This document provides information on safe rigging practices when using cranes and rigging equipment. It notes that over 70% of crane accidents involve mobile cranes and are often due to negligence of safe rigging practices. Proper inspection and maintenance of equipment as well as ensuring operators are trained are emphasized. Guidelines are provided for inspection of wire rope slings, shackles, and general sling operating practices to prevent accidents and ensure safety.

1. When rigging, always use
the correct signs!!!

CRANE SAFETY AND PRECAUTIONS
 Operators must be physically fit and well trained i.e.
they must know the signals and operations involved.
 Both periodic (e.g. annual) and frequent
(daily/monthly) inspections must be carried out of
crane components and operation.
 Use warning signs and proximity alarms to avoid
power line contact.
RIGGING STUDY
 Assure a level and stable base for the crane

2. SAFE RIGGING PRACTICES
WIRE ROPE SLING REPLACEMENT
 Check for randomly distributed broken
wires.
 Check for severe localized abrasion or
scraping.
 Check for kinking, crushing, bird-caging or
any other damage resulting in distortion of
the rope strands and wires.
 Check for the evidence of heat damage or
exposure to severe heat, also check for
cracked and corroded end attachments
RIGGING COMPONENTS SAFETY
SHACKLE INSPECTION AND USE
o Always tighten the pin securely in
place
o Check the shackle pin, ears and
bail for deformation cracks before
each lift
o Never weld on to a shackle body or pin
o Never substitute a shackle pin with anything other
than the exact replacement pin from the
manufacturer
o Never force too small a shackle onto a hook

 Look for any overhead power lines before starting the
process
 Establish proper communication with the responsible
person
 Check the Working Load Limits (weight of the load,
center of gravity, sling angle, side loading, capacity of
the gear etc.)
 Check for unusual loading and environmental
conditions, e.g. high speed wind conditions.

BASIC SLING OPERATING PRACTICES
(ANSI B30.9)
Whenever any sling is used, the following practices
shall be observed!
1. Slings that are damaged or defective shall not be
used.
2. Slings shall not be shortened with knots or bolts or
other makeshift devices.
3. Sling legs shall not be kinked.
4. Slings shall not be loaded in excess of their rated
capacity.
5. Slings used in a Basket Hitch shall have the load
balanced to prevent slippage.
6. Slings shall be securely attached to the load.
7. Slings shall be padded or protected from the sharp
edges of their loads.
8. Suspended loads shall be kept free of obstructions.
