The following rules apply to all use of crane and hoist operations at Berkeley Lab.
Whoever needs to move a load must:o First determine the value of the load and consequences of a failed moveo Determine if the load needs to be moved by a craneo Determine who can operate the crane
-
7/29/2019 Cranes Hoisting and Rigging
9/25
Loads meeting the definition of High-Consequence/High-Value Lifts/Moves or otherrestricted operations (see Work Process D) require more detailed planning and may
require the lift to be performed by the Facilities Division Riggers.
Operators must be authorized by Line Management to use cranes. Operators must be authorized by the Crane Manager to use a specific crane. Operators must be qualified to use the type of crane they intend to use. Operators must plan each lift, taking into account the path of travel to avoid contact
with personnel and objects.
Loads meeting the definition of High-Consequence/High-Value Lifts/Moves or otherrestricted operations (see Work Process B) require more detailed planning and may
require the lift to be performed by the Facilities Division Riggers.
Operators must inspect the crane and associated rigging prior to using the crane. Cranes and rigging found to be deficient must be taken out of service, and cannot be
used unless repaired and recertified by the Facilities Division Crane MaintenanceVendor.
Cranes and rigging must be rated to lift the intended load; no load (including rigging,devices, and lifting fixtures) may exceed the limits of the crane and rigging. If an
employee is unsure of the weight of a load, or if the load weight exceeds 75% of the
cranes capacity, contact the Facilities Division Rigging Supervisor for assistance.
Crane testing by the Facilities Division Crane Service contractor is the only exception
to this rule.
Operators are responsible for ensuring that the load is properly rigged to avoidshifting during the lift. Test lifts of less than one foot from the ground to check forload shifting are permitted.
All personnel who are operating a crane or hoist, are participating in the lift, or arelocated within 15 feet of the vertical plane of the load where the undercarriage of
the bridge is more than 12 feet from the ground must wear hard hats. Post or
barricade the area as needed.
Sturdy work gloves must be worn when handling wire rope or loads with rough orsharp edges or splinters.
Suspended Loads
These rules apply to operators of suspended loads:
Test brakes under load when load is 80% of the crane's rated load. Raise the load afew inches and apply the brakes.
-
7/29/2019 Cranes Hoisting and Rigging
10/25
Ensure loads are never lowered below the point where less than two full wraps ofrope remain on the hoisting drum.
Do not allow hoisting chains or ropes to kink or twist, or to wrap around the load. Attach the load to the load block hook ONLY by means of slings or other approved
devices; NEVER wrap the hoist rope around the load. Ensure loads are well secured and properly balanced in the sling or lifting device
before it is lifted more than a few inches.
Avoid suddenly accelerating or decelerating the moving load. Do not allow the load to contact obstructions. Do not allow loads moved with any material-handling equipment to pass over any
personnel.
Select the load path to eliminate the possibility of injury to employees should thematerial-handling equipment fail.
Do not permit work on suspended loads. Rest the load on adequate cribbing if itneeds to be worked on.
Never leave a suspended load unattended nor leave the controls while the load issuspended. Lower the load to the floor or the working surface or onto cribbing, and
secure the material-handling equipment before leaving the load unattended.
Component Failure or Unintended Movement
If any component fails during a lift, or if there is any uncontrolled or unintended motion of
the load during the lift, the lift must be terminated immediately in the safest manner
possible. Immediately notify the Crane Manager of the component failure. Contact EH&S
and the Facilities Division Rigging Supervisor.
Lifting may only resume after the failure or unintended motion has been investigated, and
appropriate corrective steps have been implemented.
Securing Cranes
Any electric-powered crane, when not attended by a qualified operator during an entire shift
and off-hours, must be secured by locked controls or equivalent means to prevent access to
the crane, such as locking the doors or locking up radio controls. Only the Crane Manager or
another qualified and authorized user of the secured crane may have control of the locking
mechanism.
