GOOD SLINGING PRACTICE<br />
BASIC RULES ... 3<br />
3.4. FINDING THE INCLUDED ANGLE.<br />
How do you work out or measure the "included angle" in a set of slings?<br />
As you will now be aware, an included angle of more than 120° is not an option. The<br />
stresses on the sling start to increase dramatically once the angle of 120° is exceeded.<br />
It is a <strong>good</strong> <strong>practice</strong> to keep the sling included angle at a maximum of 60°.<br />
60° is obtained when (L) - the distance between sling attachments - is<br />
EQUAL to (S) - the sling length.<br />
90° is obtained when L is 1.4 times S.<br />
120° is obtained when L is 1.7 times S.<br />
