Genie specifications require that this procedure be
performed annually.
Manufacturers specifications require that this
procedure be performed by personnel that are
competent in cable / wire rope and sheave
inspection.
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/retract cables and sheaves are
responsible for the extension and retraction of the
number 3 boom tube on the S-100, S-105, SX-
105XC and S-100HD and the number 2 and
3 boom tubes on the S-120, S-125, S-120HD and
SX-125XC. Inspecting for foreign objects, damage
and/or improper adjustment of the boom
extend/retract cables on a regular basis 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.

stowed position.