Work Process B. Procurement and Maintenance of Cranes and Hoisting and Rigging
Equipment
-
7/29/2019 Cranes Hoisting and Rigging
11/25
Approval from the Facilities Division Maintenance Manager must be obtained before
purchasing hoists or cranes, or lifting equipment such as shackles, clevises, wire rope or
fabric slings, or spreader bars (strongbacks). Procurement will not process any purchase
orders for such equipment without this approval. The preferred method for ordering hoisting
and rigging equipment is to request that the Facilities Division Maintenance Manager ordesignee (ext. 7667) order the items, using an account number provided by the requester.
If used equipment is procured, it must be inspected and certified to meet all applicable
standards in force at the time of the acquisition.
For Berkeley Labdesigned and/or fabricated lifting devices, see Work Process G.
When equipment is received, the recipient must contact the Facilities Division Crane
Maintenance Vendor (ext. 7667 orcranesafety@lbl.gov) to have the equipment inventoried
for routine inspection and maintenance. All hoisting and rigging equipment (except when
impractical, e.g., shackles, swivel lifting rings, etc.) used at the Laboratory must have a
Laboratory proof-load tag attached with a current inspection sticker. The user, supervisor,
and operator are directly responsible for verifying the presence of current, proper tagging of
hoisting and rigging equipment prior to use.
Work Process C. Authorization and Qualification to Use Cranes
All crane use must be authorized by an employees Job Hazards Analysis (JHA), and by the
Crane Manager for the particular crane(s) to be operated. The Crane Manager is a qualified
crane operator who has been designated as the individual responsible for the safe operation
of a specific crane. Before operating a crane in an area for the first time or in a new
application, employees must discuss the proposed crane use with the Crane Manager and
obtain approval. The Crane Manager will determine whether the operator is familiar with the
controls for that particular crane and knows how to properly rig loads, and will verify that
crane use will not conflict with other operations in the area.
Cranes may also be operated by qualified Crane Service personnel who have been
authorized by either a JHA (for the on-site Facilities Division Crane Maintenance Vendor) ora SWJHA, and have been subcontracted to install, maintain, or repair cranes.

7/29/2019 Cranes Hoisting and Rigging
12/25
The operation of overhead cranes and hoists is restricted to trained personnel who have
completed Berkeley Labrequired training, and who have been certified in accordance with
the requirements of this chapter. This includes the operation of cranes without a load for
any reason. Requirements for operating mobile cranes can be found in Work Process F.
To become certified for operating cranes up to a two-ton capacity, the following
requirements must be met:
All prospective operators of cranes and hoists up to a two-ton capacity must meetthe health requirements that would entitle them to operate a motor vehicle in the
state of California. Individuals who do not hold a valid drivers license must be
examined and approved by Health Services at Berkeley Lab.
The prospective operator must complete EHS0210, Crane/Hoist Operator 2 Tonsor Less. This course includes hands-on instruction, and a certificate will be issued
after the successful completion of the course.
Note that crane and hoist operators with this certification may NOT operate cranes
or hoists with a capacity of greater than two tons to lift loads of less than two tons
or without any load.
To become certified for operating overhead cranes or hoists with a capacity of greater than
two tons, the following is required:
All prospective crane operators must complete an application and must pass amedical examination and/or review of medical information on file at Health Services
prior to training. The application must identify a qualified crane operator who will
provide hands-on instruction and close supervision during an initial training period.
The supervisor and the operator who will provide the instruction must sign the
application and agree to the initial training. If the prospective operator has prior
experience operating cranes, he or she may be examined and certified without an
initial training period.
The prospective operator must complete EHS0206 (Crane/Hoist Operator Greaterthan 2 Tons). Upon completion ofthis classroom training, a learners permit is issued
when needed, and the individual may operate cranes and hoists under the direct
supervision of the operator identified on the application. The learners permit will
expire no later than 60 days from the date of issuance.
When the prospective operator is ready, he or she may contact an overhead-cranepractical-examination instructor to be examined on the operation of the specific
-

crane to be operated most frequently. A list of qualified overhead-crane practical-
examination instructors is maintained by the EH&S Division Training Group.
Crane operators must renew their training every three years, and must be medically
recertified every three years.
Work Process D. Restricted Operations
High-Consequence/High-Value Lifts and Moves
The customer (i.e., the manager who requires the items to be moved) or a program
organization designates parts, components, assemblies, or lifting operations as high-
consequence/high-value lifts/moves, because the effect of those items falling from the
crane, or colliding with other objects, could:
Cause damage in excess of $500,000o This requirement does not apply to routine movements of shielding blocks
performed by members of the professional rigging crew.
