Remove and Inspect the Boom
Extend/Retract Cables
Genie specifications require that this procedure be
performed after 12 years.
Manufacturers specifications require that this
procedure be performed by personnel that are
competent in cable / wire rope inspection.
Note: If the cables pass inspection and are not
replaced, the cables must be removed and
inspected every 3 years until all boom cables
have been replaced.
Note: Additional or more frequent
inspections may be required due to the
following:
•
exposed to hostile or corrosive
environmental conditions.
•
boom is overloaded
•
sustains a shock load
•
electrical arcing
•
unused for extended periods
The boom extend and retract cables are
responsible for the extension and retraction of the
boom tubes. Inspection and replacement of the
boom extend and retract cables, when required, is
essential to good machine performance and safe
machine operation. The boom extend and retract
functions should operate smoothly and be free of
hesitation, jerking and unusual noise.
