P E R S O N N E L PLATFORMS.
Handling of personnel from the boom is not authorized except with equipment
furnished and installed by Grove Manufacturing Company. Upon approval by
Grove of any personnel handling device, the following minimum safety re-
quirements shall be strictly observed:
NOTE
Platform as used herein is defined as any attach-
ment made to a crane boom which is intended to
elevate or position people and includes work
baskets, cages, or other devices for handling
personnel.
- Whoever mounts a platform upon a crane shall perform stability tests
before the unit is placed in operation. Thereafter, the installer shall
perform a thorough visual inspection of the crane and platform for
evidence of defects, deformation of any component, hydraulic leaks,
and other items. All defects noted shall be corrected prior to handling
personnel.
- The installation of platform(s) to the main boom or any boom exten-
sion (appurtenance) firmly secured by mechanical means (i.e., pins,
bolts, etc. ) to the main boom shall require the crane to be checked for
stability. If such an arrangement cannot meet stability requirements
of ANSI A92.2 with the platform positioned at its furthest operating
radius and positioned in the least stable direction (i.e., over the side,
end, etc.), then a means to warn the operator when he has reached the
maximum operating radius must be supplied. Attachment of platform(s)
to jibs supported by wire rope (e.g., pendants, backstays, etc. ) is
strictly prohibited.
- Materials shall not be handled or lifts performed when personnel are
occupying the platform.
- Locks and brakes provided on the platform shall be set when the plat-
form is in working position and personnel are at their work location.