Cause significant work delay or programmatic impact Cause undetectable damage resulting in future operational or safety problems Result in significant release of radioactivity or other undesirable conditions Present a potentially unacceptable risk of personnel injury or property damage
In addition, any lift/move that requires the simultaneous use of both the main and auxiliaryhoists of a given crane or the simultaneous use of two cranes must be considered a high-
consequence/high-value lift/move.
High-Consequence/High-Value Lift/Move Requirements
A detailed, step-by-step procedure in the form of an Engineering Note must be prepared for
each high-consequence/high-value lift/move. This requirement covers lifts and moves
performed with forklifts or cranes. An Engineering Note template may be obtained from the
Engineering Division athttps://dcc.lbl.gov/dcc/EngNotes.php. While high-
consequence/high-value lift procedures are customarily prepared for one-time use, general
high-consequence/high-value lift procedures may be employed to accomplish routine,
recurrent high-consequence/high-value lift operations. For example, a general high-
consequence/high-value lift procedure may be applied to lift shielding blocks or a frequently
lifted item. Examples can be found through the search page of the Berkeley Lab Engineering

in the Title 3 field).
The customer, i.e., the Laboratory manager who requires the item to be moved, is
responsible for preparing the high-consequence/high-value lift/move Safety EngineeringNote. The customer can discharge this responsibility by indicating on the Facilities Work
Request that the scope of work should include preparation of the Engineering Safety Note
and management of the move. It is the responsibility of the customer to notify all personnel
whose approval is required early in the process. See High-Consequence/High-Value Move
Lift/Move Approval below.
Approvers have special expertise and are available to provide guidance during the design of
the lifting procedure. Please allow sufficient time for the review-and-approval process. There
is no charge for the review-and-approval process.
The procedure must contain the following:
Identification of the item to be moved Identification of the Laboratory manager or engineer who is responsible for planning
the lift
Identification of the rigging supervisor or designated qualified rigger (other than theequipment operator) who will be the Person In Charge (PIC) of all aspects of the lift
while the load is suspended
Special precautions Weight of the item Total hook load (all component parts of the item plus tackle and load-measuring
devices)
Determination of the center of gravity A list of each piece of equipment and each accessory (e.g., slings, spreader bars,
yokes) to be used in the lift
Each accessory must be identified by type and rated capacity If a portable item to be used has no manufacturers serial number, a Berkeley Lab
identification number must be assigned and affixed to the item
Surveillance procedures, checkpoints, and estimated instrument readings (if used)must be listed to enable confirmation that the lift is proceeding as planned
Calculation of stresses to be generated in the item during lifting and determination ofthe adequacy and proper labeling of the attachment points of the item to be lifted.

16/25
The EH&S Division DesigneeAll reviewers should be consulted early in the process to ensure their concerns are
addressed, avoiding the need for later revisions to the procedure.
Unanticipated conditions may require on-the-spot changes of the lift procedure. Approvers
of the lift procedure should be present during the lift or at least immediately available to
approve changes. Changes must be recorded on the procedure and initialed by all available
approvers before they are implemented.
Personnel Participating in High-Consequence/High-Value Lifts/Moves
Each person involved in a high-consequence/high-value lift/move must be familiar with the
procedure before beginning work. A pre-lift meeting with all participating personnel must be
held before the lift. All participating personnel must initial the procedure sign-off sheet to
verify that they are familiar with the procedure.
Cab-Operated Cranes
Operation of cranes from a cab is restricted to professional riggers. The following rules apply
to cab-operated cranes:
Do not store personal belongings (including necessary clothing) in a manner thatinterferes with operations.
Store other necessary equipment (tools, oil cans, waste, extra fuses, etc.) in thetoolbox. Do not store equipment loosely in or about the cab.
Heavy Lifts
Heavy lifts should be made by the professional rigging crew that performs such work
routinely. Where there is a need for other personnel to lift loads over 10,000 lb., and lifts
exceeding 75% of the cranes maximum capacity, the proposed lift must be reviewed with
and approved informally by the supervisor of the professional rigging crew or his or her
designee.
