Precautions for Using Nylon Sling
1. Follow the precautions below to use nylon slings
safely.
• Attach protectors (soft material) on the corners of
the load so that the nylon sling does not directly
contact the corners. This will prevent the nylon
sling from being damaged and the lifted load from
slipping.
• Lower the temperature of the lifted load to lower
than 100 C (212 F). If unavoidably lifting a load
with a temperature of 100 C (212 F) or more,
reduce the load weight.
• Do not lift acid or alkali chemicals.
• Take care not to allow the sling to become wet.
The load may slip.
• When required to use more than one sling, use
slings with the same width and length to keep the
lifted load balanced.
• When lifting a load using an eyehole, be sure to
eliminate any gaps between the sling and load.
(Refer to the right illustration.) Reduce the load
weight so that it is less than 80 % of the sling
breaking force.
• Avoid using twisted, bound, connected, or
hitched slings.
• Do not place any object on twisted or bent slings.
(Refer to the right illustration.)
• When removing the slings from under the load,
take care not to damage the nylon slings. Avoid
contact with protrusions.
• Avoid dragging slings on the ground, throwing
slings or pushing slings with a metal object.
• When using with other types of slings (wire rope)
or accessories (shackle), protect the joint so that
the nylon sling is not damaged.
• Store the nylon slings indoors so they won’t dete-
riorate with heat, sun light, or chemicals.
