To protect the round slings from cut while using on sharp edges Anti-Abrasive and Anti-cut sleeves must be used. There are basically 2 types of sleeves available for round slings.
1. Movable type sleeves- slide freely on sling but cannot be removed.
2. Quick Sleeve – Slide freely on sling and removable have Velcro.
All these slings are available in different types of material i.e. Polyester, Kevlar, High Molecular Polyethylene (HMPE), Polyester with PU impregnated, Polyurethane blended Polymer and Polyurethane.
Use Anti-Abrasive, Anti-cut Sleeves to protect round slings from damage by sharp edges, we have wide range of protection sleeves (see Sling Protection).
Aperture angles of eyes should not be more than 20°. It means length of the eye equals or exceeds four times the area of support of the lifting hook.
FERRETERRO Twin slings are available in Polyester/Dyneema® fibers by DSM load carrying fibers.
Twin slings are actually two complete and separate slings in one. Each path makes its own separate connection between the hook and the load and account for 50% of the total slings work load. The design we manufacture is non patented and is cost effective than other sling makers.
DOUBLE CORE (ON REQUEST)
The twin sling design provides the sling user with an early warning and inspection system. Also available in double core for extra abrasion resistance and long life. The load carrying yarn never come into contact with the load. When the protection outer cover is damaged, the inner cover provides extra protective sleeve for usage.
ELONGATION STRING (FREE)
We provides all our round slings, and TWIN sling as well with Elongation string to know whether the sling has elongated and when the string disappears sling should be discarded.
FIBER-OPTIC INSPECTION (FREE)
Fiber optic inspection cables assist the sling user and inspector to evaluate the condition of the load carrying yarns. The condition of internal load carrying yarn can be inspected by checking the conductivity of the fiber optic cable. If the load carrying yarn have suffered chemical, heat or crushing damage, the fiber optic will lose its ability to transmit light from one end to the other, giving the inspector a reason to remove the sling from service and return it for repair evaluation.