Tilting Loads
Using a crane to tilt a load (standing up a load that is lying down or vice versa) carries a
significant risk of shock-loading the crane or losing control of the load. When such
operations involve loads that exceed 50% of the rated capacity of the crane, they must be
-

reviewed by and may be performed only with the informal approval of the supervisor of the
professional rigging crew or his or her designee. If two hooks are required to tilt the load,
follow the high-consequence/high-value lift procedures listed above.
Work Process E. Mobile Cranes
The operation of mobile cranes is restricted to those who have been certified as competent
and qualified mobile crane operators by an independent certification agency. The Facilities
Division Riggers have authorized and qualified mobile crane operators.
Mobile crane operations for construction have additional requirements, which are found in
PUB-3000, Chapter 10. For the purpose of the Berkeley Lab Cranes, Hoisting, and Rigging
Program, small truck-mounted jib cranes with capacities of less than 2 tons are not
considered mobile cranes. Mobile crane operations are conducted in accordance with all
applicable Occupational Safety and Health Administration (OSHA) (and Cal/OSHA for
construction) requirements.
Any mobile crane, when not attended by a qualified operator during an entire shift or during
off-hours, must be secured by locked controls or equivalent means to prevent access to the
crane, such as locking the doors or locking up radio controls. Only the Crane Manager or
another qualified and authorized user of the secured crane may have control of the locking
mechanism.
Work Process F. Crane Inspections
Each crane or hoist must be inspected by a qualified crane operator before use, during any
given work shift. The inspection can be documented either on a tag attached to the crane
controls or in a log that is kept with the key to the crane controls. If the crane is not used
during any shift, it does not need to be inspected. However, each crane must be given a
documented operator inspection at least once a month whether or not it is used during the
month of the inspection. Inspection tags will be collected by the Facilities Division Crane and
Hoist Services Contractor and kept on record. Where applicable, crane inspection logs will
be reviewed by the Crane and Hoist Services Contractor. Typical crane inspection checklistsare shown inAppendix Aof this PUB-3000 chapter.
All other required equipment inspections and tests are performed by the Facilities Division
Crane and Hoist Services Contractor. Equipment and the frequency of equipment
inspections and tests are listed in a Facilities Division database as required by applicable
http://www.lbl.gov/ehs/pub3000/CH10.htmlhttp://www.lbl.gov/ehs/pub3000/CH10.htmlhttp://www.lbl.gov/ehs/pub3000/CH27.html#27.ahttp://www.lbl.gov/ehs/pub3000/CH27.html#27.ahttp://www.lbl.gov/ehs/pub3000/CH27.html#27.ahttp://www.lbl.gov/ehs/pub3000/CH27.html#27.ahttp://www.lbl.gov/ehs/pub3000/CH10.html -

regulations and/or standards. Facilities Division Crane Maintenance Vendor work orders are
automatically generated monthly and are based on information in the database.
Work Process G. Rigging and Other Below-the-Hook Devices and Fixtures
The crane operator is responsible for verifying that the load is properly rigged. The crane
operator must also take the following precautions when performing work:
Thoroughly inspect rigging before use (document the inspection on the Daily CraneInspection Tag).
Remove defective rigging from service. DO NOT USE and DO NOT REPAIR defectiverigging.
All other required rigging inspections and tests are performed by the FacilitiesDivision Crane and Hoist Services Contractor. The frequency of these various
inspections and tests are detailed in Facilities Division work orders.
Only use slings in accordance with the manufacturers recommendations. Use engineered attachment points and standard hardware (swivel lift rings, shackles,
and nylon slings) wherever possible.
Verify that all slings and hardware are rated for more than the expected load and areappropriate for the intended type of load and configuration.
Verify that all slings and special lifting hardware have current Berkeley Labinspection tags.
Never shorten slings with knots, bolts, or other makeshift devices. Never load rigging in excess of its rated capacities. Use padding to protect natural fiber or synthetic slings from damage (e.g., contact
with sharp edges).
