l)
Before lifting in a chemically active environment, be sure that the sling
material is resistant to the chemicals involved.
m)
Follow good sling usage practice: Sling placement, lifting, and lowering
operations should be planned before lifting begins.
n)
Slings should be properly positioned and connected to the load in a safe
manner. Slings should be placed on the load so that they are able to assume a
flattened shape and the load is uniform across their width.
o)
In the case of multi-leg slings, WLL values are determined on the assumption
that the load on the sling assembly is symmetrical. This means that when the
load is lifted, the sling legs are symmetrically distributed in the plane and
inclined at the same angle to the vertical.
p)
In the case of slings with 3 legs, if the legs are not symmetrically distributed in
the plane, the highest stress occurs in the leg in which the sum of plane angles
with adjacent legs is the greatest. The same effect occurs in slings with 4 legs,
except that the stiffness of the load must also be taken into account.
DANGER!
It is forbidden to use a sling that:
- is without a label or has an illegible label,
- has been damaged by acidic or alkaline substances Chemicals will weaken the
material,
- is damaged in any way, including, but not limited to, chafed, cut, torn, punctured,
or has cracked or worn seams. Any damage will cause the fabric to be weakened,
- has an exposed core,
- has knots in any part of the sling,
- has been deformed by heat,
- has been exposed to prolonged sunlight,
- in any way casts doubt on sling's strength.
SLING INSTALLATION:
a)
Do not place sling seams (stitched parts) on attachments such as hooks,
shackles.
b)
The load applied to the hook should be centered in the base (bowl) of the hook
to prevent point loading of the hook.
c)
Slings with attachments (e.g., hooks, shackles) that are used in a pinch hitch
shall be long enough so that the pinch loop is on the belt and not on the
attachment.
d)
The load to be lifted must always be protected from sharp edges, corners or
abrasive surfaces so as not to damage the sling.
e)
The load's center of gravity should be located between the sling's attachment
points.
