An Endless Wire Rope Sling (Locking Type) is a heavy-duty lifting sling made from a continuous loop of wire rope, secured with a locking sleeve or ferrule for maximum strength and durability. These slings are commonly used in rigging, construction, marine, and industrial lifting due to their flexibility, abrasion resistance, and ability to handle extreme loads.
Key Features
- Continuous loop design – No splices or knots, distributing load evenly.
- Locking sleeve/ferrule – Crimped or swaged for a permanent, secure connection.
- High load capacity – Rated for 1-ton to 100+ tons (varies by diameter & construction).
- Durable & weather-resistant – Works in harsh environments (oil, chemicals, UV exposure).
- Flexible & kink-resistant – Can be used in basket, choker, or vertical hitch configurations.
How to Use an Endless Wire Rope Sling (Locking Type)
1. Inspection Before Use- Check for broken wires, corrosion, or deformation - Ensure the locking sleeve is intact and not cracked or loose.- Verify the WLL (Working Load Limit) matches your load.
2. Selecting the Right Hitch- Vertical Hitch – Straight lift, full WLL.- Basket Hitch – Doubles WLL (if legs are vertical).- Choker Hitch – Reduces WLL by ~25% (due to sharp bends).
3. Rigging the Sling
- For a Basket Hitch:
- Loop the sling under the load.
- Attach both ends to the hook/lifting device.
- Ensure equal load distribution.
- For a Choker Hitch:
- Pass one end through the other, forming a noose.
- Tighten around the load and connect to the lifting device.
4. Lifting Safely
- Avoid shock loading – Lift gradually.
- Protect sharp edges – Use padding to prevent rope damage.
- Keep personnel clear during lifting.
Safety Tips
- Never exceed WLL – Factor in hitch type and angle.
- Avoid sharp bends – Minimum bend radius = 2x sling diameter.
- Store properly – Hang in a dry place to prevent kinks/corrosion.
- Replace if damaged – Frayed wires, crushed ferrules, or deformation mean it’s unsafe.
Common Applications
- Construction – Lifting steel beams, precast concrete.
- Marine/Offshore – Securing heavy cargo, shipbuilding.
- Mining/Oil & Gas – Rigging pipelines, machinery.
- Wrecking & Recovery – Moving debris or vehicles.
