RIGGER’S 10-STEP CHECK LIST
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.
Use the right
hitch. Decide how to connect your
load to the lifting hook and how to attach the sling
to the load.
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.
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
Rig up, not down.
Always attach the sling to the load first, then
attach it to the hook.
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. 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.
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.
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 tagline or tether. Be
sure to keep clear of the suspended load.
loading. Lift slowly with a steady
application or power. Don’t make sudden starts or
stops, either in lifting or swinging the load.
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.
