LD – Guidance Notes on Inspection, Thorough Examination

and Testing of Lifting Appliances and Lifting Gear

7.2.3 After the thorough examination or the ETE, the

competent examiner should determine the appropriate

SWLs for operating the lifting appliance or lifting gear. It

is important that the numbers of SWLs so listed in the

certificate for the lifting appliance should be equal to the

numbers of readings as shown in the load chart of the

manufacturer's operations and maintenance manual.

Take a mobile crane for example, if the load chart

supplied by the manufacturer contains thirty load

ratings for various jib lengths and working radii,

there should also be thirty SWLs listed in the

certificate issued by the competent examiner. A test

certificate issued by a competent examiner is illustrated

at Appendix III. The item 6 of the certificate is extracted

to form an attached chart of the certificate that shows all

SWLs.

7.3 Scale Down of Load Ratings

7.3.2 The scale down of the original load ratings of a lifting appliance should

be allowed on exceptional basis and provided that the following conditions are

satisfied:

• the lifting appliance has been tested and thorough examined to ensure that

all components are made of strong and sound material and free from

patent defect. The test and thorough examination should accompany with

a nondestructive test to confirm the structural integrity of load bearing

components, joints and welds;

• approval has been obtained from the manufacturer to determine the

amounts of scale down, especially for those lifting appliances the load

ratings of which drop in non-linear scale;

• specified conditions should be imposed in the certificate to ensure the safe

condition of the lifting appliance before the next test and thorough

examination; and

• all load ratings contained in the load chart are proportionally scaled down.

The scaled SWLs should be fully tabulated in the certificate.
