Personnel Basket Manual which addresses safety,
inspection, testing, operation, installation, and lubrication.
The following information is for machines that are not Dual
Rated.
The American Society of Mechanical Engineers published
the American National Standard entitled, Personnel Lifting
Systems, ASME B30.23:
This Volume establishes the design criteria, equip-
ment characteristics, and operational procedures
that are required when hoisting equipment within
the scope of the ASME B30 Standard is used to lift
personnel. Hoisting equipment defined by the
ASME B30 Standard is intended for material han-
dling. It is not designed, manufactured, or intended
to meet the standards for personnel handling equip-
ment, such as ANSI/SIA A92 (Aerial Platforms).
The equipment and implementation requirements
listed in this Volume are not the same as that estab-
lished for using equipment specifically designed
and manufactured for lifting personnel. Hoisting
equipment complying with the applicable Volumes
of the ASME B30 Standard shall not be used to lift
or lower personnel unless there are no less hazard-
ous alternatives to providing access to the, area
where work is to be performed. The lifting or lower-
ing of personnel using ASME B30-compliant hoist-
ing equipment is prohibited unless all applicable
requirements of this volume have been met.
This standard is consistent with the U.S. Department of
Labor, Occupational Safety and Health Administration
(OSHA) regulations for Construction that state, in
29CFR1926.1431:
General requirements. The use of equipment or
derrick to hoist employees on a personnel platform
is prohibited, except when the erection, use, and
dismantling of conventional means of reaching the
worksite, such as a personnel hoist, ladder, stair-
way, aerial lift, elevating work platform or scaffold,
would be more hazardous or is not possible
because of structural design or worksite conditions.
Additional requirements for equipment operations are stated
in ASME B30.5, Mobile and Locomotive Cranes, ASME
B30.8, Floating Cranes and Floating Derricks, and in OSHA
regulations 29CFR1910.180 for General Industry and
29CFR1926.1431 for Construction.
Use of National Crane equipment to handle personnel is
acceptable, provided:
• The requirements of the applicable national, state and
local regulations and safety codes are met.
• A determination has been made that use of equipment
to handle personnel is the least hazardous means to
perform the work.
• The equipment operator shall be qualified to operate the
specific type of hoisting equipment used in the
personnel lift.
• The equipment operator must remain at the equipment
controls at all times when personnel are off the ground.
• The equipment operator and occupants have been
instructed in the recognized hazards of personnel
platform lifts.
• The equipment is in proper working order.
• The equipment must be equipped with a boom angle
indicator that is visible to the equipment operator.
• The equipment's Load Chart is affixed at the operator’s
station and readily accessible to the operator. The total
weight of the loaded personnel platform and related
rigging shall not exceed 50 percent of the rated capacity
for the radius and configuration of the equipment.
• The equipment is level within one percent of level grade
and located on a firm footing. Equipment with outriggers
shall have them all deployed following manufacturer's
specifications.
• The equipment's Operator Manual and other operating
manuals are at the operator’s station and readily
accessible to the operator.
• The platform meets the requirements as prescribed by
applicable standards and regulations.
• For hoist rope suspended platforms:
- The equipment is equipped with a hook that can be
closed and locked, eliminating the throat opening.
-
The equipment is equipped with a functional anti-
two-block device.
- The platform is properly attached and secured to the
load hook.
• For boom mounted platforms:
- On a equipment equipped with a boom mounted
personnel platform, use only a platform approved by
National Crane.
- The platform is properly attached and secure.
To avoid death or serious injury:
• NEVER use this equipment for bungee jumping or any
form of amusement or sport.
• NEVER handle personnel on the loadline unless the
requirements of applicable national, state and local
regulations and safety codes are met.
• NEVER permit anyone to ride loads, hooks, slings or
other rigging for any reason.
• NEVER get on or off a moving equipment.
• NEVER allow anyone on the hoist access platform
while traveling.
