Polyester
Slings for Material Handling & Lifting
|
| |
| Our
specialty is heavy-duty non-metallic sling,
made of polyester. These are of flat webbing sling
with eye-loops at the ends. These are available in
different lengths & different weight lifting
capacities ranging from 1 ton to 10 tonnes. |
| |
| POLYESTER
WEBBING SLINGS |
| |
| The
Polyester Webbing Slings with reinforced eyes at
both sides are manufactured as per BS 3481 Part 1 & Part
2 1983. The safety factor is 7:1. |
| |
| PROPERTIES
OF SLINGS |
| |
|
1.
|
It
is of low weight, non corrosive, good resistance
to heat, excellent electrical insulation properties
and good chemical resistance as per specified
standard. Working temperature range-400 C
to + 1000 C. |
|
|
|
2.
|
It
does not have any fiber optic core. It will
not create sparks in explosives or hazardous
environments. |
|
|
|
3.
|
The
maximum permitted elongation is only 3% at
working load limit (WLL). |
|
|
|
4.
|
Safety
factor for sling is minimum 7:1. |
|
|
|
5.
|
Each
sling carries a tag indicating Sling No., Type,
WLL,
Load Test Date & Report No. |
|
|
|
6.
|
It
is suitable for choked lift (Choker mode) also. |

|
100%
Polyester Yarn used to manufacture Slings with
relative density of 1.38 & melting point
260 0, C. The safe working temperature
for these slings is (-)400 C to
(+)1000
C. Elasticity is 2.5% elongation at SWL rated
capacity & recovery is 95% after 24 hours.
Its electrical resistance, in dry state, tends
to infinity. |
|
|
|
|
|
Thermal,
electrical & friction co-efficient are
as per international code DIN-BN 1492-Part
2/BS 6668 PART II/BS 3481 1 & Part 2 1983. |
|
|
|
|
|
These
slings are highly resistant to mild acids,
alkalis, alcohol, bleaching agents, dry cleaning
solvents, halogenate hydrocarbons, ketones,
crude oil, soap & detergent |
|
|
|
|
| STRETCH |
| The
total stretch in fiber yarn of webbing may
be divided
into three distinct modes. |
| |
|
1.
|
Elastic
stretch – in which recovery after unloading
is total and immediate. |
|
|
|
2.
|
Recoverable
stretch difficult to allow for because recovery
towards the original length is gradual. |
|
|
|
3.
|
Non – Recoverable
stretch even the best webbings never quite
recover their original length due to changes
in intermolecular geometry. |
