UHMWPE, SuperMax Round Sling

SuperMax® Round Sling is made of Ultra High Molecular Weight Polyethylene (UHMWPE) yarn covered by durable nylon cover to make high performance lifting round slings.

While designing SuperMax® Round Sling, our goal was lightest lifting hear with higher breaking strength of wire rope.

SM Rope & Wire used our long experience of designing and manufacturing know-how’s to make SuperMax®Round Sling with low elongation while it is stronger than wire rope with less than 10% weight of wire rope.

Low elongation of SuperMax® Round Sling makes lifting job much easier and safer. Low elongation enables very low lash back.

Also SuperMax® Round Sling is very stable when used with hook, and you can avoid rotating problem of wire rope slings.

│Characteristics│

  • Easy to handle because it is flexible
  • The form of products didn't change even though they are used for a long time.
  • Low elongation but high safety

Weight
11.2Kgs/Pc
1/10 of wire rope of same breaking strength. Light weight enables easy installing and handling of sling, and higher productivity of lifting job.
117.0kgs/Pc
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.
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
Safe
Keeping
It is easy to keep them safely even in narrow space because they are fiber products.
We need wide space to keep them safely because they are Steel products

*Remark : Sharp contact areas is required for the safety guards.
