Sling Angles
1
Q
What is the tension on the sling equal to when a single sling in a vertical configuration supports a load?
A
The load weight
2
Q
What happens when the sling angle decreases?
A
The tension on each sling increases substantially.
3
Q
How can Sling Tension be calculated?
A
Sling Tension = (Sling Length/Sling Height) x (Weight/# of Slings)
4
Q
When are Sling Angles most commonly encountered?
A
When Lifting Wire Reels or when installing Transformers
5
Q
When installing a Overhead Transformer how should a sling be installed?
A
The sling must be as short as possible yo maximize the lift to allow room below the conductors for the derrick.
6
Q
What does a skilled lineworker know?
A
That Sling Angles can create tension that far exceed the weight of the load being lifted.
