Introduction
• Lifting is very common in the construction industry as a method
for material transfer. Through mechanical means such cranes,
lifting equipment and manual handling.
• The risk of injury can be reduced through training and application
of correct lifting & handling techniques.

Lifting plan
Lifting plan must include as a minimum;
 Position of item to be lifted and lifting equipment (Pick up and set down)
 Weight and configuration of item to be lifted
 Radius of lift
 Calculated capacity
 Details of lifting equipment
 Lifting restrictions
 Ground loads

Lifting plan
Points to be consider during the lifting plan
• Site inspection
• Know the load details
• Selection crane and slings
• Necessary certifications (TPI, Load chart, Operator certificate
and….ect)
• Load transportation or load radius/Distance
• Calculation the SWL
• Inspection crane and lifting Equipment
• Barraction lifting area
• Rigger avaliabe
• Supervisor available
• start-up

Calculation the SWL
SWL- (Totally Load weight/selection load ) * 100% =
e.g we have Cravans and the weight of load with lifting tools equal
4.2 ton and the Dimension of Caravan 6000.3000.3500mm kindly
find the SWL.use this load chart.
Note- The cravans will installation on foundation have high 30 cm.

LOAD CHART- The manufacturer gives it with each crane to determine
the crane load, with the three factors (Boom length, crane tilt angle
radius) varying from one crane to another.

Rigging
• Skilled rigger.
• Only persons qualified as riggers.
• A rigger must have safe act
• A lifting plan above 40 tons.

Types of slings
➢ There are six main types of Slings
• CHAINS
• WIRE ROPE SLINGS
• FIBER ROPE
• SYNTHETIC WEB SLINGS
• MATAL MESH WIRES
• NAUTRAL FABRIC ROPE

CHAINS
• Chains are widely used because of their strength and
ability to adapt to the shape of the load.

Rigging
WIRE ROPE SLINGS
• Solid wire consists of several individual strands that are
twisted together to form Strands: The strands are twisted
to form the rolls that wrap around an internal wire. The
wire.
The steel wire is manufactured with a safety factor (Design Factor) of 5:1, meaning that the wire designed to lift a
maximum load of 2 tons is designed and tested to withstand 10 tons in order to withstand the harsh service
conditions.

Rigging
FIBER ROPE
• Fiber ropes are widely used in some types of lifting due
to their flexibility, ability to adapt and fit the shape of
the load and hold it, in addition to not distorting the
load.
INSPECTION FIBER ROPE
• The outer surface is first inspected for dry, wounded, cut or discolored
parts.
• The wire core is then inspected and the internal color should be the
same as the new wire, taking into account the presence of any
powder-like substance inside the wire as this indicates that the wire
has been exposed to severe wear.
• Finally, scratch the wire with your fingernails in case materials come
out of the wire easily, which means that the wire has been exposed to
chemicals and must be removed immediately.

Rigging
SYNTHETIC WEB SLINGS
• Industrial wires are widely used in lifting operations and
are made of different materials such as nylon, dacron,
and polyester. Among its benefits are:
INSPECTION WEB SLINGS
• Acid or burns to the wire
• Melting or tearing of any part of the wire surface
• Any cuts, tears or holes in the wire
• Tearing or cutting of the wire stitching
• Tearing of the stitches
• Any cut that exceeds the permissible percentage
according to the manufacturer’s recommendations

Lifting and Rigging hazards
Crane hazards and their causes
• Contact with high voltage cables
• Miscarriage due to poor implantation
• Crane overturning
• Crane arm collapse
• Mechanical parts breakdown
• Unstable ground
• Lack of communication and guidance Lack of training
• Insufficient maintenance and inspection
• Lifting during winds greater than 32 km

An unstable load,
lack of
communication, lack
of training, and
inadequate
maintenance or
inspection are major
contributors to crane
accidents.

• Operators or others working in the area can be victims
to “struck by" and "caught in" injuries.
• Contact with power lines causes many accidents.
• A competent person must inspect a crane regularly to
insure it is in proper order.
• Planning and training reduces accidents.
Summary
LIFT SAFELY AND LIVE HAPPY

DW-HSE-TM010 48
Q: What is rigging?
A: Rigging is the process of lifting and moving heavy loads using cranes,
hoists, and other equipment.
Q: Why is rigging safety important?
A: Rigging can be dangerous and requires proper training, equipment, and
procedures to avoid accidents. Proper rigging safety procedures can prevent
accidents, equipment failure, and damage to the load.
Q: What are the common hazards associated with rigging?
A: Common hazards associated with rigging include equipment failure,
improper rigging techniques, falling objects, and unbalanced loads.
Q: Who is responsible for rigging safety?
A: Employers are responsible for providing a safe workplace and ensuring that
workers receive proper training and equipment. Workers are responsible for
following safety procedures and using proper techniques.
Q: What is the role of PPE in rigging safety?
A: Personal protective equipment (PPE) is essential in any rigging operation.
PPE includes hard hats, safety glasses, gloves, and fall protection equipment.
Questions and Answers

Cravans answer
• The SWL law said
SWL=(Totally Load weight/selection load ) * 100% =
So we impose the reduce equal 6 so the crane capacity will be 12.60 ton
SWL=(4.2/12.60)*100 %= 33.33 %
