Round sling is both high strong and non-damaging to its load.Extremely light in weight and infinitely flexible in all directions,it is easy and quick to manipulate even when awkwardly shaped or fragile loads are being lifted.It can be used for machining, shipbuilding, power installation, transportation etc.Round sling max load can reach 3000 tons and the effective length can reach 100 meters. The safety factor is generally 7:1 and 6:1. Circular lifting roundsling is high strength polyester industrial filament made from 100% (PES),external use 100% PES woven stress of casing for bearing core is protected.
