SuperMaxTM Round
Sling is made of Ultra High Molecular Weight Polyethylene
(UHMWPE) yarn covered by durable polyester cover
to make high performance lifting round slings.
While designing SuperMaxTM
Round Sling, our goal was lightest lifting hear
with higher breaking strength of wire rope. DSR
used our long experience of designing and manufacturing
know-how’s to make SuperMaxTM
Round Sling with low elongation while it is stronger
than wire rope with less than 10% weight of wire
rope.
Low elongation of SuperMaxTM
Round Sling makes lifting job much easier and
safer. Low elongation enables very low lash back.
Also SuperMaxTM Round
Sling is very stable when used with hook, and
you can avoid rotating problem of wire rope slings.

Comparison of SuperMaxTM Round Sling and Wire
Rope Sling |
|
|
SuperMax
Round Sling |
Wire Rope
Sling |
|
Weight |
1/10 of wire rope of same breaking strength. Light
weight enables easy installing and handling of
sling, and higher productivity of lifting job. |
Because of heavy weight,
it's very difficult to move and install the
slings. Heavy wire rope sling can cause back
pain of the users. |
|
|
|
|
|
Stability |
Do not damage the material to be lifted. Positioning
is fast and easy. Can tighten up the material
to avoid slip while lifting the products. |
Can hurt the material to be lifted. Positioning
is slow and difficult. |
|
|
|
|
|
Durability |
Durable against chemical contacts. Because of
the flexibility, its bending ratio can be far
smaller. |
Easy to get rusted against acid or alkali. Because
of stiffness, broken wire can occur unless extra
care is taken. |
|
|
|
|
Storability |
Only small storage space is required because of
its flexibility. |
Large and dry storage space is
required. |
|
|
|
Economical Value |
High initial investment cost. However, higher
productivity, longer service life, easier handling
and storage result in low total operation costs. |
Low initial cost. However, more manpower and heavier
equipments to move, install, and lift are required.
Total operating cost is high. |
