About Round Slings for Lifting
Round slings are commonly associated with hoisting equipment for lifting applications. Our polyester standard round slings are made from high quality polyester yarn that makes up the core and can be produced with different sleeve qualities.
Synthetic Web Slings – High-Performance Soft Lifting Solutions
Synthetic web slings are high-performance soft lifting slings made from premium high-tenacity, low-elongation polyester fibers. They are regarded as the next-generation alternative to traditional wire rope slings.
In many industrially developed countries, synthetic slings have been widely used for over 50 years, and their superior performance has earned them great popularity among users.
Main Features:
-
Lightweight and Flexible:
Only 25% of the weight of equivalent metal slings, making them extremely easy to handle, transport, and store.
They reduce the risk of damage to delicate or coated surfaces during lifting operations and cause no harm to operators. -
Safe and Reliable:
These slings offer shock absorption, corrosion resistance, aging resistance, and non-conductivity.
They generate no sparks in flammable or explosive environments.
Under rated load, the elongation is about 1.6%, with tensile properties similar to wire rope.
Their condition is easy to inspect — if a sling appears intact, it can generally be considered safe for use.
Type I – Polyester-Sleeved Dyneema Sling
The core material of this sling is made from Dyneema® SK75, an ultra-high-strength fiber imported from DSM Dyneema in the Netherlands.
Produced with LDR’s advanced manufacturing process and equipment, the outer sleeve is made of thickened, heat-treated polyester, providing excellent abrasion resistance.
This type of Dyneema sling is lightweight yet extremely strong — weighing only one-eighth the weight of synthetic fiber slings and one-tenth that of wire rope slings.
It is easy to handle and operate, making it highly practical.
Currently, it has been adopted by several railway bureaus in China as part of their train rescue equipment due to its safety, portability, and reliability.
Type II – Dyneema-Sleeved Dyneema Sling
For this model, both the core and the protective sleeve are made entirely from Dyneema® SK75 ultra-high-strength fiber, imported from DSM Dyneema, Netherlands, and produced using DSM’s proprietary technology.
This sling is designed for use in harsh environments, offering exceptional resistance to chemical corrosion, UV radiation, fatigue, cutting, and abrasion.
Instruction For Round Slings
Application
Round slings are ideal for lifting, securing, and positioning loads in construction, manufacturing, shipping, and offshore industries. Their endless loop design offers excellent flexibility, even load distribution, and protection for delicate surfaces, making them suitable for machinery, pipes, steel structures, and heavy equipment.
