wider Gujarat industrial belt (Vapi, Ankleshwar, Bharuch, etc.); Mumbai, Pune,
Nagpur, Nashik in Maharashtra; key Southern cities including Hyderabad,
Chennai, Bangalore, Vijayawada, Coimbatore; major centers in Odisha
(Bhubaneswar, Cuttack, Rourkela); Madhya Pradesh (Indore, Bhopal); and across
Rajasthan (Jaipur, Ajmer, Udaipur, etc.), Jharkhand, and Bihar."
Key Characteristics and Types
·
Materials: Primarily made from nylon or
polyester. Nylon typically offers high stretch (up to 10%), making it ideal for
shock absorption, while polyester has low stretch (approx. 3%) and offers
better resistance to acids and water.
·
Webbing Slings: Flat, woven synthetic straps
with eyes at both ends, designed for versatile lifting, including choker,
vertical, or basket hitches.
·
Round Slings: Endless loops of fibers covered
by a protective jacket, often used for heavy-duty lifting and better load
distribution.
Key Advantages
·
Load Protection: Their soft material minimizes
damage to surfaces of delicate or finished loads.
·
Lightweight & Flexible: Easy to
handle, rig, and store, reducing operator fatigue.
·
Corrosion Resistance: Unlike wire
rope, they do not rust, making them ideal for marine environments.
Common Applications
·
Construction sites for lifting materials.
·
Marine and offshore projects.
·
Handling machined parts, specialized equipment, and fragile cargo.
Note: As per this OSHA guidance, synthetic web
slings must be thoroughly inspected for damage before each use

This technical
reference is designed for procurement officers, site supervisors, and safety
managers. It provides a standardized guide to identify safe working loads (SWL)
for synthetic webbing slings, compliant with international and Indian safety
standards (EN 1492-1).
The
industry-standard color-coding system allows for immediate visual verification
of a sling's capacity on the job site.

Note: Always verify the
manufacturer's tag stitched onto the sling for the exact SWL, as variations in
material construction can affect final load ratings.
The effective Safe
Working Load (SWL) of a sling changes depending on how it is attached to the
load. Use the following Load Factors to calculate the adjusted capacity
for your specific lift configuration.

To maintain safety
and equipment longevity, adherence to these protocols is mandatory for all site
operations.
·
Check for Cuts & Tears: Any superficial damage that penetrates the webbing
surface requires immediate retirement of the sling.
·
Chemical/Heat Damage: Inspect for brittle areas, melted fibers, or
discoloration, indicating environmental degradation.
·
Legible Labels: If the identification tag is missing or illegible, the sling must be
removed from service immediately.
·
Sharp Edges: Always use Apex Global Corner Protectors or protective sleeves
when lifting loads with sharp edges or abrasive surfaces.
·
Environmental Control: Store slings in a cool, dry environment, away from
direct sunlight (UV degradation) and corrosive chemical vapors.
·
Proper Hitching: Avoid twisting or knotting the webbing. Ensure the load is evenly
balanced across the sling body.
