SECURE
LIFT is a heavy duty non metallic sling, made
of polyester. These are flat woven webbing slings with
Eye-loop at the ends. These are available in different
lengths and different weight lifting capacities ranging
from 1 ton upto 48 tons.
The polyester webbing slings, with reinforced eyes at both sides, are
manufactured as per BS 3481 Part 1 and Part 2 1983 and EN 1492-1 norms.
The safety factor is 7:1.

RAW
MATERIAL CONSTRUCTION DETAIL
|
-
100%
industrial high tenacity Polyester multi filament yarn
having excellent light fastness and heat stabilization
with a tenacity not less than 60cN/tex is used to manufacture
slings with relative density of 1.38 and melting point
260°C. The safe working temperature for these slings
is –40°C to +100°C. Elasticity is 2.5% elongation
at SWL rated capacity and recovery is 95% after 24
hrs. Its electrical resistance , in dry state, tends
to infinity.
-
Thermal,
electrical and friction co-efficient as per the International
Code DIN-BN 1492-PART 2/BS 6668 PART 2/BS 3481 & PART
2 1983.
-
These
slings are highly resistant to mild acids, alkalis,
alcohol, bleaching agents, dry cleaning solvents, halogenate
hydrocarbons, ketones, crude oil, soap and detergents.

ADVANTAGES
OF SECRE LIFT POLYESTER SLING OVER METALLIC
SLING/CHAIN
- Lasts
long: Polyester sling is made
of Synthetic Polyester due to which it
can be used for a longer period of time
thus lowering its replacement costs, whereas
since the Metallic slings are made up of
Iron, it has a tendency to corrode over
a shorter period of time. Also the Polyester
Slings is Acid resistant unlike the Metallic
Sling.
- Much
lighter: Polyester sling is much
lighter than the Metallic sling thus making
them easier to handle and store. It also
reduces the rigging time hence making the
process of lifting material much faster
as compared to the Metallic Sling.
- Safety
of the product: Metallic sling
may sometimes damage the finished product
since its surface is hard and rigid. Polyester
sling being very soft does not pose any
such threat to the product.
- Safety
Factor: The safety ratio of the
Polyester sling is 6:1 and 7:1 as compared
to the safety ratio of 5:1 of the Metallic
Sling. It can therefore absorb shock loads
much better than the Metallic Rope.
- Dependability: Polyester
sling is more dependable than the Metallic
sling as they have a wider bearing surface
on the load and better grip owing to the
polyester material.
- Internal
damages: Metallic sling cannot
be physically checked for any internal
damages and hence may prove to be fatal
whereas the polyester sling can be easily
checked and accidents can be avoided.
|
-
Codification: Polyester
slings are divided into different colours
on the basis of their load taking capacity.For
eg yellow colour for 3 ton, whereas there
are no such colour codes to differentiate
between the different load lifting capacity.
In addition to the colour, the number of
black lines on the slings also indicate its
WLL/SWL
|

|

-
Safety
of the employees: Since
the Metallic sling is made up of rigid and
hard material there are greater chance of injuries
to the employees. Whereas the polyester sling
are made of very soft material so there are no
chances of any injury thus making them more user
friendly.
-
Eliminates
cost of consumables: Employee
does not require gloves for protection and grease
for lubrication while using polyester slings,
hence saves the costs on gloves and grease.
