BOOM, JIB, TOWER, AND MAST
INSPECTION CHECKLIST
TABLE OF CONTENTS
GENERAL
Boom, jib, tower and mast sections (butt, top, inserts) must
be inspected by a
qualified person
for the types of damage
indicated in this check list.
Refer to Folio 1316, Boom, Jib, Tower, and Mast Inspection/
Repair, for inspection guidelines, intervals, and replacement
specifications.
USING CHECKLIST
It is recommended that damaged areas be marked for quick
identification by repair personnel. Brightly colored tape
works well for this purpose. As a reminder, the type of defect
can be noted on the tape.
RECORD KEEPING
A separate copy of this checklist must be filled out for the
boom, jib, tower, and mast on each crane you own.
Signed and dated copies of completed checklists must be
kept on file at all times, as they may be required to verify
warranty or product liability claims.
