Overhead Lifting—What is it?
What is overhead lifting?
The process of lifting which would elevate a freely suspendedload to such a position that dropping the load would presentthe possibility of bodily injury or property damage.
“Overhead lifting is a special event.”
Risk is created every time we lift a load off the
ground.

Risk is . . .

How Can You Manage Risk?
Risk management is a comprehensive set of actions that reduces the risk of a problem, a failure an accidentfailure, an accident.
Risk Management Means . . .
We must:PlanEveryLift
What inspections are required for hoists and cranes?
Daily (each shift) visual and operational inspection by the operator.Monthly inspection (minimum) withMonthly inspection (minimum) with signed reports by a qualified person.Periodic inspections (minimum once per year) with signed reports by a qualified person.

What inspections are required for slings?
Each lift, before use, by the operator.Each day, before use, by a competent personcompetent person.Annually by a qualified person.
What inspections are required for below-the-hook devices?
Each lift, before use, by the operator.Daily by the operator.A ll b lifi dAnnually by a qualified person.
What is a Qualified Person?
“A person who, by possession of a recognized degree or certificate of professional standing in an applicable field, or who, by extensive knowledge, training and experience, has successfully demonstrated the ability to solve y yor resolve problems relating to the subject matter and work.”

How It Works
• RFID handheld scans the ChipID (or type in serial #) to display corresponding asset details, schedules and inspection forms
• Passive: chip has no battery and is intrinsically safe• Chip sizes: 0.5” x 0.1” and up• Read/write range: 2 inches

What are the Steps in our lifting plan?our lifting plan?
Who is Responsible (competent) for this Rigging?
Communications established?
Is the Equipment in Acceptable Condition?
Appropriate type?
Is the Equipment in Acceptable Condition?
Proper Identification?
Are the Working Load Limits Adequate?
Capacity of Gear Known?
Are the Working Load Limits Adequate?
What is the weight of the load?What is the center of gravity?
•5
The Center of Gravity
Center of gravity is directly below the load hook
dand
connection to the load is above center of gravity
Are the Working Load Limits Adequate?
Are the slings padded against sharp corners?
Types of Wear Pads Are the Working Load Limits Adequate?
What is the sling angle?

Are the Working Load Limits Adequate?
Is the load rigged to the center of gravity?
Will the Load be Under Control?
Is the hitch appropriate?
Selecting Slings & Hitches for Load Control
Select the sling to be used considering:The hitch to be usedThe load that will be appliedThe rigging environment
Choker Hitch
Single Leg and Load Control
They provide good control only for simple loadsDo not use hitch for lifting loose materials, long material, any load that can tip
Basket Hitch and Load Control
For more contact with the load use a double wrap basket hitch
Do not overlap at the bottom of the load
•7
Choker Hitch and Load Control
A choker hitch does not provide 360 degree contact with the surface
A block of wood between hitch and load improves grip and angle of choke
Load Under Control?
Slings capture center of gravity?Load lift level?Load stable?Load stable?Tag line required?
Will the Load be Under Control?
Is the hitch appropriate?Tag line needed?
Are There any Unusual Loading or Environmental Conditions?
Is there any possibility of fouling?Clear of personnel?
Will the Load be Under Control?
Wind, temperature, other?

Cranes are Designed for Vertical Lifts Only
Side pulling and end pulling are improper lifts.
Lifting & Moving of Load
Pay attention.Perform lift so if there is a failure--no one would get hurt
Slowly raise load--to minimize swing. Use proper hand hurt.
Keep hands clear--no pinch points.Slowly raise hook block.
p psignals--when necessary.“Respect The Load”
I P CIf you practice good risk
management . . .
. . . you will take the risk and the dice roll out of your
crane operation.p