Verify loads are balanced to prevent slippage (e.g., when using a basket hitch). Remove slings from a load when the load is not resting on the sling. Contact the EH&S Crane and Hoist Subject Matter Expert (cranesafety@lbl.gov) or
the Facilities Division Crane Maintenance Vendor (ext. 7667) before rigging is used in
any manner or environment (e.g., used in close proximity with corrosives or
degrading chemicals, operated in temperature extremes of20F or +180F, etc.)
that may compromise its construction or strength.
Inspection and Testing of Lifting Devices
Each division is responsible for the safety and pre-use inspection of its lifting devices
(such as screw pin shackles, hoist rings, commercial equipment, etc.) and for its lifting
fixtures (such as spreader bars, special slings, equipment designed at Berkeley Lab, etc.).

Berkeley Lab proof-load tags and inspection stickers must be current, where
applicable. Special-purpose lifting fixtures must be marked with a Laboratory equipment
number and labeled to identify applicable Engineering Safety Notes for fixture design and/or
high-consequence/high-value lifts/moves.
All lifting fixtures designed at the Laboratory must be proof-tested to twice their maximum
rated loads before being placed in service. A Non-Destructive Examination (NDE) is required
after the proof test. The exact type of NDE must be specified in the Engineering Safety Note
for the lifting fixture. The rated capacity must be marked on the lifting fixture so that it is
clearly visible to the equipment operator.
Order commercially available lifting fixtures through the Facilities Division Maintenance
Manager or Designee to assure they are ordered with a certificate of proof load testing. For
commercial lifting fixtures without certified load ratings, an Engineering Safety Note must
be written to determine the safe load capacity and furnish guidance for load testing.
Where the lifting fixture cannot be proof-tested because it is an integral part or component
of the experimental device, equivalent alternative safety precautions acceptable to the
Mechanical Engineering designee must be described in the Engineering Safety Note, which
delineates the lift procedure.
All lifting device pins of 5 cm (2 in.) in diameter or larger must have a magnetic-particle
inspection before they are placed in service. These pins are always part of a lifting device or
fixture. Make arrangements with the Facilities Division Crane Maintenance Vendor, ext.
7667, or theWork Request Center, ext. 6274, to have lifting fixtures inspected.
Active lifting devices and fixtures must be examined by an NDE at least once every four
years (or upon request), using magnetic-particle detection or other appropriate methods.
Make arrangements to have lifting fixtures inspected with the Facilities Division Crane
Maintenance Vendor, ext. 7667, or contact theWork Request Center, ext. 6274. Records
must be maintained by the Facilities Division and NDE organizations. Inactive lifting devices
and fixtures must be clearly marked STOP: DO NOT USE, and must be load tested and
certified prior to renewed use.
The Responsible User must ensure that:
Proof-testing is performed by the Facilities Division on all lifting fixtures designed atthe Laboratory, before they are placed in service
Adequate test records are kept

Lifting devices and fixtures are used and maintained correctlyThe Responsible Designer must obtain design approval by means of an Engineering Safety
Note, as described below. For equipment designed at the Laboratory, the Responsible
Designer must provide the user with the information required to operate the lifting device orfixture safely. The Facilities Division will provide a test report to the user upon request.
Design of Lifting Fixtures
A qualified engineer must be designated to be responsible for the design, fabrication, and
testing of lifting fixtures not purchased commercially. The actual physical testing usually will
be performed by the Facilities Division in accordance with the written test procedure
specified by the Project Engineer.
All lifting fixtures designed or fabricated at the Laboratory must be covered by an
Engineering Safety Note. The Engineering Safety Note must include the calculation of lifting
fixture stresses and deflections, and must be reviewed and approved by:
The Responsible Designer Customer Management The Engineering Division Mechanical Engineering Department designee The Facilities Division Planning, Design & Construction Department, Structural
Engineering Group designee
The Facilities Division Plant Operations Department Rigging Supervisor The EH&S Division designee
The design stress for lifting fixtures or lifting attachment points must not exceed one-fifth
the ultimate strength of the material at its operating temperature. If welded fabrication is
used, the design stress must take into consideration any weakening effects of welding, such
as those that occur in aluminum alloys.
