Normally the 5 YEARLY thorough examination will be carried out at the drydocking immediately prior to the expiry date of the CERT.
The following is a guide to what will be involved:
A visual examination of the crane cargo gear and its associated structure, wires etc, for signs of fracture, wear, etc.
A load test of the gear, usually using static weights. The test weight will be S.W.L. plus 25% for cranes less than 20 metric tonnes S.W.L. For cranes with S.W.L. between 20 and 50 metric tonnes the test weight shall be the S.W.L. plus 5 metric tonnes. Cranes with S.W.L. greater than 50 metric tonnes will be subject to weight test of S.W.L. plus 10%.
In some cases the yard will insist on drawing the shafts and examining 25% of the working sheaves.
On completion of the examination, the Cargo Gear Register will be endorsed and entry stamped. This will always be countersigned and stamped by the appropriate class surveyor who attended the examination/test.
Where hooks, swivels, chains etc have been re-stamped, it must be ensured that:
Where a new test number is used, a new certificate bearing the new number is issued.
Where the existing marks are used, they must be re-stamped and the numbers verified. On completion of the survey, the Cargo Gear Register must be properly endorsed on the page reserved for quadrennial surveys, and the marks on the relative crane cargo gear matches the certificates. To this end, it is the responsibility of the Chief Officer to ensure that these requirements are met.
