Calculating Sling Loading


56/70

Rigging Safety

56

Steps:1. Determine sling angles. (45)

2. Go to 2-leg bridle capacity column at 45

3. Select 2-leg bridle with capacity equal to or greater

than load to be lifted. ( inch rope diameter at 3.6 tons)

RB 50



57/70

Rigging Safety

57

Steps:

1. Determine sling angles. (45)

3. Multiply load weight byLoad Angle Factor to get

total load on sling legs.

(2000 lbs x 1.414 = 2828)

4. Divide total load by the

number of sling legs.

(2828 lbs 2 = 1414 lbs per sling leg)

5. Select slings from the single vertical leg column

within the sling capacity table.

2. Select corresponding

Load Angle Factor. (1.414)

RB 51



58/70

Rigging Safety

58

Steps:

1. Divide length by height to get Load Angle Factor.

( 6 ft 4 ft = 1.5)

2. Multiply Load Angle Factor by load weight to get

total load on sling legs.

( 1.5 x 2000 lbs = 3000 lbs)

3. Divide total load by number of sling legs to get

load on each sling leg.

( 3000 lbs 2 = 1500 lbs per sling leg)

4. Select slings from the single vertical leg column

within the sling capacity table.
