RIG CH.6 Flashcards
1
Q
Explain the relationship between sling angle and sling tension.
A
As the sling angle decreases, the tension on each sling increases substantially
2
Q
What is the sling tension formula?
A
Sling tension = Sling length/Sling height * weight/# of slings
3
Q
What condition must be present to use the sling tension formula?
A
Sling length and weight distribution of load must be equal on all slings when using the formula.
4
Q
How should the sling be when installing an overhead transformer?
A
Sling must be as short as possible to maximize the lift
5
Q
