INSPECTION CHECKLIST
Use the following checklist to record any damage found
while inspecting lattice sections.
If no damage is found or the damage is within the allowable
criteria, check the box next to the item to indicate that the
section is okay.
If the damage is not within the allowable criteria, indicate so
in the box next to the item — for example: D to indicate
damage. Then make a detailed report of the type and degree
of damage found. Space is provided for drawing sketches or
attaching photographs.
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.
WARNING
If damage found that is not within allowable criteria, do not
operate crane until appropriate lattice section has been
properly repaired or replaced.
Operating crane with damaged lattice sections can result in
structural failure or collapse of attachment.
