scrutinised to identify any mast sections with PIN numbers in the specified range.
- Any erected cranes with the relevant mast sections should be taken out of use immediately and arrangements should be made to: (1) either dismantle the crane sufficiently to view spigot numbers on all relevant mast sections. Record all spigot serial numbers and, where they are in the potentially affected range, take the mast section out of service and quarantine. or (2) weld additional sections in accordance with the specification provided by Manitowoc Cranes. This work will need to be undertaken following a safe system of work and to an assured quality standard. Welds must be inspected and non- destructively tested on completion. Arrangements must be made for documented competent person weekly inspection of the welds and at least monthly non destructive testing for the entire time the crane remains erected. Manitowoc Cranes can advise.
- Whichever option is selected, the work must be managed rigorously to ensure the safety of anyone who might be affected. Safe systems of work, safe access and competence are key elements.
- Please retain mast sections for further possible investigation by HSE. We will not be able to complete investigations if we do not have further supplies of spigots to test.
