The art of the round sling
The round sling is made by fiber, the inner load-bearing core is formed by endless circled , the outside is braid sleeve to protect the load-bearing fibers.
Characteristics
1.low elongation ,working load≤3%,breaking load≤10%.
2. The maximum load reach to 1000t, the effective length can reach to 100m
3. It is very convenient to operate even in a small space .
4. The Security insurance coefficient is 6:1
5. Lifting objects is protected effectively.

care and use of sling
1.lifting sling with the surface damage is an important factor in reducing the strength .When the surface tear , the tape will rapidly damage. The surface fiber fracture ( not the fault ) , as long as the scope is not too big and it would not affect.
2: Never exceed the working load limit of a chain sling.
3.Shall not focus on the way that use bolt to lift without protection .
4: The soft ring’s lifting device must be:
A: smooth without any sharp edges
B: its should not be torn or the belt overload .
5: Lifting should observe the following measures.
A: do not shockloas when moving
B: not to tie belt
C: Eliminate all twists, knots or kinks before lifting.
D: Do not use the sling (with no pads) to lift the cargo which is sharp or having edages , especially when belt has some abrasion or wear .
E: do not lift goods too much time
F: DO not take away the strap when it working
G: notice the load
H: avoid soft ring angle opened more than 20 degree.
6: ensure the load unchanged when it working . if several belts use in the same time , as far as possible balance the load.
7: if used in high-temperature occasions or lifting chemical substances , should be in accordance with the manufacture and distributor of the guidance . tape dirtied or have been used in acid-base environment should be immediately washed with clean water.
8: sling should be kept in the place where can avoid light and no UV radiation .
9: sling should not be kept in the place where have spark or heat around.
10: each tape should be carefully examined before use.
11: Return slings to manufacturer to ensure proper repair procedures are followed.
12: Store chain slings in a clean, dry area, preferably by hanging on racks or A-frames
