DALE Types of Sling Legs

Typical Sling Arrangements

When single leg slings are used either alone or in pairs, the Safe Working Load (SWL) can be affected.

Some examples are given here.

Cradle Sling Lifting coils, steel strip, etc. Basket Hitch SWL = 1.4 x WLL of sling Protect Rope from sharp corners.
Cradle Slings Lifting boilers and packaging cases, etc. Double Basket Hitch SWL = 2.1 x WLL of sling.
Halshing Slings Method using a single sling in place of an endless sling where a ‘bight’ is required. A stirrup fitted temporarily in the bight will minimise damage to the sling. Double and Choked. SWL = 1.6 x WLL of sling.
Double Wrap Slings Note how the double wrap grips the load and helps to prevent it from slipping sideways out of the slings. Double Wrap Basket Hitch SWL = 2.1 x WLL of sling.
Combination Slings Timber steel sheets and packing cases, etc. N.B. Maximum angle between legs is 90º
Reeving Slings Lifting tubes, bars and rods, etc. Double Choke Hitch SWL = 1.1 x WLL of sling.
