Three Leg Wire Rope Sling for Lifting

Three Leg Wire Rope Sling

Gostern Three Leg Wire Rope Sling is engineered for stable, balanced lifting of irregularly shaped, triangular, or round loads using three attachment points. This sling features a common master link at the top for connection to the crane hook, and three wire rope legs each terminated with hooks, shackles, or eyes for load attachment . The three-leg design provides superior load stability compared to two-leg slings, automatically distributing the load evenly and preventing load tipping, making it ideal for loads with three lifting points or uneven weight distribution . Available in pressed (swaged) or hand spliced construction, with galvanized or ungalvanized (bright) finish .

This Triple Leg Wire Rope Sling is manufactured from high quality 6×37 or 6×19 wire rope , providing an excellent balance of flexibility and strength. The master link is forged from high-strength alloy steel, ensuring reliable connection to the lifting hook. The three-leg design offers automatic load balancing – if the load is not perfectly level, the shorter legs will take more load, but the design inherently accommodates some unevenness . For rigid loads, it should be noted that only two or three legs may actually bear the load , so the rated capacity assumes reasonably even load distribution . It is widely used as 3 Leg Bridle Wire Rope Sling for lifting round tanks and vessels, as Pressed Triple Leg Sling in construction and manufacturing, as Three Leg Lifting Sling for Irregular Loads in shipbuilding and heavy equipment transport, and as Galvanized Three Leg Sling for outdoor and marine applications . Available in wire rope diameters from 8mm to 32mm , with standard leg lengths from 1m to 10m (custom lengths available) , and working load limits (WLL) ranging from 880 kg to 9,500 kg per leg , with total sling capacity dependent on the included angle between legs .

Leg Configuration Capacities (Total Sling WLL) :

• Vertical Lift (0°) : 3 × single leg WLL

• 30° Included Angle (60° from vertical) : 2.6 × single leg WLL

• 45° Included Angle (67.5° from vertical) : 2.1 × single leg WLL

• 60° Included Angle (75° from vertical) : 1.5 × single leg WLL

Termination Types:

• Pressed (Swaged) : Aluminum ferrule, compact, smooth, 90-95% efficiency

• Hand Spliced: Traditional hand tucking, flexible, 80-90% efficiency

End Fitting Options:

• Hooks (吊钩) : Slip hooks, grab hooks, eye hooks, swivel hooks

• Shackles (卸扣) : Bow shackles, dee shackles

• Eyes (眼型) : Soft eyes, thimble eyes

• Combinations: Mixed fittings on each leg as required

Three Leg Sling Advantages:

• Automatic load balancing: Three legs provide inherent stability

• Prevents load tipping: Ideal for irregular or round loads

• Even load distribution: Better weight distribution than two-leg slings

• Versatile: Suitable for triangular, round, and irregular shapes

• Increased safety: Reduces risk of load shifting

Common Applications:

• Round tanks and pressure vessels

• Concrete pipes and culverts

• Industrial equipment and machinery

• Shipbuilding (hull sections, propellers)

• Heavy equipment transport

• Round structural steel elements

• Transformer and generator lifting

• Construction material handling

Important Usage Guidelines:

• Ensure all three legs are properly attached to the load before lifting

• For rigid loads, be aware that only two legs may initially bear load – use appropriately rated sling

• Do not exceed the rated capacity for the specific included angle

• For included angles over 60°, capacity is significantly reduced – use longer legs

• Always position master link directly above load's center of gravity

• Inspect master link, wire rope, and end fittings before each use

• Protect wire rope from sharp edges using edge protectors

• Regular inspection per ASME B30.9 standards

• Replace sling if wire rope shows broken wires, kinking, or severe corrosion

• Store slings in dry, clean area when not in use

We support Custom Length Three Leg Sling, OEM, ODM and various end fitting configurations to meet different lifting requirements.
