Rigger Checklist

rigger checklist
1.
Weigh and measure
Before you lift, be sure you know
exactly how much weight you’re
moving, how far you have to move it
and how high you must lift it. Make
sure the load’s weight is within the
rated capacity of the sling, including
consideration of sling leg angles and
load’s physical parameters.



2. Use the right hitch
Decide how to connect your load to
the lifting hook and how to attach
the sling to the load.



3. Choose the right sling
Each load is different. Be sure to
calculate the proper rated capacity
for the angles and hitch involved as
well as the right type and style for
the job.
If D/d ratios are smaller than those
indicated, the sling’s rated capacity
must be reduced. Choose a sling with
the proper end attachments or eye
protection as well as attaching
hardware. Pad all corners in contact
with the sling to minimize damage
to the sling.

4. Inspect the sling

Check the sling closely to be sure
it is in good condition and able to
make the lift. Follow all the appropriate
OSHA guidelines and ASME
regulations. You cannot change
the length of a sling. If a different
length is needed, get a sling of the
required length.



5. Rig up, not down
Always attach the sling to the load
first, then attach it to the hook.



6. Balance the load
Always place the eye or link in the
base (bowl) of the hook to prevent
point loading on the hook. In a basket
hitch, always balance the load to
prevent slippage.
The sling’s legs should contain or
support the load from the sides above
the center of gravity when using a
basket hitch. Be certain that the
slings are long enough so that the
rated capacity is adequate when you
consider the angle of the legs.

7. Test the rigging

Before you make the lift, tug lightly
on the rigging to be certain that
blocking, sling and load protection
are in place, then lift slightly off the
ground and re-check the lift.



8. Stand clear and lift
To prevent injury, move away from
the areas between the sling and load
and between the sling and the crane
hook or hoist hook. Let the lifting
device and rigging work for you.
Avoid the temptation to use your
muscles to prevent swinging or
movement. Use a tag-line or tether.
Be sure to keep clear of the
suspended load.



9. A void shock loading

Lift slowly with a steady application
or power. Don’t make sudden starts
or stops, either in lifting or swinging
the load.



10. Return to storage
After you’re done with your lift,
inspect the sling for possible damage.
If damaged and not usable, destroy
the sling immediately. Otherwise,
return it to your sling storage rack
until your next lift.
