What Is Insulated And What Is Not Insulated - Versalift VO-452-MHI Operator's Manual

Area 1, Boom Tip Area – The boom tip area does
not provide insulation. This area includes everything
past the insulated section decal* on the upper boom.
This includes the upper end of the boom, platform
support, platform(s), controls, and the jib/winch/rope
(when so equipped).
All components at the boom tip area must be
considered to be conductive and electrically
connected, even with an insulated liner in place. Any
contact with a ground and a phase or between two
phase conductors will create a hazard of serious
personal injury or death. Contact between an
energized conductor and any part of the boom tip
will energize the entire boom tip.
When working near an energized conductor, ground
conductor, or other grounded objects, the operator
must use the proper safety equipment (such as
rubber gloves, covers, hot sticks, etc.), maintain safe
approach distances, and follow company work
practices.
Area 2, Upper Boom Insulation Section – This
section provides insulation** between the boom tip
area and earth ground when clean and properly
maintained. On some configurations, it is necessary
to extend the boom until the insulated section decal
is visible.
Area 3, Intermediate Structure – This section does
not provide insulation. This area includes the lower
steel portion of the upper boom, knuckle, and the

steel upper portion of the lower boom and
compensation link (when applicable).
Area 4, Lower Boom Insulating Section – (When
so equipped) This section provides insulation**
between the intermediate structure (Area 3) and the
vehicle when clean and properly maintained.
Area 5, Lower Structure – This area does not
provide insulation. This area includes the steel lower
portion of the lower boom and compensation link
(when applicable), turret, lower controls, pedestal,
and the vehicle.
* On VST and T-Series models not supplied with an
upper insulated section decal, the insulated section
begins 11 inches below the center of the platform
pivot.
** Insulation properties are defined by ANSI A92.2
