Most hoists and cranes are designed and intended for handling materials and not personnel.
The crane or hoist
is only to be used to handle personnel if it can be shown there is no less hazardous way of carrying out
the job.
In these situations, all safety precautions must be strictly adhered to. BRADEN recommends adherence
to the latest revision of API 2D (RP 2D) and/or ANSI/ASME standard B30.5 and/or OSHA and/or other applicable
standards for your application. It is important that you obtain a copy of all applicable safety standards, and that
you read and understand them prior to using the hoist.
In addition to, or in conjunction with, the applicable
standards, BRADEN requires:
• The hoist
MUST
be maintained in accordance with BRADEN recommendations in Braden publication PB-308
and the service procedures in this Installation, Maintenance and Service Manual.
•
When handling personnel, the allowable line pull will be limited to 30% of the hoist rated line pull.
This
reduction increases the hoist design factor from 3:1 to 10:1, approximately. Example: a hoist rated at 15,000
lbs. on the first layer will be rated at 15,000 x 0.3 = 4,500 lbs. on the first layer when handling personnel.
•
Personnel are only permitted to ride in an approved personnel platform
as described in API, OSHA or
ANSI/ASME standards.
• The crane
MUST
be in good working order and equipped with all required safety equipment, including an anti
two-blocking device or warning signal and a boom angle and length indicator. Two-blocking occurs when the
load block or hook assembly comes in contact with the upper block or point sheave assembly and often results
in damage to the wire rope, rigging and/or hoist.
• Personnel being lifted or supported shall wear safety belts with lanyards attached to designated points unless
lifting over water. If lifting over water, provide approved personal flotation devices (PFD's).
• The lifting and supporting shall be made under controlled conditions and under the direction of an appointed
signal person.
• The operator and signal person shall conduct a test lift, without personnel in the personnel platform, to verify
adequacy of the crane footing or support. The crane outriggers, if so equipped, must be fully extended and
properly set.
• Cranes shall not travel (move locations) while personnel are on the personnel platform.
• The platform must be landed or tied off, and all brakes set before personnel enters or exits.
