HOW DO WE REDUCE RISK
THROUGH KNOWLEDGE?
Industrial Splicing & Sling was started in 1940. It became
the largest Sling Fabricator in Tulsa, Oklahoma. We
manufacture lifting gear for just about any material handling
application imaginable.
“BUT THAT’S NOT WHAT MAKES US
UNIQUE IN OUR MARKET PLACE”
What makes us unique in our market place is our ability to
reduce our customer’s cost by reducing their risk exposure
to material handling through training and inspection of
rigging gear.

REDUCING RISK THROUGH KNOWLEDGE
1. We represent leading “USA Brands” that perform and
support their products.
2. We provide practical and effective rigging and application
training that meet ASME and OSHA requirements at no
cost to you.
3. We provide effective and comprehensive sling inspection
that meets OSHA and ASME requirements for our
customers at no cost.
4. We provide Technical and Safety information through our
“White Papers” Program to assist in your compliance
efforts.
5. We operate the largest Testing facility in our markets.

WHAT DO THESE
STATISTICS INDICATE?
 ASME and OSHA recognizes that the use of rigging gear
in lifting is very different from commodities such as
ordinary hand tools.
 They require training, inspection, quality products, and
knowledge to safely use rigging gear.
 Based on the latest National Safety Council's – Injury

fatality will cost $1,390,000.

Lifting Safety Facts
ASME B30.5 has been rewritten to include extensive discussion of
planning lifts. Detailed requirements for the Qualifications and
Responsibilities of Crane Operators, Site Supervisor and Lift Director
clearly define key elements.
OSHA RULE FOR CRANES AND DERRICK IN CONSTRUCTIONS 1926
Subpart CC (1926.1400 - 1926.1442 and Appendix A,B,C) provides clear
guidance in all aspects of managing the lift. This includes Operator,
Rigger and Signalperson qualifications, training and responsibilities as
well as work area control and other topics.
ASME P30 Committee has been formed to the development and
maintenance of standards that support lift planning activities where
mechanical equipment including, but not limited to, cranes, derricks,
hoists, cableways, aerial devices and material lifting accessories and
combinations there of are used.

Best Practices

Lift Planning and Preparation:
Important steps before Lifting:
• “Know” the load to be lifted
• Determine the number of legs and the horizontal
sling angle
• Verify the rated capacity of sling(s)
• Determine condition of sling and other rigging
gear
The load first:
• Size (dimensions)
• Lifting Points
• Weight and composition
• Center of gravity
• Sharp corners
• Finish conditions and requirements

AllRightsReserved
“SLINGS”
Best Practices
Slings
BestPractice
Execution of Lift:
Rig to center of gravity:
• Locate load hook over load COG
• Attach slings
Balance the load
• Place rigging into base of hook
• Verify that the load lifts level
• Prevent slippage of load in basket hitches
• Connect or support the load above COG
Test the rigging
• Tug rigging to verify alignment and security
• Lift slightly off ground and recheck
Stand clear and lift, avoiding shock loading
Return rigging to storage

Activities
BestPractice
Horizontal sling angle
• 60 degrees is best choice
• 30 degrees is minimum angle (not recommended)
• Locate load hook over load COG and attach slings
Sling tension increases as horizontal sling angle decreases
• Load on sling increases
• Load on hardware increases
• Must match load weight for multiple leg sling tag
To determine required shackle capacity
• Determine horizontal sling angle (L/H)
• Determine angle multiplier
• Calculate share of load
• Calculate sling tension = “load share” x “multiplier”

How to Inspect Wire Rope Slings (Periodic):
• Place sling in position that enables inspector to
access and see every part of sling
• Clean off dirt and grease sufficiently to reveal
wires and fittings
• Pay special attention to fittings and end
attachments and the wire rope at termination
• Find most worn or damaged area first, check
against removal criteria
• Examine entire length of sling
• Identify and control all slings inspected
• Maintain records of the inspection
• “Red Tag” all rejected slings
Store slings that are determined as acceptable in a safe place from
damaging weather conditions, heat, dirt and physical damage (trucks,
forklifts, etc.)