If practical, avoid welding in the fabrication of lifting fixtures. If welding must be used,
design and fabrication in conformance with the latest standards of the American WeldingSociety (AWS) are required. Careful, thoughtful design and follow-up are required.
Follow these rules for all lifting fixtures:
All welds in lifting fixtures must be certified welds, performed by certified welders,and inspected and certified by certified weld inspectors.
-
7/29/2019 Cranes Hoisting and Rigging
21/25
If at all possible, do not allow welds to be subjected to tearing loads. Stresses inwelds must be substantially uniform.
Where possible, design lifting fixtures so that the main loads are carried only bystructural members, plates, or shear pins rather than by welds. Examine this
possibility carefully. Proof-test lifting fixtures to twice the maximum rated load. Follow by a
nondestructive examination. X-ray primary load-carrying welds and welds in
tension, or perform other suitable subsurface crack-detection examinations.
The screw-thread engagement required for conservative development of the fullstrength of a screw fastener depends upon the screw-fastener material and the
material of the threaded member.
o If the fastener is made of the same material as the female threaded member e.g., a low-carbon steel bolt and a hole threaded into low-carbon steel
an engagement of at least 1 diameters is required.o A hardened steel screw (Allen screw) in mild steel requires at least 2
diameters of engagement.
o A low-carbon screw fastener, threaded into a tapped hole in aluminum alloy,copper, or cast iron must have a threaded engagement of 1 diameters.
o Other material combinations must be approved by the Mechanical EngineeringDepartment designee.
Safety hoist rings may be used to make lifts up to their rated load whenscrewed 2 hoist-ring bolt diameters into materials such as aluminum alloy,
copper, or cast iron. When special high-strength bolts are required, test any bolt used as part of
Laboratory-designed lifting fixtures or pickup devices to two times its rated load. A
crack-detection inspection must be performed after the load test to ensure integrity.
Try to maintain a supply of tested bolts in the event that one is lost, or better yet, to
have the bolt on a permanent lanyard. Once a lifting device or fixture has been
delivered to the user, the user is responsible for ensuring that the proper bolt is
inserted to the proper depth and correctly torqued.
When the lifting fixture also serves as a shipping container or frame holding theexperimental device during transport, specify tie-down requirements and otherspecial shipping requirements to ensure the integrity of the experimental device,
e.g., anticipate flexing of the truck bed, acceleration due to bumps and potholes,
and/or vibration.
Label lifting attachment points adequately to ensure proper and safe use of thefixture.

Any deviation from these rules requires equivalent alternative safety measures that have
been explicitly approved by the Mechanical Engineering Department designee.
Single-Bolt Pickup Devices
When equipment is designed to be crane-lifted at a single point with a single-bolt pickup
device, the vertical lifting load through the screw thread of the bolt must be in line with the
axis of the bolt so the load will remain level when it is lifted. With this bolt alignment, the lift
will be through the center of gravity and will be safer, since the load will not tilt or kick out
when it is lifted. A single-bolt pickup device must be used, such as a safety hoist ring or an
equivalent in-house device that is carefully designed and maintained. The threaded
engagement must comply with the requirements in the Design of Lifting Fixtures section,
above.
When a load is to be crane-lifted by slings from a crane hook through two, three, or four
pickup points located at the corners of the load, and without the use of a spreader bar, the
forces at the lift points are nonvertical. Again, a single-bolt pickup device, such as a safety
hoist ring or an equivalent in-house device that is carefully designed and maintained must
be used at each pickup point.
Eyebolts without shoulders are not allowed for use in lifting any load. Eyebolts with
shoulders are permitted for lifting loads when the following conditions are met:
These devices shall be rated for the load and approved for the application, e.g., acarbon steel eyebolt rated at 1,500 lb. Threaded into a carbon steel block.
The load is in line with the axis of the eyebolt, and side loads are minimal (aspreader bar may be required).
The thread engagement is at least 2 bolt diameters. The eyebolts are torqued to amanufacturers recommendations, if given, or another reasonable torque
substantially greater than finger tight. Angled sling usage is allowable if a
manufacturers recommendations for load reduction are given.
The use of unrated eyebolts or eyebolts in applications not specifically approved by themanufacturer must be specifically approved by an Engineering Safety Note.
