maximum safe working load permitted for
the size wire rope being used. This test
should be performed in all working motions
except travel. Buckets, magnets, and so
forth, may be removed for testing wire rope.
No test is required after reassembly.
Retesting is not required when the end
attachment is changed from the original
connection (that is, changed from clamshell
use to dragline, and so on) during the
certification period.
Load Test Certification
After the test, the crane test mechanic and
the crane test director will jointly perform an after
inspection of the crane. This inspection is
documented on the Crane Condition Inspection
Record.
Upon successful completion of the inspection
and load test, the certification of the load test and
condition inspection (fig. 3-19) must be prepared in
triplicate. The following items are documented on this
form:
1. USN number of the crane
2. Type of crane
3. Rated capacity of the crane
4. Boom length of the crane
5. Location
6. Test date
7. Reason for test
